My 2004 truck suffering from the crank, but no start symptoms. Finally had some time to look into and take some voltage measurements at the IPDM. The crank sensor in the transmission housing was replaced and as about 3k miles on it. The camshaft sensor, according to the dealer the 04 only as 1, was replaced and as about 1K miles on it.
Starter relay checkout - ignition switch getting 9v, starter motor getting 12v and TCM inhibit switch getting 12v.
Fuel pump relay checkout - fuel pump 12v, ECM voltage at the relay was inconsistent because of the difficulty getting the meter probe. Disconnected fuel line at engine bay, it primed when key turned on and delivered fuel when key turned over.
MAF sensor - ignition on 12v, ignition crank 12v,
Installed a new ECM relay - ignition coils 12v. There 3 ECM voltage location: pin 30 ignition on 12v, ignition crank 12v, pin 4 ignition on 12v, ignition crank 12v, pin 7 ignition off 12v on position 12v, crank 0v
Would appreciate if someone can check the voltage on their vehicle for pin 7 in the ECM relay. Below are pics of where its located.
Thanks in advance
