All,
I have a 2000 5.2 1500 ram, 4x4, 5 speed, stock. A week or so ago I got gas at a station that I typically don't go to. A few miles after getting the gas the truck performance took a dive. I was not able to get the truck to idle and it would just want to shut off. I was able to get it home thru some fancy footwork with the clutch. I dont have a receipt from the gas station so I really dont have any proof that I got gas from them (big mistake). Since then I have removed the bed and drained the tank dry, cleaned the filter screen at the base of the fuel pump module and put in fresh gas along with some dry gas chemical. Prior to draining I did siphon out water from the tank.
Currently the truck will start fine and run good for about 2 minutes after that the idle will vary between 1000 and 600 rpm till it stalls out. I have already ruled out possible catalytic problems by removing the catalytic and having the same results. I have also ruled out the plenum by not smelling gas thru the oil dipstick. I was able to swap the map sensor with one from a buddies truck (2001 same style) and there was no change. I removed the IAC and cleaned it and there was also no change. I have not touched the TPS as of yet. I have also tested the battery and alternator and they are fine. I suspect that the pump may be on its way out but I am not able to measure the fuel pressure due to not having a guage. If I was to push the schrader valve on the fuel rail while the truck is at idle should fuel "shoot" out or "drip" out - would this be a good indication that the pump is shot?
The truck did run fine prior to getting the new (bad) gas.
Any suggestions are appreciated.
thx.
