supra wont start after tune up

kadinz · 05-12-2010, 03:11 PM

wires cap and rotor, i first replaced the rotar the day before and i got the cap and wires in the mail the next day and replaced them, it started with a problem it would have a random misfire and would barely drive, was good at high rpm's but still wouldn't drive well, got home...fiddled with a few things and it started with still a little misfire but not bad, i drove it around and it got better. i got home and looked under the hood, clamped a coolant line and now its barely starting. i have no idea AT ALL why, checked the fuses and the alternator one is a little dark so i tried to take it out and cracked it, it won;'t come out. i dont know what the hell is wrong. the alternator fuse wouldnt make it do this would it? it fires barely at all..

i'm gonna bump this, i found some oil comin out of the dizzy, im gonna replace the dizzy and the seal..hopefully that will fix the problem? any input will help.

edit: it sounds like its running on like 2 cylinders, spark tested all plugs and it shows only 2 getting real good spark, the rest are not so good.

Check your coil!!! Double check your timing marks and make sure your wires are on in the right order. Most misfires are very simples fixes.

coil is good. spark tested that and its got consistent spark, wires are most definately in order i checked it 132-098 times, timing...doing that today and im checking wiring to see if any wires are bad

but its not just a simple misfire, it sounds like its just running on 2 cylinders or summin.

did you also replace the spark plugs and if you did, did you check the gap?

no, i assumed the guy replaced the spark plugs, well guess what? he didnt..that dumb prick kept the same 6 year old spark plugs in the head when he put the engine in, im pissed but the plugs arents the problem, its running rich i believe...it might be a timing problem.
