I have a 95 Dodge Dakota 2.5 4 cylinder. Recently I thought the fuel pump was out in my truck so I changed it. I was wrong. The wire harness under the hood was grounding out causing the auto shut down 30 amp fuse under the hood to blow. So originally the old pump was not bad. All I did was remove the harness under the hood and cleaned up all burnt wires and replaced harness. That stopped the fuse from blowing. Before I figured that problem out I just assumed it was the fuel pump. Bad mistake, it cost me $165.00 and 5 hours of my day and a fuel gauge. Any suggestions or ideas would be greatly appreciated. Ive already posted this question once but I failed to explain it properly. Sorry for repost.

did you replaced just the float , because if the resistor that messures the level is not good you didn't do any thing you have to change the level sensor next to the pump..,Im sure that;s all the problem, you should also check the wiring next to the pumpand any connector down there
Here's the procedure for checking the fuel pump. I would 1st change the fuel filter, 2nd would be to scan for engine codes (free service at most parts stores), then check pressure (on a cool day, below 70 degrees) Good luck, let me know what u find. Curt

The Fuel System Pressure
44-54 PSI (Pounds per Square Inch)
Vent the fuel tank vapors by loosening the fuel cap
and unplug the injector wiring harness from the main
engine wiring harness. The next step is to
attach an electrical jumper between a solid
ground and the fuel injector terminal pin number 1.
Next, connect an electrical jumper between the battery
positive post and injector terminal pin number 2
for a period of time not to exceed 4 seconds. This
serves to bleed down pressure from the fuel system.
Install a fuel pressure gauge on the fuel rail service
test port and energize the fuel pump. This will bring
the system to a stabilized fuel pressure that can be
visually verified on the gauge.
dont take carb off, drain fuel from tank if you got bad gas, fill with good gas, pull fuel line off carb and turn on key if have electric fuel pump, this will clean out line. get a spray can of carb cleaner from auto store and spray carb. hook up fuel line and try to start, should clean out carb with fresh fuel
I had a similar problem only I was lucky enough that my gas gauge started working after it got lower than a 1/2 tank. It ended up being the float inside the tank. I ended up paying around $90 for the fuel float and it started reading the gas level correctly. But after 2 weeks and some severe cold weather, my engine wouldn't recieve any gas, ended up being the fuel pump. In buying the new fuel pump, along came a new float attached. So if your planning on replacing the float, go ahead and replace the whole pump, it will save you time, money, and hassle after its all over with.
