1987 Other Ford Models engine control module wiring relay

Ok so do you have power to anything when you turn the key on? Will it try to crank at all?

OK lets start with tying to get power. Now near the battery off the positive cable there is a couple of fuse links make sure that they are good and not burnt. So the battery cable goes to the starter relay and off the starter relay there is a brown wire and green wire those are the wires with the fuse links that I would like you to check. Let me know what you find and we will go from there.

Ok near the battery there is a solenoid (see pic). I need you to check it for power. Now the battery cable from the battery (+) side goes to it should have power now there should be no power to the other side. Now I need you to crank it over and see if there is power to the other side and check the S term and then check the I term. Let me know what you find.

Ok if you would include pic as that is now how it should be it grounds through the base. Should be wired as such. Battery to solenoid (large post). Ignition switch to solenoid (large post on battery side). Solenoid to start (other large post). Ignition switch to neutral saftey switch to solenoid (small post). Base is ground. This is according to the wiring diagram for you car. So what I would like to know is if there is power to the small post when you try to crank it over. Let me know what you have there. Thanks.

So I take it that it is cranking over now but still not starting? If this is correct then if you would remove a spark plug wire from a spark plug and put a philips screw driver in the end and put it near metal (valve cover) and crank it over and see if there is spark.

Ok I just like to make sure we don't miss anything. Now as for power to the pump should be as such. You should have power to the pump for about 3
seconds when you first turn the key on and then when cranking and running. Did you check fuse number 20 in the fuse box? This is the fuel pump and fuel pump relay fuse. Let me know if the fuse is good and we will check the relay next. You do have a digital multi meter to do the tests?

Ok so there is no power to fuse 20? If there is no power to that fuse then we need to determine why as this is what powers the fuel pump. Have you checked the inertia switch? The inertia switch is in the spare tire well. It has a button on the top push this button and see if it starts. Here is a pic of what one normally looks like.

Ok did you push the button on the fuel pump reset to make sure it didn't get bumped? Check fuse 11 this supplies power to the fuel pump relay. Let me know what you find here. If this is good then I would like to check the fuel pump relay it may be no good.

Ok on the fuse box in the car there are relay's. Now relay number 4 is the fuel pump relay (see pic). What I need you to do is turn on the key as you have you hand on the relay and does it click? If not then I need you make sure there is power to the relay should be blue wire. Then make sure the brown wire with the white stripe has power. THen make sure there is power coming out of the relay on the black wire with red stripe, this is how the power is sent to fuse 20 to power the fuel pump. If you have power to but no power coming out of the relay then replace the fuel pump relay. Let me know how it goes.

OK first off thanks for sticking in there with me I know this is taking a bit but I just need one more thing. Could you include a pic and term numbers of the relay so I can tell you how to test it to see if it is working? Thanks
