I HAVE AN 87 FORD RANGER REPLACED BOTH FUEL PUMPS AND I STILL CANT GET THE FUEL TO THE FUEL RAIL TO START THE TRUCK WHAT MAY CAUSE THIS

at idle should be in the area of sixy pounds at Shraider valve on fuel rail
any lower than that ck filter and pump any higher ck vac line to regulator for holes/cracks or posibly failed regulator

Check to be sure you are getting fuel to the fuel rail. The fuel filter could be stopped up. Also I would check the nertia switch to be sure it has gotten turned off. This switch is the fuel shut off switch.

It can't be filled up because it leaks, or won't take anymore gas? Check the hose from the fuel filler to the tank for kinks or restrictions, if you have leaks, fill it up and trace the leak. Either problem will cause EVAP codes, hard starts, and cause vehicle to die.

Hi, I believe you have a leaking injector(s). Check and/or replace. Good luck.

Without seeing it it is a hard thing to diagnose. You could have an injector leaking, possibly a fuel line. Do you smell gas? Sometimes with fords around the fuel filter leaks because of a broken clamp. The o rings around the fuel injectors could be leaking, or one of the rubber fuel lines. If you go off road alot, you could have a pin hole in one of the rubber or metal lines. Check and get back with me and I will do the best I can to help. Hope tis helps.

somethings leaking, probably one of the hoses you disconnected at the fuel tank. as the 2nd fuel pump is in the fuel line and much easier to get to. that kind of drop in mileage would have to be a leak.

the gas goes bad in one year (this comes from the American institute of petroleum), the fuel injectors are most likely damaged and the electric fuel pump and filter will most likely need to be replaced before it will start. so drain all the fuel put in at least 5 gallons of clean fuel, add one can of BERRYMANS CHEMTOOL and hope for the fuel pump to work and the injectors clean themselves out

there are 2 fuel pumps, a low pressure in the tank and a high pressure on the frame rail. the high pressure pump is probably bad. Check your relay and inertia/cut off switch first.

got 1987 ford f-150 no power to fuel pump, checked fuel cut off swith seems ok, new fp relay still nothe can I run hot wire to pump and if I can which ones the hot wire??

There is a fuel cutoff switch on the passengerside floorboard, towards the right kick pannel, there will be a little red button on top of it, check to see if that is tripped, also when you turn the key to the on position listen to see if you hear the fuel pump prime up, just a short buzzing noise from the underside of the cab, if you dont hear it, that is a good indicator that your fuel pump maybe bad, i would also check the pressure at the fuel rail, chrome or black colored bar located near the fuel injectors.
