1995 dodge ram van 5.9 b2500-fuel pressure light comes on every now and again. could it be my oil pump? where is it located and how hard to replace? or maybe a sensor? where is that located?

Question edited for clarity.
Question moved to model category.

The 1994 does according the video, so it is likely your does as well.

Its located behind the distrubutor its pretty easy to get a

the dodge web site shows it. there,
as does the shop manual shows it.

The only way to know if you need engine repair or you have a bad sender is to hook up an oil pressure test gage to the sender port and manually check the pressure. You will need the deep oil pressure sending unit removal tool to get the sender out (I did this).

If the pump continued to run after shutting off the car you fuel pump relay was probably staying latched. I would replace the relay as well based on your info. Along with the pump the fuel filter should be replaced too and fuel pressure should be checked. Make sure your ground is good also.

You need to look at your fuel pump it does not pump to specification when it gets hot. You might just have to replace it.

Good luck

i would say they sold you the wrong fuel pump

The Sending Unit is Inside the Fuel Tank at the End of the Intake Line. You will have to Drop the Tank and Change it. Your Guage should be just fine after the Repair

sounds like a possible pluged fuel filter or a tired fuel pump. the pump is cooled by the gas. so if you work it at 1/4 tank or below it tends to get hot. but towing may make it hot anyway. check fuel pressure and the replace the fuel filter

sounds to me like the fuel pump is bad, when it warms up it dies, try to check this by filling the tank and running a while, then run the van with a near empty tank and see how it does. A full tank of gas should keep the fuel pump cool as it is surrounded by the liquid. I had a similar problem. when my tank got to about a quarter full (3/4 empty) the van would shut off after a short distance, then after sitting for a while would start up again get me a little farther then shut off again. i ended up changiung the fuel pump cost me almost $300. if this simple test shows no results the you got electrical problems, check distributor, and surrounding cables. good luck. also check your fuses could be dirty!

You need to use a LED type test light for the injectors or a Bosch style Noid light for the injector. To test the cam/crank sensor signal you either need a scanner to read them or a lab scope to show you a signal. The pickup plate in the dist handles the injector timing, the crank sensor provides a RPM signal. They both feed the computer information for ignition timing. Good fuel pressure, injector activity(Noid), and good spark out of the coil. The coil is what I replace the most of.
