Welcome to FTE, Chris!

Another question: Does the Wait To Start light (WTS) come on when you turn the key to Run, before cranking?

2. Stutter and miss until dead

Sounds like you need to check the harnesses under the valve covers.

And

Was that a FOMOCO CPS you swapped

Well I'm pretty sure it's not still at the intersection. Tell us the rest of the story. It is important sometimes.

Have them ohm the harneses out under the valve covers before springing for an IDM. If the WTS light is comming on and going off at KEY ON the PCM is passing self test.

Okay, this is awkward what happened to my truck today. I cleaned the inside of my truck out, cleaned the floor windows the works. I go to start my truck to leave and notice fuel pressure 0PSI with the key forward, so a red flag went up. I look for a WTS light, nothing. So i thought to myself, oh the fuse for the fuel bowl blew and i need to unplug the bowl. After checking every single fuse, and all tested good, i go to try it again. Still nothing cranked forever but nothing, so i go ahead and pulled the fuel heater plug anyways, and then there was fuel pressure and the WTS light, and she fired right up. Anyone got ideas on this one? If it was shorting out shouldnt it have blown the fuse?

What kind of code reader did they use? This is very important before getting a new PCM which would be very rare. The majority of scanners/readers will not read our codes unless properly equipped.

Wow, and no, unless it was somehow overloading the lower PCM voltage through a short that wouldn't blow a fuse but upset the PCM. I'm all ears on this one.

not exactly sure,but i will find out first thing tomorrow.I was thinking it was kind of odd to need a new "computer" as they call it and wanted to try to do some research before a new one is bought.There is one good thing to it,that we just bought the truck last week and we talked to the first owner before us and he said he had no problems but will pay for whatever is wrong with it because he didn't know of any problems
