i just replaced my opti and it fired up and ran for a few minuites, but right when i pulled out of the driveway it stalled. now im getting no spark. at the plugs. i put my friends new coil on and got nothing.
if i pull the coil wire off the opti and ground it should i get spark? or do i have to pull the coil wire off the coil side and ground it? if anyone has any ideas of what it could be it would be a great help.

 

The first thing I would do is check fuses, especially the IGN fuse.

 

And that would be the reason I sent back a perfectly good opti about a year ago. It was the fuse under the hood in the fuse block on the drivers side. Sometimes you need to look a little further before you assume it's the hard things...........all that work for a fuse.

 

After an engine swap I had the engine warming up and it died and did not start for 2 friggin days after. That is when I discovered one of the female pins in the opti end of the harness on top that runs to the passenger side of the intake was pushed up inside the plug a little too far. Definetely a feak thing but free to check.

 

i checked the fuses and they were still good. i pulled the wiring harness plug from the opti and it looks like the prong on the red wire with the back stripe is pushed back a little farther than the rest. shouldnt i get spark at the coil even if theres no signal from the computer at the opti? i thought the spark starts at the coil then goes to the opti

 

The pcm needs to see the opti spining in order for it to send the signal to the coil. I think you found your problem. I think I stuck a thin piece of wire in from the wire side in order to push the pin back out.

 

does anyone know were i can get that wireing harness? i pushed that pin out that was pushed in and i still have no spark. the pins look a little corroded so i think it still might be that plug. is there any tests i can run to make sure thats what it is

 

I would try to borrow one and test it out on the car. I priced one at one point and don't remeber what the price was but it was enough that I fixed the one I had instead of buying the new one.

 

make sure that is the problem, but you can buy one here, dealer wants something like $75 for one

 

thanks, im gonna try mine on my friends car tomarow and see if thats the problem.

 

ok, we put the opti harness on my friends car and it fired rjight up, so thats not the problem. i think it might be the distributer its a remaned autozone. but it ran fine for like 5 minuites then it just died. does anyone else have any ideas of what it could be before i pull the opti again
