ok so i got the module out, it wasnt to hard and it turns out it was held in with 5.5mm bolts, so now i am wondering if there is anyway to see if its faulty or not using a volt meter or something like that

i just got an 89 bronco II it has the same problem as 86 bronco II no power to injectors. previous owner changed computer pickup coil and control module. still no power to injecters runs on starting fluid feul pumps only run when hot wired also changed fuel pump relay

so have you got it running yet bill?

no just got it haven't had time to work on it yet. lf l find the problem i will let you know

got the module tested and it passed multiple times

If it starts on starter fluid shouldn't the module be good? Have you pulled an injector to see if it's spraying right? Sorry if you already went over this, I'm just trying to start at square one in case we missed something simple. You have rotation, ignition,compression, it seems getting fuel to the fuel injectors is the issue ( not trying to state the obvious here just recapping) just one more thing, how old is the gas in the tank?

the injectors aren't opening, no pulse. it has fuel pressure at the rail.

In the schematic I see a couple in-line fuses, have these been checked, it sounds like you've had a few shorts which will cause these to blow.

there isnt any pressure at the rail unless i hotwire the pumps

is it runnin?

well???

got that bronco home today. it is an 88 there are 3 wires to the negitive post one big one to motor block. one small one to header panel. the other one going towand the fender has a plug in it. it is black with a green stripe leaving the plug.just like ranger dave said. on mine the plug was bad. i rewired it and it statrd right up. it is the ground wire for fuel injection

thanks for the good info Ranger Dave
