Our point is, if you have good pressure, the filter and pump are ok. Easy (if you have the right tools/equipment) to rule out the filter/pump.

The odd codes REALLY bug me, reminds me of the Ford I was talking about where a sensor went bad and I ignored the light..... a few months later, the MAF failed and the PCM didn't have enough information to run the engine.

Again, HOW OLD IS THAT BATTERY?
