So it seems to fix its self?

[rs4rush]

So about a week ago I started my car to go to work, it started and I let it warm up for about five min. Next drove to work everything was fine, parked it and shut it off. Next after work was done I went to start it and bammm wouldnt start, it would crank but wouldnt start. I checked my battery, spark, fuel, starter...... and cables/vaccume hoses. And it all checked out. So then I spent 80 bucks to tow my car to work (toyota) and then got it written up and I was going to have a friend look at it. So the next day I get a phone call, "cory I just walked out to your car and it started right up." But for two days it wouldnt start for me? I think it might be my ignitor?? Any ideas? But now for about a week it runs fine....?

Must be nice to have one of supras that fix thereselves, I need one of those .

Are you getting any error codes?

 

[rs4rush]

Nope. It wasnt throwing codes.

probibly the cps. next time it wont start hop out and wiggle the wires and try to start it again. mine does the same thing from time to time.

Was it cranking at full speed? Or did it seem sluggish when it wouldn't start?

 

[bigaaron]

Next time it will not start, try jumpering the fp to b+ in the check connector and see if it starts. Usually it is the cps connector though.

It fixes itself till it leaves you stranded on the side of the highway.

Sounds like a possible intermittant alarm malfunction.

I had the same problem.Was a fucking nuisance.

I would go to the mall and other places it wouldnt start.The worst time it happened was in the envening and it was pouring down really hard. I was all wet drying to fix my supra in the rain.

I had to tow the car 4 times on different occasions.

I got fed up and connected a wire to the signal wire that goes to the starter. I connected this to the switch under my dash. Everytime it wouldnt start I used the switch.

I think it had something to do with the factory alarm. I unplugged the factory alarm harness and there was water. I have not idea how it got there but I cleaned and dried it.

The problem was solved.

Same problem here too; it would seemingly start at random, but mostly just sat there and cranked.
Turns out 2 of my injector clips were loose.
My car sat for 3 days while I tried to figure it out..... and everything checked out fine. Finally pushed the clips back into the socket, and the car started fine.

 

[supraman7mgte]

the thelman wire is corroded,replace the motor...na,check the cps

 

[csolstad]

cps wires.. it would crank and crank but it would cough/chug sometimes like it was trying to start

 

[SDtoyomk3]

maybe the start relay?

 

[starscream5000]

If it's cranking, but not starting, then it's not in the factory alarm. Once the factory alarm trips and you try to turn it over, it will do squat.

 

[rs4rush]

Ya mine turned over fine but no fire. I will check the cps.


Gotta love supras!

I fought with this very same issue with My car for months. It was none of the above responces. Strangly enough my car was flooding. Every once in a while when it would do this if I immediately put the pedal to the floor while cranking I could get it to fire. But if I failed that attempt then it wouldnt start until the next day. I discovered that if I unplugged a couple of my injectors and cranked it would fire after a few turns and then I just plugged the injectors back in.

I was never able to solve this problem but it has since not returned since I did whole rebuild. It was possibly due to leaky injectors, a bad pump relay or a defective injector resistor. All of those parts were replaced during my build.

next time your car does it, you could try my "quick fix" and see if you have a sililiar issue.

Thats right....I'd say check your cps and throttle postion sensor.

Years back I had a faulty tps and my car would crank but not start.
Then I opened the throttle and it started. I changed the tps and it started without me having to open the throttle.

I think my bronco has a bad tps then too, because sometimes I have to hit the gas (usually in the heat of day or when it gets driven) to start it, but in mornings it always starts right up.

Question: Can a bad TPS cause you to not idle whatsoever? If I hold the gas it runs fine, but the second i completely let off, it just dies instantly.
