1988 Ford E-250 Crank No Start No Fuel Power

Asked by Oct 08, 2017 at 05:08 PM

Question type: Maintenance & Repair

I replaced the ignition switch. And still no
power to the fuel pump and if I manually
put power to the fuel pump it still doesn’t
start so it has to be something with the fuel
injection and fuel pump wiring. Because
we do have spark. And there’s no buzzer
either. No start up lights. But I have
checked all fuses in the kick panel and
they are all good. Please help!

the pump needs a good ground too , do you hear it come on when you hot wire it ? is there fuel pressure at the rail ? Get fuel pressure to the motor in a normal way then proceed

I have my fuel pump just like the factory at the moment and it has no power going to it

there's a collision kill switch for the fuel pump , I think a red button under the dash passenger side , give it a try , perhaps a relay is involved also , you'll need a multi tester to see whats getting power and ground and what isn't , a handy item to have if you're going to do your own work

I checked the collision fuse and replaced the fuel relay yesterday but still no luck. I got the vans startup buzzer to come on and I also was able to get the blower motor and windshield fluid to work all of which weren’t working when I got the van.

thats an old vehicle and if it sat around for a while the rodents may have set up house and chewed on some wires , water can leak through the glass and cause problems , just cause it's old don;'t mean it ain't good

Yea I just can’t figure the issue out. If I run a wire to the fuel pump and it is pumping is there also a wire going to the fuel injection keeping it from letting any fuel in?

is it a TBI system with a carburetor type thing on top with a single injector ? That gets a signal from the ECM from possibly a crank sensor , to "fire" it'll pulse shooting fuel down the throttle , Thats why you can't just run a hot wire , the computer runs it all and an improper signal , or none at all , may cause it to shut down other things . That's why I say "do it normal " because you can't second guess these systems , there's always surprises , the best thing to do is start at one end of a circuit , do you have a tester ? Scan for codes , I don't know exactly how , I think there's a junction under the hood and by bridging two terminals the dash will flash codes ,check U toob , It could be a bad ECM who knows ?

Did you figure it out I have same issue in 1992 E250
