Diagnose No Crank No Start Like a ROCKSTAR with Bonus Track!!

Diagnosing a 2007 Lexus RX330 with a no start from a fairly famous owner- car will not even crank, starter won't even click. Seems it may not be a starter issue but more a control or power issue to the relay.
Also we catch up on some other cases and see how they are doing, plus a major update on the Schrodinger's Box Book by Dr. Ayman Kamar.

Sugarloaf "Don't call us" -- totally remember that tune fondly from the 70's! It's the song that uses the main guitar riff from the Beatles "I feel fine", which I also liked! (And it's a fun diversion to hunt around for other songs that are loosely based on the same riff.)

[@SchrodingersBox]

Matt, I can't thank you, Eric O at South Main Auto, and Ivan at Pine Hollow Auto Diagnostics enough. I have been watching all your channels for quite some time now. Along with Richard at Precision Transmissions. Since watching I have rebuilt 2 transmissions successfully. And I have learned so much about diagnostics. I purchased the Xtool D7 along with many other diagnostic tools that you guys use on a daily basis, hoping that one day I would be able to use them. The Xtool D7 sat on my desk until my neighbour was telling me that see had lost her key fob and had to tow the vehicle 100 miles into the city and a fee of $250 to program the fob. I piped up and said " I think that I can do that for you" she was surprised. Sure enough the D7 had a key relearn feature and what do you know it WORKED!! I has a hero and she was so happy!! She saved a ton of money and gave me $100 bucks. My first earnings for a diagnostic/programming job!! I am so stoked. Give me a check engine light and let me at it! Thanks so much guys!! Fist Pump!!

Great job, Thanks for sharing! I know from your other videos that you will try to figure things out without a diagram, I feel that on today's cars, it's just not really feasible to remember all the quirks of each car. I always look at a diagram from the beginning. Keep up the great work!

[@SchrodingersBox]

Great observation!!!! yes you are correct. I used to just figure it out but you are right- more and more I am finding that the newer the car, the worse that strategy works lol. also, there are some designs now where if you do the old methods of “let me bypass this” or “let me put voltage to this” it can actually cause major damage because the circuits aren’t what you expect!!!

[@NathanSmith-ut4ur]

From the brief googling I did, the Lexus RX 330 shares the 2GR-FE engine with the RAV4 of the same year. I just did that in my girlfriends RAV4 and it really is a proper pain to get to the starter motor. You have to take the whole battery tray out and then the gap is super tight to get the motor in. I got an aftermarket starter on rock auto and it was a smidge longer than the OEM which makes it super tight with the transmission mount. If that thing fails again on me it’s going to be a nightmare to get back out. Another great video Matt! It’s so great to see the community you have following your channel.

[@reneneron2971]

It seems a bit strange, but wiring the starter relay that way ensures the ECU controls starting the vehicle. This includes the immobilizer (validates correct key is present), remote start capabilities, and the ability to not allow the car to attempt to start if certain conditions are not met. Also remember on a push start vehicle it is necessary as the ECU controls how long the starter is activated, and will shut off the starter if a no start condition happens after cranking for a short period of time. Otherwise the engine would continue to crank continually even if it did not start for another reason (no fuel, bad ignition, etc). Clever, yes?

[@SchrodingersBox]

Oh I totally agree- my question is why doesn’t it do it by controlling the ground side of the control though?

[@reneneron2971]

@@SchrodingersBox I am not an automotive engineer, but I suspect that a control wire fault is much more likely to short to ground than coming into contact with another 12v source. Doing so would engage the starter provided that the ignition is on, even with the engine already running.

[@SchrodingersBox]

Would seem to me with a push button start the PCM would not engage starter with an active CKPS signal though. I’d rather have ground fault than a blown PCM for sure!

What was the final fix? Starter motor or starter solenoid? And what were you doing with the long screw driver when it finally did turn over with the power probe at 24:20. Jumping the solenoid? Could you jump the solenoid with a screwdriver without the power probe sending power? Or had to do both?

[@MrsSunshine75]

@williambarnett I’m super confused on that also?

[@jimbeckettplay]

Make sure you remember to change the No Crank, No Start in the book, too! I'm not arguing with your assessment, nor the outcome, but I missed how you proved that the cause of the starter issue was not ground related. I can envision those seats and steering wheel moving with a so-so ground that might not be adequate to crank the engine. Ground cables and corrosion would have been my starting place to investigate - solely based on prior experience of instrument cluster behavior caused by ground issues in ancient Chrysler products, and other clap-trap automobiles.

[@SchrodingersBox]

Hahaha yes I will do that but probably mention it in the book why it’s just no-crank! Ground is not an issue on this starter because the block is the ground. No ground cable.

[@jimbeckettplay]

@@SchrodingersBox It took a few minutes for it to sink in, but you proved the ground cable was not the issue when you changed the starter. (Since it worked properly, then.) I was thinking in terms of positively condemning the starter prior to changing it. If you were able to do that 100% before attempting the new starter, please explain to this dummy how... hehe.

[@calholli]

I couldn't really see the diagram, but I would bet that the ignition switch actually turns on a larger main relay that the turns on several other things, including the load side at the start relay. I wouldn't think that they would wire the ignition switch directly to the starter solenoid. I bet there's more fuses and relays under the dash. It's still pretty odd though.. I'll have to remember this one. I think this is the first time I've seen something different than the normal constant power there at the starter relay; I would have definitely thought there were issues there until I seen the wiring diagram. interesting.

[@SchrodingersBox]

yes I actually simplified the diagram a bit however the start position does indeed send 12V directly to the load side starter relay. reminded of 1950’s Buick I worked on recently. you are correct in that there are other offshoots from ignition switch to the ECM of course but it is a direct bee-line to that relay! I think it’s “safe” because the relay does the ground side completion afterwards so the switching is inside the relay vs the ignition switch.

[@cruzramirez33]

Good videos 😮 one question.. when you disconnect a sensor and check for power and ground and signal at the conector and it checked out good .. after you connected it back and you back probe with the key on and you don’t have the same reading.. does that mean you have a bad sensor??

[@SchrodingersBox]

No it means the switch for the sensor is open. On an open you will see the votage on both sides of the circuit. If you have amperage through the circuit then of course you will se the voltage drop across the load.

[@bradbeck2601]

Seems like the relay is set up like that to eliminate accidental double cranking the engine? ECM won't send power to the relay control if it sees the engine running. Still seems a bit of an odd setup for a car but I typically work on older heavy trucks and construction equipment.

[@HOTRODRICO]

the lexus fuel pump has its own ecu module and even getting the starter to turn the engine on wont start the car because the rest of the main ecu functions (throttle position sensor, injectors, fuel pump etc) are not being activated, they all work simultaneously, so just the starter cranking isn't gonna make the rest of the components necessary to start the car activate... peace

Hi Matt. Please help. My car does crank and every sensor is good according to the scanner, but yet there's no spark. What could be the problem.... it's a corsaD z14 XEP engen

[@carlodonnell146]

Hi Matt, Is it easier to fry the ECM with a POWER-SIDE switched system, than it is with a GROUND-SIDE switched, or is it equally the same?

[@SchrodingersBox]

Same. The difference with ground side is that it’s much safer for PCM if there is a wiring fault. If PCM provides power and that wire grounds out, you fry the PCM. But if PCM provides ground and the wire grounds out, you don’t blow the PCM but of course that device would always run.

[@TylerDurden-pk5km]

@@SchrodingersBox I would assume that the PCM will have current limiting by whatever means ... fuse. resistor (cheapest option), polyfuse or as part of the voltage regulator for the circuit ... that would be just common sense.

[@SchrodingersBox]

It often doesn’t!!! That’s the thing!!! A fuse in the circuit won’t help on a positive side PCM control because the transistor in the PCM would blow long before a fuse did. You want that fuse to be directly from battery source and PCM controls ground after the load so in event of a short on that power, PCM will be saved if it’s not switching at the time. Take a fuel injector for example- it has a fuse. And it’s ground side controlled by PCM. If you ground that power out in front of the injector- then no matter what you won’t hurt the PCM. You will just blow the fuse. If your ground wire on the injector grounds out, again, you won’t hurt the PCM (but injector would always be open). HOWEVER- if the injector itself shorts or you short across it with a paper clip, you will blow the PCM, the fuse won’t even blow because the PCM will fry long before the fuse would.

[@TylerDurden-pk5km]

@@SchrodingersBox I am not an expert on ECU design - and if there is no protection circuity and only a fuse - you are right, it will likely kill the transistor. Though I cant imagine that modern ICU do not have protection against it - for example combining a current limiting resistor and a a fuse (or PTC). Or implementing a current limiter that switches off the transistor in case of overcurrent - it wouldn't really take much to implement something like it. Modern phones, computers, chargers are full of power electronics creating numerous voltage rails - almost always current limited. Could be an interesting test on a car that's headed for the scrap heap. e.g.: US patent US20140347774A1 descibes a sophisticated approach - but much simpler approaches would use a similar setup (just without the staging and the need for an ADC - just simple comparators).

[@carlodonnell146]

@@SchrodingersBox So is that same thing as installing a fuse between the PCM and any device; the driver would still blow and not the fuse. even if the fuse was 5amps or smaller?

This is a timely video. I'm currently diagnosing a starting issue on a 2006 Mercedes-Benz W203 220 CDI. The starter has 3 fuses and they're all fine. I've bypassed the relay and put power and I've been able to get the car to start. It is now an intermittent start. Sometimes it will start on the button but most of the time I can hear the solenoid click so I'm ruling out the electicals from the ignition switch to the solenoid connection so I'm suspecting a bad connection to the solenoid or the starter itself.

Hey Matt I have a 2003 GMC Sonoma 4.3 I have a PO 351 any help on what to check would be greatly appreciated

[@SchrodingersBox]

I would swap the coil, plug and wire with adjacent cylinders and see if code changes to one of the new cylinders. If it does, that part you moved is bad. If code remains you need to check your coil reference voltage, signal input and ground.

[@johnnyfivealiveable]

Yeah it has all new wires,coil, rotor and cap that was put on it from a shop

[@johnnyfivealiveable]

But thanks as always brother you rock

[@SchrodingersBox]

Yep in that case there is a missing input. Or signal.

[@jimbeckettplay]

@@johnnyfivealiveable That doesn't mean that all the new parts function correctly. Take his advice and move each to a different cylinder and see if the problem moves.

Sugarloaf, not Steppenwolf (brain apparently stuck in the 70's)

[@SchrodingersBox]

You just have had a great time in the 70’s lol. Steppenwolf one of my favorites- and my favorite song is indeed magic carpet ride. The 8 minute psychedelic version- not the radio version!!!

You should look up the proper usage of "begging the question". I know that a lot of youtubers (and others) are using "begs the question" as a replacement for 'raises the question' but that's not at all the proper context for that phrase. Hint: theres really no reason normal (and intelligent) people like us would ever have a need to use that phrase in normal conversation. Its a logic thing. Like philosophy and what not. I can't really even explain it effectively which is why i suggest looking it up right here on the toob. Ur welcome. ;) If you happen to be using the word "efficacy" in any capacity, thats pretty much a similar situation. Its very specific and lots of people are using it without looking it up. Context doesnt define anything.

I literally have no idea what you are talking about. The irony that you are trying to help me communicate better hahahahahahaya

What was your thought on the data interpretation from the diagnostic. What would you have done differently?

[@hobofoshitsho8999]

@@SchrodingersBox 14:45 is where you said it. Your diagnostics skills are far superior to mine. I have no input on your technical skills. Looks like you're on point to me.

@@SchrodingersBox I'm just poking around for ideas. I'm dealing with a 2013. Yeah, sportage, it was idling a little rough and seemed like it ran out of gas in the driveway. I put five gallons in it and now it won't start. It's basically a crank, no start. But I did get it to fire a little bit with some starting fluid. Oh also, a door was left cracked which killed the battery while sitting for 2 days. Charging the battery currently (pardon the pun) any suggestions?

What data do you have?

@@SchrodingersBox actually, I just confirmed it was a fuel pump. It's on order.

did i miss something i thought the purpose of the relay was to carry the load. unless i missed or misunderstood appears the switch is carrying the load it just goes thru the relay the relay just breaks the circuit seems like a waste of a relay.

[@samstvshow]

Cheap sht cars. It became law that starters be controlled by a relay. These guys and others obeyed the law but entirely missed the point : they still route mains power through the ignition switch.

Matt, you rock brother as always thanks for sharing.
