Truck Quit

[DareDog]

2005 5.3l 1500 130k on it. The other day going off an off ramp the truck quit and would not re fire. turned over but would not fire. checked fuel pressure at motor and it had it. it has enough fuel pressure. changed the crank sensor and that was not the issue. its throwing no codes. so what could it be? something electrical?

no start no codes, check ecm fuse and wiring harness

Now it will start up fine and once it gets warm it shuts off.

Those are the worst to hunt down. A Tech2 is your friend.

Check fuel pressure with a gauge sounds like the extra fuel provided when cold is making up for the lower fuel pressure.

Ground wire was the issue. Not 1 but 2 problems on 1 wire. One on the front and other was on back of the motor.
