The relay should be on the fire wall. A oval shaped grey relay about 2.5 in tall. Good Luck

Checking power for fuel pump

Do you know what a fuel pump relay is ? You can check B+ Voltage an control at the relay > Find the relay in the under hood fuse box . Pull the relay out an look on the bottom , you should see four sets of numbers 30,87 an 85,86 ! 30 an 87 are the power side ! One of these will or should have B+ voltage , the other goes to the fuel pump . You could take a piece of wire an jump 30 an 87 , in the fuse box where the relay plug's into . The fuel pump should run ! The control side 85 an 86 , one will have B+ voltage an the other will be open circuit , unless you crank the engine ! The PCM supplies a ground when an input from the crank sensor is sensed. Videos on youtube on trouble shooting an testing fuel pump electrical circuits .

87 s 10 well not run it is not getting gas to the injected

Make sure fuel pump is cylcing,you sould hear pump when you turn key on. Check fuel filter and relay for fuel pump. If still won't start try banging tank hard 4 or 5 times with key on and see if you hear pump cycle.If that works fuel pump needs replacement. Also try pouring some gas in intake to see if it fires up.

I was running this car in my driveway, when it died all of a sudden and will not restart. I find that there is no spark, and the fuel-pump is constantly running when the key is on. Help!

Hello Ford Cobra.
Strange the fuel pump stays running as soon as the key is on.
This is leading me towards a possible relay problem that is also affecting the power relay that powers up the injection system.
Is there power to the ignition coil momentarily as the key is turned on?
If so the power relay is working and will lead to the next diagnosis step.
Keep me informed.

?87 F-150 5.0 stalled and won?t restart. Electric

Is the fuel pump inside the fuel tank? If, so, you could try disconnecting the wire harness at the tank, and hot-wiring the fuel pump directly to a 12 volt source, in the correct polarity of course! If the pump runs, your problem may be a fuel pump relay, or a wire problem or connector problem. If the pump does NOT run, post that info. There may be a way around the problem!
