I am getting a no start condition - stopped suddenly. Had a few times where it was hesitating and had once where it was surging in reverse. It feels like it wants to start one in a while. I can hear fuel pump energizing . Very little fuel at the rail. Filter is new within about 6 months.

OK that was info from my Father in Law - its his truck and I have been kind of helping him lately with stuff. I don't think he has touched the pump. I just know that he doesn't take great care of things as evidenced by what I have seen. I took a look at the module and it looks very corroded - it broke down like 6 months ago and he has just now enlisted me to help him get it going. So if it was wet, it has dried out since. I can hear the fuel pump energize, and the only code I could pull was po446 for evap canister.

Ok so bear with me here it is 3 degrees out and I am trying to get this truck started. Replaced the fuel pump drive module. Same condition. Crank no start. Once in a while it kicks like it wants to start but just goes back to spinning. Fuse 27 is ok. Not sure how to check the relay. I can hear fuel pump energizing. As far as I know fuel pump has never been changed. Only thing I can see is that one of his workers must have been messing with it (he is a plumber ) and there are two of the coil boots that the small bolts holding them in are missing. Any ideas? The motor sounds a bit different while it’s spinning - but it does kick once in a while.

Trade the fuel pump relay with a relay just like it from something else and see if this changes.
