if fuel relay is ok ...could be this relay
Circuit Opening Relay
Circuit opening relay controls fuel pump circuit. The Engine Control Module (ECM) receives an input signal at STA terminal when engine is cranking. Starter signal is also applied to terminal STA of circuit opening relay.
Starter signal energizes circuit opening relay during cranking. Circuit opening relay then provides voltage to fuel pump or fuel pump relay.
Fuel pump switch in airflow meter provides ground for circuit opening relay.
Not guessing as to what the problem is , testing for voltage drop problems with a volt meter . posted a video on youtube yesterday . If your still looking for guesses forget it , no one on here could say for sure without testing the circuit an hooking up a scan tool to see if PCM is energizing the relay . Do yourself a favor an take it to a qualified repair shop . Fuel Pump Electrical Circuits Description and Operation If you can't learn how to test from this guy , better take to a repair shop .
No noise from fuel pump when you turn over the car .First thing get voltage at fuel pump relay checked, is there 12 volt to the relay.If no, then problem is again the relay.---------
To reconfirm the problem, try other test, that is remove the relay and by pass the relay terminals with a jumper wire .Then with 12 volt external battery give power to fuel pump connector and see, if the fuel pump starts, then its clear that fuel pump relay is faulty.----------- Also other problem can be fuel pump inertia switch.If the inertia switch is faulty then also fuel pump will not start.--------
The fuel pump relay on a 1995 Ford Explorer is in the power distribution box, in the engine compartment, driver's side near the firewall.---------- The fuel pump inertia switch is in the right front passenger area it is below the dash but above the carpet in the right hand corner.-------- Its a push button type inertia switch. -------- Fuel Pump Activation When ignition switch is turned to START position, PCM operates fuel pump relay to provide fuel for starting engine. PCM senses engine speed and shuts off fuel pump by opening ground circuit to fuel pump relay when engine stops or engine speed drops to less than 120 RPM. When ignition switch is in ON position, EEC power relay is energized (contacts closed). Power is provided to fuel pump relay and timer in PCM. Fuel pump receives power through fuel pump relay contacts. Inertia Fuel Shutoff (IFS) Switch All models use an electrical interrupt switch in fuel system. During a collision or vehicle rollover, electrical contacts within inertia switch open, shutting off fuel supply to electric fuel pump. Fuel supply is interrupted even when engine is running. A reset button is located on switch assembly. If electrical circuit trips, vehicle will not restart until switch is reset. Fuel system should be inspected before resetting switch. IFS switch is located under instrument panel, near right side of transmission hump.-----------If the fuel pump relay, the inertia switch and fuel pump all checked ok, and fuel pump is working with direct 12 volt source to fuel pump.Then problem relates to computer.The computer (power control module, PCM) is faulty and has to be replaced.---------This will help.Thanks.Helpmech.
You could have a bad fuel pump relay switch. The fuel pump
relay switch gets the fuel pump running in the vehicle during the start
cycle. The terms fuel pump relay and fuel pump relay switch are used
interchangeably. The fuel pump relay begins its job when the automobile
operator turns to the ignition on, but before the motor is actually
running. At that point, the fuel pump relay in some cars sends a signal
to the ignition switch, which in turn sends a signal to the fuel pump
to turn on. Others fuel pump relays have actual circuitry inside of
them that receive the ignition signal and directly signal the fuel pump
to engage.
Hi irvj6ohn: The 1993 and 1994 XJ6 Fuel Pump Relay is located in the trunk of the vehicle on the right hand rear side. It is light blue and black in color. I hope this helps.
