I did it I converted my 86 4R to a pickup because that was the only way it would pass state inspection - tailgate issues. Those of you who are purists, have delusions of grandeur or prissy motorhead values would probably hate it. I just pulled the cap off the back, made an insulated cab back...

My 86 has 311k on it and runs great. But it has needed some work over the 2 years I've had it - front axle, e brake, calipers, radiator, and miscellaneous hoses and geegaws. I got mine with 302k on it, mostly use it locally for hauling. 2100 bucks seems like too much, tho. I would ****er if I...

I copy that. But what I'm talking about is the gap between the signal rotor and the pickup coil projection which the manual gives a spec for. Its sort of like adjusting points on old cars. I know how to do it, just not how to get the relationship set up to make the measurement.

Anyone ever fabricated one of these or know where to get one? I made one but the piece that fits into the hole in the bottom of the e- brake handle keeps letting go. I see plenty on line but they are all rear cables. Looking for advice on how to make the little retainer- I used copper...

I know in theory how to set the air gap on the distributor, but when I went to actually do it I find that the point of the signal rotor is not lined up with the pickup coil projection as shown in FSM. Rotating the motor moves the rotor but not the signal rotor, which seems to be fixed. Do you...

I don't know except in theory, but if the harness that's burnt includes the signal wire from the ECU to #2 injector, it might not fire. You can probe the back side of the injector electrical connector with a test light and see if you get a flash everytime the cylinder hits. which would mean...

The fans got a coolant switch that turns it on and off when the engine coolant gets hot enuf. Thats usually the problem in a case like this. Trace the fan wires back- one should go to a sensor in the engine block, which would be the switch. Usually you can unthread it with a deep socket, then...

It could be a big, expensive surprise. That you have to pay for.

I dont know the answer to your first question. As to Question 2- it is possible for the fuel injection system to lose pressure when sitting, which could produce the problem you describe. You could have- a pinhole leak on a fuel line defective fuel pressure regulator- usually hole in...

The best thing is the Factory Service Manual (FSM on this forum.) Search this forum for a link to download it free or try 4crawler.org for a place to download it. There may be a diagram of the vaumn lines under your hood. Basically, check all the rubber tubes that run to the throttle body and...

Look for vacaum leaks. Look especailly for leaking injector seals. You can spray a soapy water soloution on the injector seal area and see if it gets sucked in. Some people spray ether or starting fluid and listen for a spike in RPM- I wouldnt suggest it because of danger. The fact that...

dude- that tailgate is the weak spot on all first gen 4rs- its hard to find an intact one anywheres it snows. It will rust out quick. Check your rubber seal, but more important, take off the access panel on the back of the t-gate and see what condition things are in. Spray some WD40 on...

The knock sensor does what it says- it senses knocks. Whenever the engine knocks, due to lugging, out of time, poor gas or whatever, the knock sensor sends a signal to the ECU ( engine computer) to adjust the engine tuning to eliminate the knock. Most EFI vehicles have them. They are easy to...

Good luck finding a tailgate. They all rust out, especially up here- I'm in Northern New Hampshire. I rebuilt my tailgate to pass inspection, using whatever sheet metal and fiberglass I had on hand. Also had a nonfunctioning rear window wiper system. I took it out, so now I can sell you the...

I'd look for loose/broken electrical grounds to injection components- like you hit the bump, maybe you broke something loose.
