Just replaced the fuel pump on my 95 explorerthe truck cut off while i was driving and wont start up again

start with is it a fuel delivery problem or no spark and go from there

Oil pressure sensor is not latching the fuel pump relay....the oil pressure sensor is old in the 95 and needs to be replaced anyway..........Also make sure oil level is correct...a low oil sensor may be disabling the ignition......

Anti-theft system ! do you have a SECURITY light lit on the instrument cluster ? You test fuel pressure before replacing pump.

Run tests. Fuel pressure correct? Spark at plugs when cranking? Fuel injector pulse working? Compression test?

Definately sounds like the fuel pump

Maybe the wires are grounding check for wires chaffing

I think what you have going on here is a failing electric fuel pump, this is what they do when they are worn out, it is a rotary pump and the rotor sticks due to worn bearings. To confirm this get a can of spray starting fluid from any auto parts store, next time it won't start spray it into the air intake hose to the engine, if it fires right up you have a bad pump. The fuel pump is located inside the fuel tank, remember to also replace the fuel filter when the pump is replaced. Also check the connector to the fuel pump cutoff safety switch for signs of melting, replace the switch and connector as needed, this is caused by a defective fuel pump drawing excessive current.

Heat related ignition failures are often caused by a dying coil.

you might have a pinched fuel line some where>

Try checking fuel pressure again with a guage on the fuel rail. If you still notice the pressure is low and you know the fuel pump is good, the fuel pressure regulator may be bad. Sometimes you can tell by unplugging the vacuum hose from it and if you see gas that means the diaphram is leaking. If everything checks out with the fuel system a bad EGR valve or EGR valve solenoid can cause cars to sort of stall under half throttle. Good luck and keep me posted.
