Broken down. Fuel pump issue?

We have a 96 fleetwood southwind with a big block fuel injected Chevy engine. We are stuck in a Walmart parking lot. The engine started sputtering and stalled out. I was able to get it restarted and get to an auto parts store and put a new fuel filter on. It started right back up, went another ten miles and it died again. The pump in the tank is coming on when the key is turned to acc. I'm getting fuel up to the top of the engine before the injection system. I'm getting spark from the coil, but it still won't start. I was just able to get a fuel pressure gauge and will check it in the morning, but I'm looking to find out what the spec is for fuel pressure on these injected models is. I figure the pump must be wearing out and when it gets hot it quits, but I would like to know what pressure it should have before I go through the trouble of dropping the tank. Any help would be appreciated. It's not going to be a fun trying to get it done in a parking lot.

    I believe the Fuel Pressure should be 9-14lbs on a TBI motor.You would need to monitor the pressure while driving to see if its dropping when it stalls.
  • Check your fuel filter again, you may have a bad load of fuel. Did you mistakenly fill it with E-85?? Your fuel system is not designed for it and will be destroyed if you use it.
  • What codes are showing? May not have been enough to set the CEL but there might be codes.
  • You did not spec your engine but must have 50 lbs pressure to start is all my book states with fuel injected Chevy engine.
  • Here is a lot of info on testing the fuel pump. Sorry I don't know the specifics of your pump.
