Default 100 no start, then it did....

So a couple of months ago I go out to my 100 at lunch and it won't start. Starter works fine, just won't catch. I think it might be low on gas, and a couple of hours later I call AAA and go down to the truck to wait...and when I try and start it, it starts instantly, no problem. Last couple of months, no issues, then last night I run to Safeway and when I come out, again no start. Same issues, just filled the tank from 3/4 full a couple of days ago. I walk home (only 1.5 miles, and I was still in gym gear, shorts and sweatshirt!) and walk back a couple hours later, still no start. Call AAA to tow home. At midnight the tow truck driver calls and says he is 5 minutes out. I put the truck in neutral for the tow, and quick try to start it one more time...and of course it starts! It also started just fine this morning.

I was leaning towards the fuel filter, but that doesn't make any sense to me any more....maybe fuel pump? Unfortunately I just don't have the time to deal with it right now myself, so any good Toyota shops in SE Denver?

Thanks all!

I would lean towards the starter. The symptoms vary a bit from rig to rig, but the description sounds very similar to what is experienced when it goes bad. I've had to replace the starter on mine twice in the 12 years I've owned it. First time I had a shop do it and last time I did it in my garage. It is your choice as to whether you replace the contacts (way less dollars) or put a new one in. Either way, the labor takes some time as you have to remove the intake manifold to get to the starter.

Wow, really? My experience with bad starters has been they just don't do anything. But that was with 40's and I think my 80. So the starter can sound like it is working fine, but it ain't puttin out da juice? (sorry...I need a nap)

Probably worth putting in a new one...and will have to farm the work out. Yay.

Thanks Ricardo!

I had a similar issue one time with my 40. But it was a simple battery corrosion problem. If I jiggled my battery cables around or cleaned the terminals, the problem would go away for a while. Then, a few months later it would happen again.

Strange.....so had anyone else experienced this with a 100....the starter engages and fires and sounds totally normal, but it does not start. That sounds more like a fuel problem to me...I am looking on MUD right now and see a lot of cases where it clicks or is dead, but none where it fires normally. I would hate to spend $500 to put a new one in if it is fine, for now. It does have 160k on it.

Thanks all!

Tim

Steve that was my first thought, especially after reading Robbie's last column. My key actually did crack recently, but after the first time it would not start. I took the key apart, and it was just the plastic around the metal key, everything else is fine...and my backup key did not work either.

Is there some sort of timer failsafe that prevents the truck from starting for a couple of hours after a non-correct key is used?? Confused as to why it started just fine a few hour later each time....

thanks all!

Sounds electrical so me. Maybe next time it does it have a hammer ready and smack the starter or the bottom of the tank for the fuel pump (if that where it is. dont know much about the 100 sorry) and try again. Smacking the tank make sure you hit the fuel pump. Have had a few pumps go and that is how I found out. Just a thought.

Do the 100 series have a fuel pump relay? The fuel pump relay on my LX went out but thanks to Romer and him telling me about once, it was a simple 5 min swap (if that) and the truck started fine. Same symptoms as Timm is experiencing...Starter engages but no start.

Going back to lurking mode

Mine did that
Apparently some have problems with the throttle position sensor
Next time it happens unhook the battery then hook it back up and see if it cranks right up

Usually there is a check engine light

Mine had the light and I pulled a code for the throttle poison sensor
