Default Starter?

I just want to get confirmation that I'm on the right track before I swap the starter.

Starting yesterday morning, we had intermittent starting issues, which turned into a no start condition after I fixed the problem (so I thought).

The problem that I fixed was the battery lead to the starter was loose (has to be a remnant of my head gasket fix from last year - 15k miles ago), so I tighten it up. Now, no start at all. Brand new battery (it was on the original, so I figure I may as well go ahead a plop a new one in before I *have* to). When I try to start it, it gives a single click. No click click click click.

There is voltage to the starter lead. I swapped the relays around. Is there something else I have overlooked and should try?

Thanks.

Which relays did you swap?

You can also try having somebody turn the key while you bang on the starter with the plastic end of a big screw driver or something similar. Careful, because it could start.

Instead of replacing the starter, you can try replacing the contacts instead (if this is still possible on the 4th gen).

DId you try to short the solenoid input (12V) from the big fat 12V wire fro the battery. I.e. good old fashioned bypass everything to see if the starter will turn over?

See if the solenoid has good voltage when you try to start the truck first.

Also check your ground wires to the engine, their should typically be at least one big fat one form the body to the engine itself. The ground wires are just as important as the 12V side.

As above I would check the contacts on the starter motor first before replacing it all. I assume it is a V6, on a V8 I will just replace it all with new, as it is a PITA to get to the starter.

Thanks for the replies. It is the V6, sorry.

I swapped the starter and dome relays, which I read on here could be done to test the starter relay.

I did bang on it while trying to start it, but nothing.

I haven't pulled the plastic connector on the starter yet. Is there more than one wire there? If so, which one is the correct one to bypass from the battery 12v?

I ordered the cold weather starter (it was cheaper, and possibly beefier?) off of Amazon last night, and it arrived today, so I will just throw the new one on there, if we conclude that it is indeed the starter that is the issue. I don't have to return the core, so I will probably rebuild the old one and keep it as a spare.

The starter does make a single click when trying to start the vehicle. After a few seconds it does a second click. I suppose the second one is the ECU, or whatever controls the auto start, aborting the start attempt.

Thanks again for the replies. I appreciate it.

If I remember right, starters are one of those things that should be kept toyota, but at any rate, it's a good idea to rebuild and keep your existing one.

It does indeed sound like you're on the right track.

Thanks, Robinhood4x4.

The starter I purchased is a Denso (OE) rebuilt starter, so I have good confidence in it.
Here it is for anyone looking - http://www.amazon.com/gp/product/B002SJF6S2

Does anyone know how the engine immobilizer behaves when activated? Does it allow the starter to operate, but kill ignition, or...?

That's a whole new can of worms, but I'll bump your question for you. That might be your problem.

Thanks.

Fortunately, I don't think it is. I was away from home, and the vehicle, last night when I thought of that. When I got home, I tried it, and the light does go off when the key is inserted, thankfully. So, hopefully that is out of the equation.

I'm headed out to swap the starter now.

New one is in, and it starts and runs fine.

When I was removing the old one, I noticed that the end cap had a burn mark on it. So, I removed the end cap and discovered that one of the contacts had rotated, and was shorting out. It must have rotated when I tightened the lead from the battery. D'oh!

Oh well, fixed and back on the road.

R&R of the starter wasn't so bad, for anyone needing to do this. I pulled the starter up between the engine and the fender. I really didn't want to remove the exhaust manifold as the FSM suggests.

Good job on the fix. You're lucky it's not a v8 or you'd of been disassembling most of the motor to get to the starter!

Since UJ asked.

Here's what I saw while removing the starter. At this point, I pretty much knew what had happened.


Here's the rotated contact.


Here's the other one. Good shape.


Here's my new Rubbermaid shop cart that arrived just in time. It was an Amazon gold box special the other day. Got it for ~$50 off the normal price.

Ha, yeah, so I've heard. Hopefully for you V8 guys, the starter is so encapsulated that it will never fail due to environmental reasons.

My sister in law has an '03 V8, so I may have to do that job one day anyway.

Good job on getting the starter done.

How many miles did you have on the truck at the time of failure?

103k. Its failure was my failure, though. The contacts looked like they had a lot of life left in them.
