Fuel pump on my 93 ford ranger will not run and the check engine light will not come on when you turn the key on. Just put a new fuel pump on the truck. Any ideas on where to go next???

Just because you can hear the pump run, doesn't mean it is supplying enough fuel to properly operate the injectors. You need to check the fuel pressure at the fuel rail. If you have at least 45# of fuel pressure at the rail, you need to make sure that the injectors are metering. If memory serves me, I believe they are fired by the pickup in the distributor, but 93 is right when they were phasing into DIS ignition.

Have you checked the fuel pump cutoff switch? Do that first, make sure the red button is seated into the switch, if it is tripped it will click when you push the switch. Also you're aware the pump only runs when the key is held to the engine crank position and of course when the engine is running, with the key just turned on the pump will not have power.

OK, when you turn the key to on, it will start the pump for about 2 seconds-this is just to put pressure in the lines and in the fuel rail for easy starting. If key is not turned to start, pump will shut off after 2 seconds. But when cranking in start, and when engine is running, the pump is on full time.
If your pump runs longer than 2 seconds with key only in on position, you have a fuel circuit problem. It very well could be a bad fuel pump relay staying on. Or it could be a computer problem signaling the relay to stay on longer. Try a new fuel pump relay first and see if that was the problem.

Change fuel filter. Check fuel pump in tank.

replace fuel filter could be plugged

Check your battery, especially if it is older. Had same problem with 2007 Ranger.
It seems that there may be enough power in the battery to turn on daytime running lights, instrument cluster etc., and turn the engine over, but during all that, there may not be enough power left to adequately power the fuel pump.
After replacing a 9 year old battery, I had no more problems with my fuel pump (almost 1 year since battery was changed and no fuel pump issues).

REMOVAL & INSTALLATION NOTE: To gain access to the fuel pump, it is necessary to remove the fuel tank.

1. Depressurize the fuel system and remove the fuel tank from the vehicle.
2. Remove any dirt that has accumulated around the fuel pump attaching flange, to prevent it from entering the tank during service.
3. Turn the fuel pump locking ring counterclockwise using a locking ring removal tool and remove the locking ring.
4. Remove the fuel pump and bracket assembly.
5. Remove the seal gasket and discard it. To install:
   
6. Put a light coating of heavy grease on a new seal ring to hold it in place during assembly. Install it in fuel tank ring groove. Fig. 1: Fuel pump and sending unit used on the Regular Cab Ranger pick-up
   Fig. 2: Fuel pump and sending unit used on the Super Cab Ranger pick-up

7. Insert the fuel pump assembly into the fuel tank, then secure it in place with the locking ring. Tighten the ring until secure.
8. Install the tank in the vehicle.
9. Install a minimum of 10 gallons of fuel and check for leaks.
10. Install a pressure gauge on the throttle body valve and turn the ignition ON for 3 seconds. Turn the key OFF, then repeat the key cycle five to ten times until the pressure gauge shows at least 30 psi. Reinspect for leaks at the fittings.
11. Remove the pressure gauge. Start the engine and check for fuel leaks.

Great SUV, I have the same model; for Ford Ranger/Explorer/Mountaineer 1991-1999 check this procedure to Fuel Pump - REMOVAL & INSTALLATION...

Hope help with this; remember comment and rated this help. TY for using Fixya.

check the fuel filter to see it that is plugged up. When turning the ignition key to on only without trying to start the engine you can hear the fuel pump running for a few seconds if working. If not the pump is bad

i was once pulling a trailer with a ranger when it suddenly lost power and the engine died. turns out the problem was with the fuel shut off inertia switch. the switch is supposed to activate in case of accident. on my model the inertia switch is located in the passenger side under the glove box. dont know where yours is located. once you find it, just push the button and see if it resets. good luck.
