1990 Toyota 4Runner - "No Crank" Issue Resolved!

[@JesusChristson]

Love the simplicity of the Toyota 4runner

[@kevinsalguero1357]

I did this after gettin the click no crank symptoms after installing a reman denso starter while doing head gaskets on my 91 t4r 3.0 4wd. Installed and wired up new ford starter solenoid with new battery cables , and battery . Only happens when warm. I did it when it was winter and started happenning once spring/summer hit. Starts up everytime on cold start ups.

My '90 Runner has an issue where it cranks for a solid 30 seconds and then it will start. I've done a cold start injector, coolant temp sensor, and still have the same issue. Any suggestions of where to go from here?

[@joetrueblood7663]

I had similar issues, it turned out my fuel pump bracket had pin holes in the steel tube so gas wouldn't get the right amount of pressure.

[@frijoleramirez7283]

@joetrueblood7663 Just curious how you figured that out? I assume you did a fuel pressure check, but how did you pinpoint the pin holes?

[@RReg1388]

I too am having 1991 3.0 issues also. I can hear the start whining. A lightly whining noise but doesn’t turn over. What can be the issue?

[@ThunderBear4WD]

Difficult to say without taking a look at it directly. Lots of things to check. Lots of voltages to check.

Thanks for the vid, nice work. So in the end, the relay you found under the glove box, you disconnected that from the starter and added your own under the hood it looks like. Just want to confirm that the relay under the glove box was in fact connected to the starter, and that's where you pulled the ignition signal off of up to your new relay? Do you think it would have also been possible to keep the original relay under the glove box, and run a nice fat wire off the battery terminal directly down to that relay, bypassing the original black/white wire that sourced the relay? Thanks

[@ThunderBear4WD]

The relay under the dash was left in place. The wire that went to the solenoid on the starter was redirected to engage the added relay. The added relay, when activated, is now sending full voltage down to the solenoid on the starter.

[@mikew8437]

@@ThunderBear4WD I see thanks...in your earlier comments in the vid you had said in the parts list you couldn't find an obvious starter relay...so that wire to the starter that you redirected to your new relay, where was that wire coming from originally? Thanks again

[@timjones6413]

So is there on 2 wires being connected to new relay the black and white wire from old starter relay and one to battery

[@cdcorrigan]

So the problem lies somewhere between the key switch and the relay?

[@ThunderBear4WD]

That would be correct. So, I identified a work around. I've learned since, that this is a common and repeatable failure. Because none of them indicated an actual solution to the original problem, many other people chose the same solution. At the end of the day, it worked and that's all that mattered to us.

[@cdcorrigan]

Must be a worn out key switch

[@worldclassish]

I have a 95 with a no crank no start so this was helpful thanks.

[@jesseserrano6520]

Hi friend haha So i have a 96' 3.4 v6 I also trying to troubleshoot a no crank no start. I've installed a new starter it's got power just reeded my grounds. The relay the ignition switch Still nothing. What did you end up figuring out??

[@1akradman]

Did you figure out this problem? I have a 95 4 runner and I'm trouble shooting the same problem and found today that the wire connecting to the starter solinoid is only getting 8 volts and rings out to the ground leading me to belive that these 2nd gens have a common problem with that wire. It is the black wire with a yellow stripe that plugs into the solinoid. I'm going to cut the plug and solder it to a new wire.

[@ThunderBear4WD]

I put a relay in place to send a full 12V to the starter, using the solenoid wire to trigger the relay.

[@katielaffranchi4796]

Your definitely not old or lazy!! Work smarter not harder!!

[@alexsmith5797]

Took the words right outta my mouth lol

[@twwarrior1669]

Where the relay locate on my Toyota 100

[@ThunderBear4WD]

Not sure

[@zakklee2556]

Dual starter relays.

[@Killthebatsman]

I have a fun problem… I have a ‘92 4runner. Battery reads 12.4V but I have no lights, no power whatsoever… When I turn the ignition absolutely nothing as if the battery is fully dead. Got to work in the morning, wouldn’t start end of day (came back in the evening with a jumper box and found the battery was 12.4v so needless to say battery isn’t an issue)

[@ThunderBear4WD]

Sounds like a conundrum wrapped in an enigma.

[@Killthebatsman]

Yeah got any ideas?!

[@ThunderBear4WD]

​@@Killthebatsman I'm not a huge Toyota expert, but I'd start with how clean the battery terminals are. How your main cables terminate, is the ground good to the engine and the chassis. Does the main power supply wire have something like a fusible link that's blown. Check all fuses and relays. Get a test light or a logic probe and see what's hot and what's not. In general check the condition of wiring harnesses. Look for damage, burned wires, shorts, etc... Check power at the key switch, see if there is battery power coming into it, and back track to find the fault if there isn't. Basically, systematically eliminate known good wiring from potential bad wiring. It's not necessarily fun or easy, it's certainly time consuming. Keep track of the things you've proven to be in good condition and keep chasing until you find the issue. Start at the battery and work your way out from there. Take your time, try not to become frustrated, take plenty of notes. Once you find potential issues, repair as required and continue on. If you're in over your head, admit it and take it to a qualified mechanic.

I cut little pieces of paper between the contacts on the relay then it worked.

[@randallpool7388]

Yay!

[@rubbertire6608]

You want to buy my 4 runner

[@ThunderBear4WD]

Even though we have a fair number of Toyota videos, they've all been for Keith's 4Runner. I'm personally more a Jeep freak. Beyond that I love Blazers, Ramchargers, and Scouts!
