ok so ive been having code 11 come up im not sure where to even start tsrm dont list a code 11. i dont know if this is related or not but i was running 14* of timing and well my car decided it didnt want to start again after i had a friend show up with tools i rotated the disbruter till it started could that be causing that code to come up? any help would be greatly apprectied. other then that one time not starting it drives fine i drove close to 300 miles in it thursday with no problems

Code 11 is interrupted power to the ECU. Check your ECU grounds - they should be bolted to the lower intake manifold near the firewall.

i did check that they are on there good and clean. that was one of the first things i had checked when it wouldnt restart

ok so i got on mitchell and it said to check voltage between e1 - (batt, igsw, mrel, +b1(+b)) i had voltage to all of that so i dont understand why im getting code 11. so i got on identifix and they basically said check throttle plate for carbon build up well its clean. so i was wondering if a bad tps could be causing it i did get off ebay a year ago. im starting to have running issues where it dont want to start to well and i have to hold my foot to the floor to get it started sometimes and sometimes it dont always work, and if i am coming up to a stop it will stall out and i just pop the clutch and it restarts but ill have to hold my foot on the gas so it dont stall back out.
basically what it sounds like is that its giving it to much advanced timing, i could just retard the timing to prevent it but its still not solving the issue woth something being defective

Anyone got a good lead?

Reset the mechanical timing to stock and see what happens. Also, never just check your grounds. If a ground is even remotely suspect, remove it, clean it and it's mating surface with sandpaper, and reattach it. After that try checking sensors. There are steps for testing both the TPS and the AFM in the TSRM which can be found here: http://www.cygnusx1.net/Supra/Library/TSRM/MK3/manual.aspx?S=FI&P=1

well i had reset me timing to factory. did find out why it was not wanting to start the tps sensor is bad i have to un plug it to start the car. i just had the engine out and rebuilt so i knew the grounds were clean just thought they may have came loose but they had still were tight. i also found that if it has extended cranking (more then 8 seconds it will set code 11.) so with the tps acting up thats my guess to why it was setting that code.

And you have a 20 year or older car. Entropy, learn it.
