PLEASE HELP!?!?!?!?!?!

ok so i have spark but i dont hear any of the fuel pumps come on, what could that be? and another thing, is there supposed to be a fuse block by the air cleaner? and if anyone knows a good website for very clear wireing diagrams that would be great and by the way i know both fuel pumps work becuase when i manually put power to it the both come on and give the fuel rail more then enough pressure so let me know what ideas you guys have, anything would be helpful at this point, i just wanna get it running and on the trail so let me know what you think

look at the - cable on the battery, there should be a small black wire with what looks like a inline fuze holder.make sure thats connected. when you manually power the FP it will run?? it also could be the inertia switch

i have reset the inerta switch and that didnt help and no when i put power to both pumps it does not run, and as for the black wire that looks like a fuze holder, well the only black wire i see that comes off the battery is another ground wire, other then that nothing

Dave makes good points I would also get a visual inspection of the wiring harness to the pumps and check with volt meter, to see if your getting power to the pump.

[Ranger Dave]

so you have pressure at the fuel rail and it still wont start,hmmmmm, will it run on starting fluid??

[86broncII]

yes it will start on starter fluid and the only way i get pressure to the rail is when i do it manually

[Rockcrawler]

make sure your ecm relay is working

[Ranger Dave]

it could be the relay but,it it has fuel pressure(hot wiring the FP) it should run.it runs on startin fluid. id say the injectors arent gettin power or there plugged. maybe try another computer?? and make sure all the grounds are hooked up

[Ranger Dave]

theres two wires that come off the -post. one goes the the radiator support,the other is for the pumps. you hear any clicking when you turn the key on?? i think ya dont

[86broncII]

ok so yeah there is a new computer in it and that wire is rerouted to the positive side of the stater solinoid or whatever, so that sould be to the negative side of the battery?

[86broncII]

anothing thing i was confused about, there is a red plug that looks like it needs to go some where but i cant find anywere where it would go, it has 3 wires that go into it but i cant fine the other end to it, is this important?

[Ranger Dave]

so that sould be to the negative side of the battery?

mine is there on my 86,87,and 88.not sure on my 90. mine all run

if thats the problem with gettin the pumps to come on then it still might not run. cause you said theres pressure in the fuel rail(when the FP is hot wired) and it didnt run.

[86broncII]

ok so i did that and still nothing no clicks and none of the fuel pumps come on

[Ranger Dave]

well. hookin a ground wire to + isnt good. could of cooked the FP relay. you still have other problems. with the FP hot wired did you push open the fuel pressure test port??? the valve stem thingy
