Alright, got this 1988 K1500 5.7 from my father. It was sitting in a field in Idaho for a couple years. I put a new battery in it, and got it started. It would only stay running if I pumped the gas. I dropped it into drive and kept pumping, about 30 seconds later it throttled up and ran and drove perfect, idled perfect and I drove it 700 miles to colorado. I turned it off multiple times to get fuel, started and idled perfect and ran perfect every time.
I was almost home, a few exit ramps from mine it started bogging down. I pulled onto the next exit and it died. I did a roadside tune up (cap and rotor and plugs). I towed it home and have since been throwing parts at it. I've done both coolant temp sensors, both the oil pressure switch and sensor, a couple questionable vaccum lines, fuel filter, map sensor and replaced a frayed coolant temp sensor wire. Still doing the same thing, starts and only stays running while pumping the gas just like when it first started in Idaho.
I does show low oil pressure (hence the thought to replace the oil pressure sender and sensor), and it does backfire occasionally while pumping the gas. Figured I would post on here and see if anyone has any ideas on where to move on getting this thing running.
