Problem: my truck has been lacking power and seems like it's mis-firing more now. It just started backfiring under a load. Not all the time, just when I take off from a stop and the RPMs drop to 500 (manual). I've heard it could be the fuel pump, but I'm not sure. Plugs were replaced with champion truck plugs, problem still persisted. Changed the plug wires to mopar performance ones, still there. If it is the fuel pump, where is a cheap place to buy it? So far, the only place I've seen is the stealership.
Oh, one more thing to add. When the RPMs are up around 3-4, it doesn't do it (at least that I can tell). Under 2k and especially under 1500, it does it big-time. Starts bucking like wild. Haven't ran a fuel pressure check on it yet, but I'm pretty sure the fuel filter/pump is the original one (165k).

Yeah, no distributor on this pig. Just 2 coil packs on the pass. side valve cover. At first I thought it was an ignition problem. But after gapping the plugs correctly and changing plug wires, I have reason to believe it's a fuel problem. Just wanting to make sure, and get some other opinions.
If it is the original fuel pump you are overdue to changeit. I think they are to be changed every60-100kbecause the fuel filter is attached to the pump. Mine showed up going up a hill under load and the engine started bucking.
Great site. This is my first visit. I have a 98 V10 with 75k miles. It's my commuter truck. Today I noticed a loss in power going up a hill then an odd idle at park. Basically everything is bone stock and original. Sounds like it might be fuel related. I'll check pressure tonight. Any other suggestions?
Checked the pressure tonight - 50psi. The book says 35-45 psi and if higher, the regulator/filter unit might be the problem.
^^^^^^^^^ i was just about to suggest that, wow all these v10's pop in just as i leave, figures, but one thing also to check is the #5 and #7 wires are separated, i know the harness that goes acrossed the front of the engine practially puts all of them together but make sure you have them spaced away from each other they have a tendency to communicate and you don't want that, that will give you a wandering idle, mine did that. one other thing, contact email@example.com and tell him you have a v10 and you want a tuner, not sure what he's charging but should be around $275, even though yours are stock, you will not believe the difference in power, not to mention you improve your gas mileage trust me i know, i used my v10 to haul travel trailers all over, once you get over the difference the tuner makes, i suggest you use the 87 tune with 89 octane or 93 don't use the 89 tune or 93 tune unless you just like spilling your drinks or snappin your neck, but i was getting 14.8mpg with a 4000lb trailer 87 tune, 89 octane, and if you haven't done soo yet, change your thermostat to a 180, my truck had dual exhaust, 2 cats, 1 muffler that had the "X" in it, magnaflow cats hi flow, dynamax muffler, she was quiet with a little rumble, but once you smashed the gas pedal and got it around 2500 rpm's sounded like a honda civic, funny how people are looking for a honda and instead see a big a$$ truck screamin down the road.
