GMC Repair: fuel pump-GMC, gm goodwrench, ac delco

Question
Morning Jim,
This is a 97 GMC 1500 2WD 350. Has 195000 miles.
Truck has gotten hard to start (turns a long time). I can hear the fuel pump after it sits several hours. I have had to scoot some starting into the air intake a few times then it catches & runs. I thought elec. fuel pumps either worked or not. Can it slowly go bad? I did tune the ignition too, cap rotor & plugs. I changed the pump some 30-40 miles ago and expect it wasn't AC Delco. Won't make the same mistake again if you think that's what it is.
Thanks much
Jerry

Answer
It is possible that it is a fuel pump. The GM pumps can start to bind and will slowly go out. Also they can cut out while driving causing an engine stall. I would advise you to check your fuel pressure, it needs to be between 60-66psi. to run rhe truck. Also I would advise bringing it to your local dealer if it is a fuel pump simply because GM Goodwrench provides a lifetime parts and labor warranty on dealer installed pumps.
