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

Can't help you (physical challenges now), but instead of leaving you hanging in the wind, I'll suggest you check over on TitanTalk, as there are numerous threads about this; some having this very title, and a number dealing with our earlier trucks.

That was a lot of help, I've been looking over there but you made me take a closer look and found this thread I'm ready to divorce my 04 Titan w/312,000 miles!
Assuming i did it right, replaced fuel line that feeds the injector rail and inserted a shredder valve to check the fuel pressure, its getting fuel but not building any pressure. this will be the 3rd time i replace the fuel pump.
