I blew a head gasket a week ago and just finished putting everything back together and am working out some problems.

I had the car starting and running ok for a little wile and, I was working on misc things.

And now when turn the key to the second on position the 4th injector stays on always. I must have lost a 1/4 tank in that cylinder It was coming out of the exhaust manifold when I pulled the plugs I must of shot a 3 footer out of the cylinder.

I stuck a noid light in the plug and it is on when the key is on, the others are off.

Does the ecu pulse/ground the injector ? Or send power ?

Should I check for a short to ground, between ecu and injector ? If so I need wiring schematics.

Anyone have any imput ? or anything i should check ?

I am starting to stressssss

Thanks,
Jack

 

yes, it pulse grounds the injectors. injectors are Aplug in the ECU

check for injector wires in your engine bay that could be possibly grounding out.
