SOURCE: solenoid was bad replaced it

Check the fuel pump cut off switch located behind the carpet on the passenger side up unde the heater box, pull the carpet back and see if the button on top of the switch is pressed down, if not there behind the panel passenger footwell right side same thing also make sure the switch has power coming in and going out. BUT! you gotta be quick the fuel pump relay controls this power and only suppllies power for 2-3 seconds then it turns off. so plan ahead get your test equipment all set-up and surn the ignition on if you have power great turn off the key and move test stuff to tho other wire on the fuel shut off switch get ready and turn on the key power good no power bad fuel pump switch but No power to the switch likely a bad ffuel pump relay.

SOURCE: 1998 chevy pickup won't start. Replaced fuel pump

How many miles are on the engine? Has the timing chain ever been replaced, if it hasn't there is a possibility that the timing chain has jumped a tooth on the cam gear which throws off the ignition timing and will keep it from starting but you will still have spark and fuel.

It appears that you have a venting problem for the fuel tank that is not allowing the fuel to the pump. Run fault codes and check for cannister purge solenoid valve and other faults related to venting

96 Monte carlo z34 won't crank over unless I jump


Sounds like a problem with the key switch, probably the security system. You may only have power to the fuel pump when the engine is cranking.
Is the security light on or flashing ?

Fuel leak


This part is a vent solenoid to the EVAP system. The solenoid is controlled by the PCM & vents fuel vapors to the charcoal canister. If fuel is leaking here you should first make sure your vent in the gas cap is not clogged.This could cause a vacuum in tank & possibly lead to your problem, or the solenoid may have been damaged when the tank was removed & replaced.
