i have a 06 dodge 2500 spins nice and fast but will not run it has been hard to start for a few days now it will not start i took the line off relief pressure valve and its not leaking it seems to be getting fuel any ideas

 

If you have way to monitor rail pressure while cranking. Could have excessive injector return flow. Start capping injector line at the rail until you find the one causing the no start.

 

okay what should the rail pressure be

 

4k or better is what you need to see on the gauge

 

TIPM gone

 

Pull the alarm fuse.

 

ok thanks everyone i replace number 3 injector
