No-Start rears its ugly head. Saga continues. Sleuth(s) still needed.

Because I like to fantasize about easy fixes.
























:rolleyes: (Wouldn't that be nice!)
No, really, it's because mine is NOT clicking at all and because I pressure washed the undercarriage recently and had some short term issues afterwards. This problem started at nearly the same time. ALTHOUGH....now that I think on it more, I had a shop do some front end work for me and change my belts while they were in working on it. They easily could have bumped something, loosened something on the starter at the same time. I'll have to start my investigation on Saturday.

Here's the real trick though, wire up the momentary switch from battery pos. to starter solenoid semi-permanent and use a seperate lead for troubleshooting. That way as you're troubleshooting you don't get STUCK! It's easy. I ended up wiring a marine protected momentary switch in the engine bay permanently.

Tiorio,
Can you post more details on this? Do you have pics or a diagram? Sorry, I am electrically impaired and not visualizing this. Thanks!
 
Intermittent starts are back. Boo.
 
I'm struggling with a start isuue as well. I am about to order contacts from Dan and change those out but I think I may have a variety of stuff happening.
- 2 years ago a local bonehead mechanic was to change the contacts, while servicing the alarm went of and as he couldnt get it to shut down he 'pulled a few wires'since then I would get an occasional spate of mystery door locking and unlocking and rare no start
- recently the no start has gone form a occasional nuisance to a frequent pain.
-Sometimes I think I can hear the starter spinning? but no start?
-Sometimes when I wiggle the key ( technical term) it will start.
- All electrical functions normally

Have you checked the connector for the Neutral Safety Switch? On a 94 with the A442F transmission the connector is not on the NSS, it is slightly "upstream" of it on the driver's side. IIRC there are two separate plugs, one with the small pins that light up the shifter position indicators on the dash, and one with two larger gauge wires that bring the signal in from the ignition switch to the NSS and then out from the NSS to the starter solenoid. If either/both of these larger pins are corroded/torn/broken it would cause the symptoms you are having (it did on my 96).
 
Awesome! we are in the middle of a major snow storm! 2 feet in the last 24 hours here in the canadian rockies!
My truck is a 97, would the neutral safety switch be in the same spot as the 94? and is there a bypass for the switch or do i jst clean the switch contacts and go with that?

Cheers peter

For the 95-97 trucks with the A343F transmission, there is some good info and photos in the threads below. The same principals apply to the earlier transmission (A442F) but the connector is different.

Adam, thank you very much, i will have a look at this friday and see if this is involved in my troubles or not.

Screw this s***. I've checked everything, and it's all ended up, in essence, as temporary fixes. This intermittent BS keeps coming back. The wiring in my rig is just old and the ignition switch can't handle the current to activate the starter solenoid. This weekend, I plan to install a relay to the small black wire that activates the starter. This should take care of any current limiting BS in the stock wiring. My woes shall be vanquished!

Why don't you just wire in a push button start? Turn the ignition key to on, push button, drive. Just a thought...
 
Or at least list out what you've already done to see if there are any other ideas. Many of us have gone through this and it's possible that not all solutions are contained in this thread.

I've done it all :) Tired of chasing this one.
 
I was having an intermittent start issue and suspected the aftermarket remote start system, so I removed it as it was an older unit the previous owner had installed. While under the dash I noticed a lot of other non-factory installed wiring. I followed the bundles and it turned out to be the 'Toyota VIP security system'. It was tied into everything, had a loom that bypassed the ignition, and had two modules, one under the drivers seat and one up in the drivers foot well. I removed the whole system (which was a bit involved), but I haven't seen the intermittent start since. I'll report back if it returns.

Note- I'm still debating installing a hidden momentary switch as an 'emergency' start button just in case the problem returns. It would have to be a direct (battery-> fuse-> switch->starter) type system that completely bypasses the factory ignition. With a switch like this-

Ron,

I feel your pain. I was having the same issues so I replaced the ignition switch to no avail. That was truly a PITA for me. I much prefer to drop the starter motor than having to deal with that switch again.

So I sucked it up and opened up the starter to check the contacts. Sure enough, the contacts were not flat and lots of signs of bad connection (pitting). Took them out, filed them and re-installed them per FSM using the press this time. The problem got solved instantly. Mind you, this is the second time I re-seated/sanded the contacts but the first time was done using a press. Last time, I used a 8" vice so I'm hoping all will be well for now.

Good luck with your hunt.
 
Can't wait to get the relay in!
 
Installed the relay earlier today. Started like a charm, but I'll give it a real test tomorrow. The "no starts" usually happen when the engine compartment is hot. If my theory stands correct, the starter circuit wiring from the ignition switch is just plain old. The wiring junctions have added enough resistance and subsequent voltage drops that the voltage at the starter is not enough to activate the solenoid. Heat just exacerbates the problem in my rig. I cant speak for anyone else's vehicle, just mine. I've been wrong before, but this will likely have solved my problem. We'll see.

speaking to someone about a very similar situation just the other day and his diagnosis was spot on with yours. :wrench:
