Nissan Truck Crank NO-START when COLD - Part 2

[@northtrader]

Thanks very much for taking the time to record this 2 part series. I was very insightful. I have an '07 titan that I bought new, live in northern Minnesota and have never had this issue through 15 winters in which multiple -20F days per winter and a brutal -40F day a few years ago. The Titan fired up every time - until this morning! It was only about 0F (-18C) and it was the dreaded 'crank NO-START' phenomenon. I'm thankful I found this series of videos. I tried the cam sensor replacement and the truck did fire up and remain running but I don't think I'm out of the woods yet. Thanks again for this detailed look at the problem. Follow-up information below: It was a bad ECM and I had to replace all three camshaft position sensors. After I replaced the ECM, I was getting P0340 camshaft position sensor Bank A (drivers side) errors (even though the truck would start). I replaced the phase sensor (the one on the end of the block on the drivers side) first, cleared all codes and fired it up. Still got P0340 immediately. Then I replaced the camshaft position sensor on the drivers side top of the block, cleared all codes and fired it up. Got P1145 - camshaft position sensor issue on Bank B (passenger side). Replaced this camshaft position sensor (top of block on passenger side), cleared all codes and fired it up. No codes - no issues since. Just because I'm too curious, after replacing all three camshaft position sensors I was wondering if it was the ECM or just the sensors. I put my original ECM back in the truck just to satisfy my curiosity - and - CRANK NO START was immediately experienced. That satisfied my curiosity that the ECM did need to be replaced as well. I re-installed my new ECM and the truck has been starting and running great ever since. For those interested I installed the Duralast Camshaft Position Sensors SU5745 from Autozone. They were identical to the original sensors in my 2007 Titan.

If it didn't set any codes, then likely a ECM issue 👍

[@tommytwice1919]

Iam having the exact same issue with my truck starts fine unless it's below freezing. Replaced cam and crank sensors with factory nissan stuff still doing the same thing no codes present. Where did you buy your ecm from

[@Ticoresto]

I’ve had this problem for two years but it was mainly only an issue in the winter so I just put up with it until recently when it got worse. Much diagnostic was done and parts replaced. I found another video where the mechanic discovered that the positive battery fusible link was bad and he replaced it. I inspected mine and observed that my battery fusible link was corroded. It was a $20 part with discount from Advance so I replaced it. No more issues!! She starts right up on frigid mornings and when parked for days. I would have the worst problems in cold mornings and if it sat for days without use. Just wanted to share this so that others can try this simple inexpensive solution first. I may do a video so that other Titan owners don’t throw away needless amounts of money on functioning parts.

[@ecaparts]

Its all those bad Electrolytic Capacitors!! Just a thought... I see more and more problems with electronics starting at 5 years old depending on heat exposure. The liquid electrolyte dries and the ESR (equivalent series resistance) goes up. In other words, you start having inaccurate sensor values and random issues. Another great case study, Thanks Ivan!!

[@SeersantLoom]

There might be more than just caps. It seems to me that the way of cost/profit optimization tries to cut every possible corner there is. I started to notice this first when reading camera specs - my old film camera (not a pro cam, mind you) was rated to work between -20 to 30 or 40C (and it did, I really went out to shoot at -22C). Newer consumer/amateur cameras (especialy because of their puny Li-batteries) - not so much. Lowest temperature - 0C or -5C. Thats it and even this seems to be overrated marketing wank because the number of frames drops like stone at cooler temps. Use external battery? Yes, it helps. But then you'll notice that backlights and/or LCD screens stop working etc. Electronic components (chips, transistors) are binned and it goes from milspec to consumer grade. The latter being the cheapest but also the most crappiest (say - works ONLY at room temp, forget below freezing). Some factories experiment with newer tech, sometimes that does not stand the test of time. Some start to cut corners in existing production. Can't trust the solder used or boards themselves (board becoming conductive, microcracks in traces) etc etc. So, I would not be surprised that some cars are built the same way.

[@adotintheshark4848]

also, microprocessors can become cold sensitive. I remember working on GM-900 clusters that were completely dead in cold weather. Blow hot air on the micro and they came alive.

[@prmayner]

ECM's are the only thing that has ever fixed these trucks for me, that and what I call TIPM's. Thanks Ivan.

[@lonwillis783]

Wow put some supercaps on the battery to maintain voltage. LOL thanks Ivan.

[@vickenkaragozian2041]

There is bulletin on snap on. U might need pcm relay coz if voltage drops below 9’6 v the injectors will not pulse. The easiest way to check the ignition coil battery voltage while cranking. If it drops below 9.6 or less then check the battery first then the relay. Swap the defrost relay with pcm relay a nd see if starts right away

[@PineHollowAutoDiagnostics]

Voltage was good on all relay outputs; we proved that in Part 1 :)

[@Thunderroad8517]

Thanks Ivan for another Curveball Diagnosis! Its getting to the point we are gonna have to charge more time for research and more for scopes to do our jobs. I don't think Amazon sells crystal balls to know what the diagnosis is in 30 minutes to and hour. Thanks for following up and being persistent. Keep them coming.

[@carolb9422]

Hi Ivan. Love your videos. On my sailboat, starting the engine causes a voltage drop that makes electronics like chartplotters restart, loosing data and needing for a minute or so while they reacquire satellites. I did everything I could to reduce the voltage drop but it was still a problem. So I added a Newmar Startguard. It's basically a little lead acid battery that holds up the voltage at the electronics when the start causes a drop in voltage everywhere else. Works great on a boat, maybe it has application in these trucks. Or at least use it as a diagnostic tool.

[@brianm9007]

Very interesting diagnosis, Ivan! What's interesting is....say you had a battery tamer on it so the battery didn't die during your service time. This would create your typical battery voltage and the truck would fire up. But then, you could still get a call back as the owner drove it from day to day. If you were constantly in the habit of hooking a battery charger on it from the get-go, you might miss this one! Awesome job, as always!

[@somerandomguy3868]

My 87 hard body started that way for years, it would crank but only start when you let off the key, good to finally know what was happening

[@-DC-]

When I dealt with Nissan the techs would say they are much like a Honda with all the quality removed 🤣, great content 👍.

[@outofthinair1]

Still an excellent case study that lead ultimately to the ECM . If the owner is smart he will take your recommendation and replace the other two cam sensors when the ECM is replaced. If I were him or her, I would not roll the bones on an unreliable vehicle, bite the bullet and fix it. GREAT case study.

[@bradleyforsyth4351]

Ivan, this was a fabulous case study...great troubleshooting. Have a 2008 Pro4X HD that has the same issues. I can put a charger (trickle) on and will start right up...even in cold. I tried turning over with ether with no luck, changed out a new battery...same issue. I inherited this truck from my son (he took my tacoma) and have several electronic issues: rear cargo window would go down but not up and finally traced to a relay. AC/Heater motor has went out 2x. Windows mysteriously go down during the night. I don't drive it more than 4k a year. I don't think Ill ever buy a Titan!!!!!

Microprocessors can be cold-sensitive too. I fixed many instrument clusters that were stone dead on cold mornings. Change the micro, units were good to go.

[@paulschultz2889]

I have the exact same problem on an 07 armada. I have done all the same tests with the same results except the cam position sensor. It has the same reading with the scope where it’s dropping down and the second it flips up it starts right up. The only thing I cannot reproduce is having the signal stay correctly up and not start. I have tried heating up the pcm and it did not seem to make a difference. Other than getting a perfect wave from the cam sensor I’m thinking the same thing that the pcm is bad. Also when scanning it there are no codes. I’m not sure yet if replacing the pcm will fix it but thank you for the video it definitely helped with such a weird diagnosis!

[@paulschultz2889]

“Update” I ordered a replacement pcm from flagship one. A side note on that it came with bent pins and one pushed in. I did get them straightened out and I will have to see how they want to handle that. As far as the pcm goes it does work and fixed the no start when cold. I also replaced all three cam sensors with the 9th revision ones straight from the dealer so hopefully they fixed whatever the issue was with the previous 8 revisions.

[@SerenoOunce]

To test I would pull the fuse to the ECU's ignition feed and feed a separate 12V source to it. If the symptoms are not reproducible after that, a semi ghetto but possible fix may be to add a *super capacitor* bank (~$60 on ebay) to the ignition feed going into the ECU. Splice in the cap bank in parallel with the + feed wire. Use a 10W ~20-30 ohm resistor leading to the cap bank for limiting in-rush current and a couple ~15A schottky diodes (1 after the caps and the other in line directly to the ECU) to limit back feeding to the battery. Finally, add a relay to the Neg of the cap bank, activated by the Pos feed of the Ign wire or the circuit will stay live even after the engine is turned off. May need to leave the key in the Run position a moment before attempting to crank so the caps can charge up. A "Russian" repair for sure but relatively cheap option in contrast to replacing/repairing the ECU. Just use some spade terminals or whatever when doing the wiring so it can easily be restored back to factory if it gets repaired proper down the line.

[@Graham_Wideman]

That would be an interesting experiment! Even just add the ability to power the ECU off a separate car battery as a test. Good idea! That would definiitively determine whether the ECU is going stupid during cranking and reduced B+ voltage.

[@jakeandrus690]

That right there would be a proper Russian repair!

[@oskarbc7213]

I had a similar problem with a ldv maxus van were it won't start unless you jump start it and no one could figure it out. So one day I was looking around the engine bay and noticed there was a piece of rust only about 2 sheets of paper thin between the sensor and the block after giving it a good sand down it started right up. But it didn't have and symptoms of a bad crank sensor, we had rpm and we had a wave form but it turns out the ecu needs a 3 volt peak to peak signal and it was only a 2 volt peak to peak signal so that bit of paper thin rust made all the difference

[@mike_svt93]

I would clean/check the integrity of the ECM connector, wiggle wires monitoring wave pulses and have a can of freeze spray on hand. The diagnosis does however seem to indicate solder connectivity issues or thermal breakdown of an ECM component.

[@samcripes3046]

94 f-50 no start, good crank. Injection pulse 4ms cold replace Ecm long before I knew about loading circuits.

[@jackpatteeuw9244]

IMHO, very few if any ECMs will work properly if the battery voltage drops down to 8.0V during starting. Some where, the power supply in the PCM will re-start the CPU. It takes a few microseconds before the software is running and can fire an injector or spark plug. I have seen on Ford products where on processor (air bag) will have a slightly higher "drop out" voltage. This will give you an air bag warning light, but if you shut the engine off and restart it goes away. This could be similar in that another module is not happy at low voltages even though the ECM is ! (FYI - 30 years ago, in the early days of EFI, there was extra circuitry in some ECMs that would fire the injectors under low voltage conditions before the software "woke up" !)

How to fix a nissan Step 1 take the money you would use for repairs and use it as a down payment for something other than a Nissan. Step 2 sell the Nissan.

[@Mattypeeperz]

Combination meters are a very common issue for cold weather starting issues on Titans. Also, I had a Titan where the ECM calculated voltage was reading ~6v higher than actual. 12v at the battery showed as 18v in the ECM, causing a crank no start. ECM replacement fixed the customer's vehicle.

[@stealthg35infiniti94]

Good job! TIP: The new style of sensors used on Nissan/Infiniti are those round metal looking ones. NEVER buy those aftermarket cheap, 3 sensors for $40. They will fail in a very short time after installation. Avoid counterfeit parts and buy from trusted reliable sources also.

[@markferraro5250]

great stuff Ivan thanks so much

[@adamtrombino106]

That's a good 1! Save those waveforms. I agree that 10v cranking is plenty, even 8 or 9. In my experience only VWs are very sensitive to lower cranking voltage, needing about 9 to 10V + in some models before they will start, regardless of cranking rpm. Should not be so on that Nissan. I also agree, 3 new CMP sensors because you've proven something is going on there and we already know these are high failure prone parts.

[@ericroberts4150]

Have the mysterious no start also,in good weather, modified cat converters show po420 & po430 periodically,but not related to nostart.Cant find wiring issues or in IPDM unit internally.I just clear codes under dash once a week to solve problem for now.

[@100SteveB]

Sounds like a possible bad solder joint to me, they will very often play up in cold conditions - the metal or the board contracts when cold. Could even be a crack in a surface mount capacitor. Not easy to find on a modern smd computer board. One possible way of finding it would be to use some good old freeze spray, freeze certain parts of the board until hopefully you find it.

[@thephantom1492]

I think the sensors are fine. I worked with some wheel sensors recently that was doing that at time. I think it have something to do with residual magnetism in the pickup. Once you get it going fast enought or for long enought the signal revert back to normal.

[@InsideOfMyOwnMind]

Ivan, Recap the ECU. Those ten year old capacitors will fail when cold and work when warm. Classic electrolytic cap failure mode. Recap the ECU. But first look for leakage and corrosion on the board around the caps and check for a fishy odor when you un-solder them. If there is a lot of leakage or some PCB traces are corroded away or blackened then just trash the box. It will never be right again if that happened. In that case even a competent rebuilder will not try to save it.

I'm having a similar problem with a lovely bmw. It sets random codes then its fine for 2 to 3 months. I record the codes after deleting i test drive nothing happened shows. After 3 months different codes same thing. Not to mention the customer said it was a flood car purchase. I dont even know where to start and he refuses to take it elsewhere. I really don't want to take this on because I know its going to be a on going headache Just from the codes. I'm getting no com, shift codes, body codes park assistant codes abs codes. I delete them nothing for 2 to 3 months then more codes. He doesn't have any driveability problems other the he say shifting issue but it's very random. It happens for about 5 mins once every 5 months.

10 year old capacitors in the ecm could be the problem. Old caps cause all sorts of failures. I can fix old computer monitors by just replacing the caps.. Nissan probably bought cheap caps back when these ecms were made.

Kucoal LED Rechargeable Headlamp,2-PACK Waterproof Flashlight Motion Sensor, on Amazon. Look into them, wave your hand in front and it turns on or off. Sweet deal. Not a sponsor. I just see you use headlamps too. Gotta see.

The CEL looks like it’s flickering similarly to how they flicker when the ECM relay fails on some models.

[@awaara24]

I think that could just be the CEL bulb flickering like your dome light would during a crank...

I don't think capacitive touch screen will work with those black gloves.

I would try to recap the computer and reflow whatever solder I could before spending money on a new one.

[@notajp]

Problem is that most ECMs are potted in epoxy now, and nearly impossible to get to the board to do anything......
