94 s10 i have no fuel pump or inj pulse when key

Have you checked for power to the pump from the fuel pump relay.After the key has been off for 10 seconds,turn it on and there should be a short 2 or 3 second pulse of power from the relay and you should also hear a click there.If there is no power pulse,is there power to the relay?Remember the relay only primes the fuel system and the oil pressure switch keeps power to the pump when it sees oil pressure.Is there power at all times to the oil pressure switch?On these vans the wire from front to the pump can go bad,quite a few have had a new wire run for the pump over the years.A great van.

Click on the link, there is no reset switch. Note the diagram. Voltage for load side of relay comes from fuel pump/inj fuse, probably goes hot with the key on. At fuel pump connector, gray wire is voltage, black is ground, need both.
I don't know what testing you have done? Engine cranking did you visually check for spark at the plugs? Do you have fuel injector pulse? Any applicable trouble codes?

Fuel pump relay may be weak. Try removing the connector from the oil pressure switch and connecting the terminals together so as to bypass the switch.
if this works, replace the relay.

There's no use guessing anymore, have a quailfied independent repair shop diagnose and fix it. Stay away from chain stores. The money you have already spent guessing would have it fixed by now. Ck the ASD and Fuel pump relays, and go from there. Is there any tropuble codes in the ecm? On some of these you can turn the ign key on-off 3 times and read codes from the ck eng light.

Fuel Pump Relay Circuit...
There is an Oil pressure switch in this circuit that disallows the relay to complete the power supply to the fuel pump. It is for safety purposes , it senses engine oil pressure upon cranking of the engine and then completes the ground circuit to close the relay sending voltage to the fuel pump at start up, and also functions as an engine kill if you loose oil pressure opening the ground circuit which in turn opens the contacts in the relay shutting off the power to the fuel pump.... Invest in a vehicle specific repair manual with wire diagrams... hope this helps..

Fuel pump, you have to have press in the rail to fire all injectors- she will run on ether but not good for her. Ck your pump and any related fuses,relays,wiring.

There needs to be 60 PSI of fuel pressure in the system to have the fuel injectors to work. There is also a fuel pump relay on the fire wall just left to the brake booster, There is two relays there, i just can not remember which relay is which but try switching the relays with one another. Also check the fuses to the fuel pump and ECM, and the fuel pressure from the shredder valve. Good luck and keep me posted, not a bad Idea to also replace the fuel filter, and that is located at the inside frame rail under the drivers side.

Inside the distributor and on the ignition module (7 pin) one of the wires to the camshaft pick-up had pushed out of the connector when I hooked up the new module. I reinserted the wire and problem was solved.

At the fuel pump relay you should have 1 full time hot wire. 1 hot wire when you turn on the switch. 1 ground, and the other wire goes to the pump. Test the ground to be sure it is good. If so then jump a hot to the one that goes to the pump and see if it runs.If it does then you have a bad relay or ECM. You can swap the relay with another of the same # from tour fuse box to test it.There is also a ground on top of the frame near the filler neck, check it too. Good Luck

Fords have inertia fuel cut off switch. You need to check that first. If you dont have fuel. If you have fuel and no spark you need to check for inj pulse to injector. Make sure no fuses are blown. If no spark and no injector pulse then replace cranksensor.
