[20016spd]

I have a problem with my 01. First it started showing it was over heating (which it wasn’t), then I left to go pick up a load of calves and the truck started to sputter, and then died and wouldn’t start. Changed the Ecm and I can start it now. But the problem I’m having now is the truck will run real rough and after a few seconds after starting but any load it acts like it’s not getting fuel. The p0118 and p1693 codes are still there. And a few others come up now and then. Any ideas as this truck is my source of income

I suspect a wiring issue.

Have any idea where to begin looking?

If you read through the PO118 article it has trouble shooting steps to follow.

What is your fuel pressure? What other codes come up?

How's ac noise checks out

[20016spd]

 p1693, p0216, p0230, p0118, p0562, p1698, p1287, po217 And one more I can’t remember. At first I’m at 19psi fuel pressure than it drops out

Not sure what you mean by AC noise

Here's a link to the OBD codes and trouble shooting. Quickly looking through they are all voltage related except the 216 which means the timing piston is froze in the pump and cannot reach full advance. Often caused by low fuel pressure, and you have a lift pump code too. AC noise is dirty power being produced by the alternator. It wreaks havoc on the electronics in vehicles and these trucks especially. There's an article on how to test for it in the articles section.
