After replacement the rocker arms where torqued or adjusted incorrectly causing an engine misfire-backfire through the exhaust. Lost fuel injection at the fuel injector after this.
The rockers where then readjusted and compression tested good. Car starts and run with prime through the tbi throat. Injector gets no pulse(tested with noid light) and the iac also has no activity when tested with the noid light.
Replaced an oil pressure switch. This did not resolve the NO Fuel problem.
The ECM fuse and fuel injector fuse checked OK.
The ignition control module tested Good.
Replaced the fuel filter and removed the fuel pump in the tank as this is what initially I suspected as being faulty.
The fuel pump tested good out of the tank using a 12volt aligator clip to test. This confirmed by a local autoparts house
The oil pressure switch was not tested. Just replaced.
Could the pcm be the problem? Car started and ran before the cylinder head was replaced. It now starts but cannot get fuel to the injector. No pulse as previously indicated?
have the same problem?
