Question about 1998 Dodge Ram 1500 4WD

1 Answer

Fuel pump will run when jumpered.

My 98 Ram 1500 5.2 L died on me yesterday. No warning. Will not start. I have swapped relays and fuel pump will not run but it DOES run if I bridge it between the relay and ground on the vehicle but engine will still not start. Is this a sign of a bad PCM?

None of my analog gauges (fuel, volts) are sweeping when I turn the key.
Also, I am not sure if this has anything to do with it but my interior lights were "pulsing" at idle the day before.

I replaced the fuel pump on my 2004 1500 5.7 liter. Started at first but only ran at idle for a few seconds and died. Now i have no fuel pressure at all. Also the wiring connection at top of fuel pump


gotta start with the color code of the wiring. verify that is correct first. you have to have fuel pressure for it to run obviously so make sure you wired it correctly. Here is the color code according to Mitchell OnDemand
black/orange= ground for fuel pump
orange/red=power on for fuel pump(only gets triggered from fuel pump relay)
dark blue/white= signal to pcm for fuel level
dark blue/ dark green= ref voltage

If that is ok then check for relay activation. Fuse 17 is the power source for that relay. If you have a good fuse but no relay activation you could throw a relay at it but if that doesnt do it then its gotta go to a shop. But if you are curious....
Relay code
pin 30= hot at all times
pin 86= relay control trigger from the pcm
pin 85= hot in run or start
pin 87= power source to fuel pump.(i.e. orange/red wire)

the relay will have numbers on it designating the correct pins. Get that right first then move on to the next. I'll be here. Good luck!

Dodge 98 ram 1500, . got new battery, changed the fuel pump, relay okay, fuse okay.. new idle/air valve new plugs, wires, coil, distributor, cap, got gas in it.. will start, but a few minutes later will...


I would take a look at the plugs and see if they are fouled. You might have a bad fuel pressure regulator. Also, the control module or pick up coil could be bad.

98 GMC k 1500 pickup. I can hear my fuel pump whine when I turn my key on , start my truck but it dies after a second or so. Just replaced my fuel filter still the same.Any clue why it won't stay running


have you tried the fuel pump relay, the relay coil may be overheating and dropping out. Or there is **** in the pump filter at the tank end if it has one on the lift pump end itself (i.e. in-tank filter)

Fuel pressure intermittently drops causing sputter and die.


check for 12v constant at your fuel pump if you are not getting that replace your relay.
if you are getting 12 volts at your fuel pump the fuel pump is possible to run tuel it gets warm then shut down to a lower rpm I would then replace the fuel pump
