My truck has constant fuel with the key on but no spark. I have changed crank sensor, cam sensor, cap and rotor, coil. Checked all grounds and fuses, still nothing. Has no power to the coil. Please help. Thanks in advance.

It sounds like the ASD relay has gone bad. Here is a guide that will help us confirm the problem.

Yep it sounds like the PCM is gone and needs to be replaced.

Here is its location, I would get a used one so its plug and play.

Please let us know what happens.

Cheers, Ken
