So I did my yearly cleaning of the intake system including the intercooler and intake manifold and now my car wont start. All I did is wash out and clean the piping, intercooler, and intake manifold by taking it off the car, cleaning it, drying it, and install it back.

I have checked that I do get spark but it seems as though the injectors are just not firing. I checked the voltage at the plug with the key to the on position and it was a low voltage like 3.v I also checked voltage at the ecu to make sure there was even power going to the ecu and that all checked out right.

Im thinking it is a ground issue but I think ive checked everything I know of. Does anyone have any input as to what it could be?

did you forget a ground somewhere when re-installing the manifold?

I was thinking the same thing, the only grounds I have are the two that go on the 4th intake runner and the large one that bolts to the plenum near the throttle body.
