Subject: RE:Intermittent Problem by CFI-EFI on 2007/12/31 15:49:13 Keep doing what you have started. You are using the exact correct method of testing. Unfortunately, you will have to wait for the problem to reoccur to know if it is a fuel pressure problem or not. It could be the sock as Case suggested or possibly something floating around inside of the tank, intermittently getting sucked to the sock, blocking the fuel getting to the pump. Your symptoms don't sound like any fuel pump failures I have experienced. The pumps I have seen go, either slowly weaken, where their output and pressure gradually reduces, or they just flat die instantly with no prior warning. I have never known a fuel pump alternate between working just fine, start to run weakly and then recover. My experience is that once they start to go bad, they continue getting worse until they totally fail. If it isn't fuel, again, I agree with Case on the ignition module. But as much trouble as you are having with the fuel pressure testing, the module will be worse. I wouldn't jump around trying a bunch of different things. Be patient and keep to a diagnostic plan. If you are getting restless waiting for another incident in order to check the fuel pressure, you could pull the pump and check the sock, the tank for debris, loose wires or any other anomalies. RACE ON!!! |
