Supra won't start!!!!!!!!

Yes he was correct when he said check B+ and Fp on the diagnostic box. Just take a wired and connect the two. If you hear the fuel pump relay make a sound (other side of the engine compartment) and fuel goes through the system, your pump is good.

Things that have to do with that system are the EFI relay (the grey round one on the top right of the junction box i believe) and the EFI fuse (bottom left 15 amp i think). If you still are not getting fuel with all of those things working then get back to me... cuz ive had the hardest EFI system trouble the last few weeks and could tell you almost anything about that system.

Also, pull out a spark plug, plug it into its case... spark plug wire or whatever its call, lol. Then hold it to the engine block while you crank the engine. You should see a spark on the end of the spark plug, if not your problem is in the ignition system.

Hope this helps!

Hi Guys, Just wanted to follow up with some info that helped me get to the end of the problem and got it fixed. I checked all the fuses...........under the hood and in the drivers kick panel ALOT of them were blown............. replaced all of the bad ones ofcourse. Got a tester and checked for both fuel and spark which even after replacing all the fuses and checking the igniter/coil neither was working. So..................looked at a wiring diagram for the car and the unit that controls both of those functions IS............... The PCM! I went into the dash pulled the glove box out and right up above there it is.Took it out [3 connector bundles and 3 screws]and copied the info off the module. I got lucky and I found a exact replacement right down to the last letter and number...........made sure it was MT for manual tranny and bought it for $125.00 at a local salvage yard...........they kept the brain, the Supra it belonged to was long since crushed. ;( Got home plugged the 3 connectors back in to the New/Used PCM unit then remounted it to the under side of the dash,put the glove box assembly back together and.................turned the key VAROOOOOOOOOOM! Back to life! Runs and operates just as before. : ) Hope this helps someone else down the road.................... but the best thing to do is when your getting mother SUPRA back to go out on the road after a long winter nap make sure you don't have her wires crossed [like on the battery!] I got really lucky that this mistake didn't fry the car or alot of other expensive parts.Lesson learned! I''ll be VERY careful from now on............it a great car that I don't want to lose.
