Right after i fixed my intake manifold oil leak my car wouldnt restart. I sound that if i unplugged the maf it would fire fine and run a little ruff but still run and drive but when u plug the maf back in the car shuts down. Today we tried my maf on my friends ss and it did the same thing so i know that the maf is bad for some reason, but tonight i tried it again and the car will turn over but not start. The car seems to be getting fuel and has spark at the coil but i haven't had a chance to look at the plugs. Any ideas other then opti?

 

Well.. if the MAF behaves the same way on your experimental car and it still doesn't start after putting it back on your car I would say it could be your MAF?
Have you checked to see if all the diodes are in tact on the sensor?

 

I know that the maf is bad, but with a good maf it still wont run

 

looks like its not getting spark to the plugs, could it be anything other then opti?
