So I bought a ranger on craigslist for 500 bucks, its got some issues but I thought i would be able to figure out most of them on my own. Turns out I'm having a really hard time finding wiring diagrams for it (I know of the evtm but am having a hard time finding one for an 87) I've been reading tech articles and such but I'm hoping I can get some more specific help.
It is a 1987 Ford Ranger xlt extended cab 4x4 with dual tanks and a 2.9l v6.
So, things I know are wrong with it:
1. PO said he hardwired the fuel pump to the key so if the key is on the fuel pump is on, I think the inertia switch is tripped but haven't reset it yet as I want to remove the hardwiring first.
2. I think it is running very rich, it barely runs, sounds really rough and everything smells like gas when it is running, can't see any leaks anywhere but the oil smells like gas and I checked the vacuum line on the fpr and it smells like gas though doesn't seem to be wet from gas, I think i need to replace the fpr.
3. The alternator is bad, this is something I don't need any help with I don't think, I've replaced alternators on 4 different cars and it looks fairly straight forward. if there is anything odd about it compared to other cars, please let me know.
4. There are a lot of wiring issues, PO has a bunch of crimp connectors "fixing" things, the wires after the connectors don't match the ones before them, the previously mentioned hardwired fuel pump , and I don't think the ecm is getting power, KOEO the check engine light doesn't turn on.
The first thing I want to do is fix the wiring and then change the oil and fpr and try to get it running well (hoping wiring and fpr will have it running better anyway) so i'm going to post some pictures of some problem areas and hopefully you can let me know where wires are supposed to go, post pictures of the same area in your truck with everything correct, let me know what is supposed to be plugged into loose connectors or point me toward some wiring diagrams that will have correct wire colors and layouts.
Thanks in advance for any help, I know I'm asking a lot and I appreciate any help offered.
Picture 1: I think this is where the hardwiring for the fuel pump is happening, not positive though
this yellow wire goes from the fuel pump relay (I think, it the relay with the green base) through a fusible relay where it changes to a blue wire, has a blue crimp connector, stays blue (yay!) and then connects to the starter solenoid (I think that's what that is) then has another wire coming off of it that goes to a blue crimp connection and ends. wanting to know where that yellow wire from the relay is supposed to go if its not to the starter solenoid and if it is the starter solenoid where it is supposed to go after the crimp connection where it currently ends. Also pictured is a black wire with a red stripe connected to the negative battery terminal, just want to make sure that is supposed to be there, it goes into the wiring harness.
Picture 2:
I think there is probably supposed to be something plugged in here. Those lines on top are probably supposed to go somewhere as well.
Picture 3:
this connector is probably supposed to be plugged into something, it has a red wire, a black wire with a yellow stripe (I think its yellow, hard to tell) and a red wire that I think has a yellow stripe, its hard to tell if there is actually a strip or not, it is on the passenger side near the fuel pump relay, obd1 thing and ecm relay and such
Picture 4:
this black wire with a white (or possibly really faded blue) stripe comes out of the wiring harness near all of the wires for the relays by the air intake and then ends
Picture 5:
this connector on the driver's side is probably supposed to be plugged into something, it has 3 holes in the end that I'm unsuccessfully trying to show and comes from the part of thw wiring harness that goes over by the windshield washer fluid reservoir
Picture 6:
this connector comes from the wiring harness on the driver's side and isn't connected to anything, it has a white wire with a pink stripe (I think the stripe is pink, hard to tell) going into it
Picture 7:
This yellow wire with a pink stripe ends after coming out of the pictured connector on the driver's side
Picture 8:
This blue wire with 2 fusible links comes out of the wiring harness on the passenger side, goes through the fusible links and then ends.
Picture 9:
This connector isn't connected to anything (and is also a bit melted so I guess I'll need to replace it)
Picture 10:
This connector in the glovebox isn't connected to anything, I'm not sure it is supposed to be though
Picture 11:
Are these little wires on these red connectors down by the fusebox under the steering wheel supposed to be connected anywhere?
Picture 12:
Is there supposed to be something plugged in here or something?
Alright, again i know this is a lot of stuff, any help is appreciated, I can't wait to get this thing running well so I can do some offroading with it.
