Here are some things to check for your symptoms. It sounds to me like the check vavle in the fuel tank, but here are some things to check:
-Binding or sticking TPS, or high TPS voltage with throttle closed.
-High resistance in coolant sensor circuit (see Trouble Code 15).
-Incorrect fuel pressure or contaminated fuel.
-Improper EGR operation, leaking, binding or sticking EGR valve.
-Ignition system malfunction, worn damaged or fouled spark plugs.
-Defective in-tank fuel pump check valve allowing fuel to drain back to tank after engine is stopped.
-On V6-173 (2.8L) if engine starts, then dies, open distributor bypass line. If engine starts and runs properly, replace pickup coil.
