Check to make sure the coil packs are grounded well. when i took mine apart the ground wire was half way decentagrated and the wire was bare. im sure it was causing some of the problems i was experiencing while the car was running but i wont know for sure until i get my new manifold and get her all back together

you took the words out of my mouth there, it's easy to overlook this earth especially if (as with mine) it's broken off the coil carrier. IIRC the coils have their own dedicated earths anyway but Toyota fitted the single wire one for a reason I guess...

where exactly is this ground ground on the coil suppose to be... im pretty sure i dont have on and when i bolt the coil carrier down i never have the rubbers that hold it into place so i just used some washers for now.. is that a big deal?

checked all the grounds.. they are now good but i still have no spark.. im going to check for codes right now

supra.7mgte · 02-18-2010, 06:12 PM

just checked codes.. none at this time anyways.. im at a loss here i have no freaking clue wut it could be.. any other ideas... i timed the cps and even replace it due to the fact that the old wires were very brittle

any one with other ideas on what it could be?

i also just noticed that when the battery is hooked up the check engine light stays light up with the ignition in the off position and key out of ignition. as soon as u turn the key to the run/on position the check engine light will go out. any clues as too why?
