90 5.8 EFI
new Jasper motor 2,000 miles ago
was running great now has no power and spits and sputters
Fuel pressure is in range running at idle and w engine off
plugs look good

pulled the codes as follows

KOEO

34
41
95

KOER

12
22
44
34

I feel the 95 code may be the cause of the others (fuel pumpsecondary circuit fault)

Haynes says check PCM to GRD

PCM would be the fuel pump? So I need to check the wiring on the ground side coming from the top of the fuel tank?

Took a quick look in the dim evening light and could not readily find a ground wire under the truck.

Does anyone know where this grounds to? And am I on the right track?

TIA

Mike

PCM would be the computer, and it's ground near it if I'm not mistaken.
