Wires and plugs were AC Delco from dealer. The old plugs were in good color and uniform.
Crank sensor was clean.
I decided to check the fuel pressure again and used a friends gauge.
52psi key on 44psi running. Guess I know what I'm doing this weekend!
That pump doesn't even have 12,000 miles on it.Going to get the next one from the dealer.

the pump to get would be the dephi pump...these are available at non gm dealer stores you will save some money....
airtex is well known for pump failures after a few months...
replace the fuel filter if you believe the pump has disintergrated this may have fouled the filter,,,and to be safe replace the fuel relay as this bad pump could have damaged the fuel pump relay contacts..
after you replace the pump always get the pressure guage out and check pressures .....give us some feedback on how you made out good luck................
