Need some help here, truck died while driving
Truck: 1993 Chevy S10 Blazer 4wd CPI Vortec.
This morning driving along at constant 55 mph, truck just dies. Pull over to side of the rode and after about 3 minutes, fires up and drives for about 1/4 mile and then dies. Will not fire after this. Wife picks me and takes me to get Iroc and I go to work. Go back at 2:00 pm, fire truck up and runs for ~1.5 seconds and dies. OK, I think it's the fuel pump. Have the truck towed home, put fuel pressure gauge on and get a constant reading of 58psi (spec is 54-62) so that is dead on with no bleed down.
More background: On 12/24/05 the truck started running really erratic, stalled and tripped a DTC. Got it started and drove home with it still running very erratic. (thought it was the fuel pump then, too). Checked fuel pressure then and had proper fuel pressure. I hooked up my laptop and started scanning (using EASE diagnostic system). DTC was 32 EGR. Ok, I thought, just go get an EGR and replace it. Well before I did, I reset the code with EASE software. Low and behold, everything cleared up and the truck has been running perfectly until today's events.
OK, here's where the help comes in (sorry I'm longwinded), could the truck not running/starting up have anything to do with the EGR maybe be stuck open? I scanned it after checking the fuel pressure and did not receive any DTCs, which I would hope would eliminate the EGR along with any of the other Emissions Control sensors. Could it be the ignition control module? Any educated guesses (I know that's an oxy-moron).
Truck has fairly new plugs, wires, cap and rotor (all done spring '05).
Any help/suggestions would be appreciated.
Yes, I've done and will continue searching on the subject
