View Full Version : ST185 won't start

11-02-2014, 01:53 AM
Hey guys, I'm looking for advice.

My ST185 won't start. It was working perfectly fine and then about an hour later it wouldn't start. When I turn the key there is nothing. I hot wired directly from the positive on the battery to the starter and the starter turns over, however it wouldn't start. So it seems like my problem is somewhere in between.

Looking for your thoughts. Is there a specific relay or fuse that I should be looking at next to solve the problem?

I'd be looking at wiring. I find it hard to believe that the starter signal cut out at the same time as what the car requires to actually fire/keep running without the wiring coming into play. Unless your fuse box is just gone or something. Seems like there's a lot going on all at once.

This is gonna sound odd, but check your ground on the battery. Ive seen this before, where it seems everything is ok, but the ground isnt good enough.

Or the park/neutral safety switch if its an auto. try snugging the stick up to be sure it's all the way into park, or just shift to neutral.

^It's a ST185, an All Trac. No automatic there.

Yeah you saw it on my car last year before I replaced the cable ends. :D

O I thought it was the old one he's got pics of in his gallery. If its a manual you still have a clutch switch in series with the whole starter circuit, if that thing is not closing you won't even here a click or a buzz.
But I'll agree to check the battery terminals and grounds too.

Thanks guys for the tips. I've been super busy with work lately and haven't had much time to look at the car.

I did take the dash apart and start looking at wiring, and was unhappy to see the previous owner had done some butchering of the wires. There are so many wires that were spliced in and just hanging there with bare ends. I don't even know all the things that must have been tied in. There is even spliced wires under the door sills that lead to nowhere.

I'm guessing that this is where my problem is. I might be needing to do an extensive rewiring project on this one. I guess that is why it is my project car, unfortunately it takes time away from working on my 205.

I have also had my all trac magically start after adding a engine ground strap. It was after I first got the car and was working out various issues.

If not does the CEL come on when you turn the key? If not check this thread, happend to me in like March or May this year. http://www.celicatech.com/forums/showthread.php?58473-94-Celica-GT-cheapest-and-longest-fix-ever&p=30237113&highlight=#post30237113

Check your efi fuse. So it's cranking just won't fire?

while the car may need a lot of wiring attention, I wouldn't go rooting around in all that until you've solved this current issue. you are opening up a can of worms that might make finding this issue even harder. I doubt the hack job under the hood is related unless something grounded out and shorted a fuse, in which case Id be checking all the main fuses. Start with the simple stuff, efi fuse, main alternator fuse, etc. Then use a multimeter to start tracing power from the battery through the fuse block and ultimately through the ignition switch.
