Underhood fuse block swap out relay #7 thats the ECM relay.
Ground Circuits Using a DVOM, touch negative voltmeter lead to a good ground. Touch positive voltmeter lead to each ground terminal. With vehicle running, voltmeter should indicate less than one volt. If reading is greater than one volt, check for open, corrosion and loose connection on ground lead. See ECM GROUND LOCATION table for ECM ground location.

SOURCE: have a dodge 1993 b250s replaced fuel pump, now no power

if you have no power when driving or acceleratiing it could be the fuel filter if not replaced could be clogged up. if your getting good fuel pressure to the engine could need a tuneup. if your not getting power to the pump and it plugged in check the ground wire going to the frame from the pump could have a bad contact.

SOURCE: no power to fuel pump 1996 isuzu rodeo

well i got a salvaged ecm from a junkyard and put it in, still did'nt start. took alternator off to have it checked , it is fine. put it back in and now it starts and runs fine. check the alternator and the connections, i heard the alternator controls power after the initial ecm prime when it is turned on. i have no idea how true it is, but worth a shot. if you can find a cheap ecm for a junkyard (mine was 75 bucks) i would try that afterwords.

Have you checked for an exhaust restriction? Most garages and exhaust shops can perform a back pressure test for a minimal fee.

1993 izuzu rodeo code 54


AutoZone will usually diagnose codes for free in hopes of selling you the parts. Sounds like a fuel filter but could be a weak fuel pump. It is most likely an electric pump located inside the fuel tank.

Replacing feul pump holden rodeo 1993


Cutting a hole in metal above fuel pump is way easier than dropping the fuel tank. Avoid sparks though! A shortened oiled hack saw blade on a jig saw may do the trick. Cut three sides and bend panel back, seal back with bondo, liquid nails, puttty two part epoxy, etc.

SENDING UNIT ???????


most of fuel pumps were in tank, wire corrodes is harness under right front seat floor pan to tank
if fuel pump buzz is heard and car runs and when it doesnt run you cant hear the fuel pump try
turn ignition off wait 10 seconds
turn ignition to on position to (prime or hear pump buzz)
no buzz fuel pump not working check fuel pump relay(swap with another) and try again?
you could use test light to pump wiring and make sure your getting power to pump on this prime test no power relay or wiring problem.
power at pump, but no buzz fuel pump faulty
