wont start

i have an 88 supra and it turns over, its gettin fuel, and gettin really good spark. so y could be the problem as to y its not startin.

Turbo or non trubo? Did you check spark to all the cyl? Did check the timming? Did you do a compression test?


Additional things to check: MAF, all intake hoses.

Im getting the same problem, my cars been down for almost 2 months since its hard for me to get over to it now. But what Tcmaboy listed is definitely one of the problems, Im personally thinking no compression. Cause if you turn it over for awhile and then smell around the engine you can smell burnt gas.

its a non turbo. i checked all cyl and they all have spark. but i think that the cat back might be plugged cause i replaced all the vacuum lines one at a time and the timeing is perfect.

Check compression and the maf.

the maf is good but i gotta take the cat back off and see if that works out for me. but thanks for the help and i had it narrowed down but i wanted to make sure first so i would be replacin parts that dont need to be.

Tell me what you find. Im doing my compression tommorow.

im just gonna cut the cat off cause the bolts r way to rusted so im gonna cut the pipe since i need to replace it anyways

check the wires on the cam position sensor, it might have cracks on the wires leading to corrosion, so signal to the ecu is bad, and it wont start at all.

The NA has a distributer. CPS dosen't play a roll.
