Intermittent starting problem

10

Asked by hugmar Jul 21, 2015 at 02:48 PM about the 1988 Toyota Pickup 2 Dr SR5 4WD Extended Cab SB

Question type: Maintenance & Repair

I have an intermittent problem (Electrical) with starting, hot or cold does not affect this. I have replaced starter, both starting relays, ignition switch (Electrical portion), battery (It was due), and replaced a section of wiring from relay to starter solenoid in engine compartment. Started immediately for about 2 months, now problem has returned.

I had the same issue with my '89 pickup. Would drive it some place, get back in, and nothing. No click or anything. Let it sit for a while and bang, it would start. I believe the issue is the distributor. I never really went to the trouble of figuring it out. I just installed a push button under the dash and ran a hot wire from the battery to the button and then I spliced into the ignition wire and ran that to the push button. If the truck refused to start, I would just hit the push button and it would start every time without fail. I just figured the truck was so old, why bother sinking a ton of money into it?

Thanks reelin68, this is to be my last resort fix. I did some more diagnostics and found the hot wire from ignition switch to starter relay has some resistance somewhere in the line, so I cut both ends, one at the switch connector, the other at the relay plug and spliced in a #10 wire. This showed no resistance after retesting, so hopefully this is the answer. If not I will take your advice and install a remote switch. Now when you installed this, can you start from both key and remote?

Yes, if key fails, just hit the push button.

I am experiencing some starting (electrical) problems as well. Hugmar mentioned two starter relays. Where are these located? I would be up to wiring in a push button switch, but uncertain which wires to splice into. Can anyone shed some light on the subject.

Brad, if you are having an intermittent start issue, it wouldn't be a relay issue. Once they fry, you won't be able to start the truck. Not to say it can't be loose. Look under the hood by the battery. Should be a black box on the drivers side. Open it up and look at the schematic under the cover. What exactly are your symptoms?

I would suggest checking the crankshaft positioning sensor. That was the problem with my wife’s car. Replacing it was the answer.
