Location fuel pump relay on a 1999 mitsubishi eclipse spyder cn

no engine told 2.4 or 3.0L?
the SM covers all that , the service manual..
2002
Mitsubishi Eclipse Spyder ! both pump and relay? same page in the book
buy one or rent it online, I DO all mine. paid.
best is test fuel pressure cranking dead engine or running,
PSI spec, factory tested. using real gauge (hand)
bad fuel filter , bad FPR< or bad pump, or not at all, barking up wrong tree most do. EFI logic confuses many.

relay switch is in the engine bay fuse box cannot remember of hand its location but there is only 2 or 3 relays in there.

The MPI relay is usually in the center console, behind the radio.

The two relays for the front [main] wipers are part of the front ECU [engine computer] and are not serviceable separately. The front wipers are powered by a 10 amp [#22 in the relay box] battery hot fuse and a 20 amp [#18 in the junction box] & two 7.5 amp [#20 & #23 in the junction box] ignition hot fuses. The front ECU is located under the hood. It sits on top of the driver's inner fender well.

pull back seat and remove 4 screws on plate and pull cover unscrew cap and remove wires and hoses

I dont't know specifically per vehicle but most are position on the body/frame within a foot of the tank itself. Look up and image on line and then pop under your car and take a look.

the fuel pump relay is under the hood on the drives side if u look in the oners manual it will show u the excact location hope it helps
