98-Mitsubhi Eclipse - 2.4 SOHC. Stopped running, checked voltage at fuel pump, only 10.8 to 11 volts. Ran jumper from battery to pump it runs. Cam and Crank sensors check OK. Switched pump and MFI relays no change. Where is the pump relay module located, could this be a culprit. Any help or suggestions are greatly appreciated.

storm what engine? 4xe1 or 4xf1 SOHC or DOHC (twin cam)?
its really an Isuzu Impulse in snack skins (badges)
does test fuel run engine? that is step 2.
if the cam timing belt slips, the DOHC goes boom.
the SOHC engine belt slip,cause no starts, due to huge
compression drop, and fails the test fuel tests.
SOHC, keyon, 30-46PSI
same for both. engines
but as all mPI engines it drop running at idle.
and rises at WOT> (FPR actions most work right running) ask
but its no running
ever do a 60,000 interval tuneup with a new cam belt.
You might want to double check that connector to the fuel pump. These cars are known for melting the inside of the connector and causing a poor connection. You'll need to remove the pump also to check the inside of the pump connector. Look for a dark brown discoloration. If you do have this discoloration, replace the pump module and the electrical connector. You may want to test the voltage to the connector to make sure that you have 12 volts going to the pump
You should not see any voltage after the 2-second prime until you actually start cranking the engine. If you don't see power on the grey wire when cranking, try jumpering across the fuel pump relay terminals
alternator. Check voltage at battery with engine running and jumper cables removed. Voltage should be at least 14 volts. if not, replace alternator. If you don't have a voltmeter, remove the alternator and have the parts store test it for you. Let me know if you need instructions or have more questions.
should have 12 volts at pump during engine cranking. with key in "on" position, the fuel pump only gets voltage for 2 seconds if engine is not running. Read voltage during cranking. Check fuel pump relay in battery jucntion box under hood.
Personally I wouldnt bother tracing the wire as it is probably not worth your time, and just run a constant 12v from the battery to the relay on like 10ga wire. There is probably a short somewhere in the system which can be a real headache to find.
Also it may sound dumb, but check your fuses, and the fusible links under the hood. Chances are that they are all fine though, especially if you have dash lights.
