Where is the fuel pump relay on a 2002 Mustang?
There is a fuel pump relay. The Integrated Control Relay Module is located on the right hand side of the engine comparment.
Is my 2002 Mustang GT fuel pump driver module bad?
My Mustang 2002 GT just stopped running, like it ran out of gas. Which I thought it did, because I was very low on gas, but the Low Fuel Light did not turn on. I put gas in it, but it has not started since the failure. My scanner reported a 1234 code, which is a Fuel Pump Driver Module (FPDM) offline code.
How to power up a fuel pump in a Mustang?
Try powering the fuel pump up manually first, Hot to pin 10 on the FPDM (BN/PK) and ground to pin 3 RD/BK. If pump runs ok and builds pressure then load test the 2 wires from FPDM to PCM.
Is the FPDM driver module bad on a Mustang?
FPDM have been in use on Mustangs since 1999 and there all the same for V6’s & V8’s and although I sell alot of them (mostly to shops like Zone 5 or VMP) I can honestly say, since they’ve been in service, I’ve never sold one due to a circuit failure…..that doesn’t mean thay can’t/won’t fail but I haven’t seen any issues out of them….yet

How can I tell if my fuel pump relay is faulty?
2. Engine does not start. Another symptom of a faulty fuel pump relay is an engine that does not start. If the fuel pump relay fails the fuel pump will be left without power. The engine may still crank when the key is turned, however it will not be able to start due to lack of fuel.
How does the fuel regulator work on a Mustang?
The pressure in the fuel rail and intake manifold should be maintained at a level to suit the optimum air/fuel ratio. Your Mustang, as well as most fuel injected cars, has a one-to-one ratio fuel regulator. It varies the fuel pressure by being connected to manifold pressure via a vacuum connection.
