Re: 2000 C2500 stuck in closed loop.
Went to drive it today and it won't start unless I put the pedal to the floor. Then when it starts it barely has enough power to move. I plugged in the scanner to see what codes there were and it's not even powering the scanner on.

Re: 2000 C2500 stuck in closed loop.
Auto Zone or Advanced Auto has loaner tools. Get a fuel pressure tester and check the fuel pressure. Post the results.

Re: 2000 C2500 stuck in closed loop.
Fuel pressure is at 62 psi when the engine is running. Changed the fuse and still only getting P0174. Pickup has no power to move itself and shakes very bad.

Re: 2000 C2500 stuck in closed loop.
I got it home going about 5mph. Couldn't go any faster. Luckily I was only a mile from home.

Re: 2000 C2500 stuck in closed loop.
This now sounds like flooding. Perhaps a leaking injector, regulator, or fuel line in the plenum. Does the fuel pressure drop off quickly once the pump is shut off?

Re: 2000 C2500 stuck in closed loop.
I will check that tonight. I thought it sounded like the timing was off. The hold down on the distributor was tight but the paint mark was way off. Not sure what happened there.

Re: 2000 C2500 stuck in closed loop.
I also took the cap & rotor off and they are toast. They are probably 5 years old. Isn't that a little soon to be shot?

Re: 2000 C2500 stuck in closed loop.
Turning the key on is 65 psi. Turn the key off and the fuel pressure drops to 0 psi in 5 seconds.

Re: 2000 C2500 stuck in closed loop.
That could be a regulator, fuel line, or the pump leaking back. Based upon the reported symptoms it sounds like the pump may not be the prime culprit.

Re: 2000 C2500 stuck in closed loop.
No fuel lines are leaking. The spider assembly and fuel pump are new. What's the best way to find out what's leaking?

Re: 2000 C2500 stuck in closed loop.
With the return line pinched off the pressure still drops right to zero. Would that mean the check valve in the pimp is bad? Thanks.

Re: 2000 C2500 stuck in closed loop.
It was spraying out of the regulator.
