My neighbour had some work done on his truck.........Suspicious?

The question is whether they don't have the time to troubleshoot properly or just don't know how.

That's what I am getting at. Replace the pump add the labour, then diagnose a faulty module??

To boot, I picked up my friends truck for him and asked how much the FPCM was and he said that they "refurbished and cleaned" the old one. Sounds like it was a bad connection to me.

Wouldn't a simple jumper test at the FPCM harness rule out "things that could shut the pump off"?

a test light at the upstreem side of the bullet term...wil give good info of what you have and dont have..a jumper to hot the pump is not necessary most of the time....in all my yrs dealing with gm bullet terminals..dont remember cleaning any...finding a busted wire before the term yes..or a melted term yes...on the oe pumps very comon for them to stop cycling before they die altogether

Exactly......As long as the customer takes it up the tailpipe, there is no motivation to take the time, or to do it properly.

BTW......The fuel pump has been tossed.

In this state we have a law that replaced parts must be given back to the owner. Covers a lot of the "Did they actually replace it?" issues, and even mis-diagnoses. Not much help to the average Joe, I know- most people you could tell them you replaced a pump and hand them a bag of spark plugs and they wouldn't question it, but...

Reminds me of years ago when I took the wife's Saturn into the dealership to take care of a dimming issue with the headlights- probably bad/dirty grounds. I was strapped for time and figured the techs would already know where all the grounds are, and could take care of it fairly quickly.
Next day they call me and say to come pick it up; they could find no issues. When I got there I asked if they had checked the grounds as I suggested; they told me (with a straight face and in all sincerity) that Saturns have plastic bodies and therefore no grounds. I couldn't get out of there fast enough.
When all was said and done, I fixed it in about 20 minutes- it was corroded grounds.
