Ford Ranger / B-Series :: 1991 2WD - EEC Fuse Keeps Blowing
May 8, 2012
My dad's 1991 Ford ranger 3.0 2wd just died on him when he was driving home and I checked to see if the truck had a spark and it did not so I replaced the ignition control module, then ignition coil, then distributor and rotor cap(plug) and I put new plugs and wires on it a few months back too. I also checked to make sure that the timing chain was working as well (while I had the distributor cap off). Then I realized that the EEC maxi fuse was blown. I then found a fourm that said it might be the relay so I replaced the EEC and the fuel pump relays while I had them both out. Every time I put a new 30 amp fuse in the EEC slot and turn the key to start it the fuse blows and the truck won't start. What might be wrong?

Description: It will crank over forever but not start. New timing belt water pump, etc, so it is not timing. tried different fuel pump relay. no luck. new fuse no luck. The radio fuse also shorts and blows when I change it. Headlight does not come on, but the cabin "ding ding ding" sound plays. Marker, turning, reverse, and brake lights work.
CHECK ENGINE LIGHT does not come on during key turn. I may know what caused it or it may not. Before all of this happened, my audio system fuse under the hood blow. It blew again after I installed a new fuse (immediately).
One day, the wires on a portable cigarette light pump snapped and the two wires had been touch. I noticed the truck stalled several times when letting off the gas and coming to a rolling stop. The fuel pump relay makes a click noise when I turn the key

2000 Model, The fuse keeps blowing on this. I thought it was the cruise control fuse because the cruise kept not working and when I replaced fuse it would work. Only for a little though, then I looked at manual and it says the fuse is for the brake position switch. I am presuming this is just like the old days and that is the brake light switch under the dash. They use to have two wires now there is like five. Anyways I do not see any bare wires or anything that would blow a fuse, is it common for these switches to go out or what??

Fuse #41 keeps blowing...scan tool says o2 sensor heater circuit malfunction. Problem is that when the o2 sensors are unplugged it keeps blowing fuse the second I hit the key. Where this short would be? I can't find a wiring diagram anywhere. ( I'm new to this forum and I'm sure there is a sticky somewhere..
DTC codes: P1451, P0743. P0750. P0760. P0765. P1747. P0135. P1409. P0755. P0155

Since last summer my truck keeps blowing fuse 26 and then I have no reverse lights. If I replace the fust its ok for a bit but blows again the same day sometime. The book says its the fuse for revers and overdrive. The overdrive button on the tree shifter stops working too but the truck does not seem to be revving any higher so I think the overdrive itself is fine. I can't find the short but its got to be shorting somewhere...

I recently got a ranger from my buddy and it keeps blowing the EEC fuse in the engine compartment. We have replaced the EEC relay and the EEC power relay. As soon as you turn the key it is blowing the fuse.

I've got an 86 ranger sport and I'm having trouble with the lights. The turn signals work, and ALL 4 bulbs in the back are new. The brake light fuse keeps blowing, and the fuse for the tail lights is good but they won't come on at all. I was told there was a direct short somewhere, does that sound about right? And is there a common place where they tend to short out?

fuse #11 in the battery junction box under hood keeps blowing, the last time I put a fuse in it blew immediately, key was off and lights off. Fuse is for parking lights, dash light and I/P(whatever that is) and switch illumination lights. I have to start following all wires to find bad spot. May just put in piece of metal and watch for smoke...

My 1991 ranger with a 4.0 turns over but will not start. It acted like it ran out of gas put again seems to do ok then it did same thing it sat over night then would not start so I thought I would put some gas in the intake so it starts ran real rough but smoothed after a few minutes ran fine after that next morning same thing no start did same put gas in intake at first no start just turned over didn't even try let it sit for awhile then tried again it fires up ran rough but ran now I get nothing just turns over pulled codes 22and 122 replaced both had ignition mod checked its good new coil pack no change so at this point i hear fuel pump kick on fuel getting to fuel bar but seems a bit week on pressure going to get pressure gauge and see what it says but in the meantime I am loosing my mind...

I recently bought a 91 Ranger 4wd for my son. The guy I bought it from put new manual lock outs on it. every time I take the tire off on either side the hub comes with it! Is there a clip or retainer missing? If so what and where can I get one?

Getting the Banana ready for it's smog test appt at the shop last night (it WAS today) Check engine light had popped on and it had been starting to sputter and surge at the idle occasionally for the last few days so I took a look at the MAF and saw dirty wires. Aha I can fix that, a couple squirts of MAF cleaner, plug it back in and voila! No more light, the Banana ran down the road around the block, over the hill and through the dale like a champ. I shut her down and call it a night.
This morning, hop in and fire the Banana up like usual and all I get is a nice peppy crank over. The Banana has had a bunch (pun intended) of new parts throw at her recently... new battery, starter solenoid, plugs and fuel pump relay and fuel filter. All within the last couple of months.
Out of complete disbelief, I ground on the ignition for a little while and she finally kicked over and sputtered to life. I let her idle a couple of minutes and things seemed fine so off we go. I make it about a block before the Banana starts hiccuping and bucking like something possessed and dies.... kaput.
The Banana has a 3.0, manual transmission and at least half a tank of fuel. Long story short and a tow truck ride home again, half a day trying unsuccessfully to pull a code, any code.... nothing. She will half-heartedly cough and spastically run with ether shots and near as I can tell I'm not getting fuel to the fuel rail relief port. I'm really hoping there is some way to diagnose a faulty fuel pump without having to drop the tank and fish the damn thing out.
I'm not hearing it run when the ignition is turned on but then again I don't think I've ever heard it run. Any other things to try before I replace the pump itself???

My ranger is an 89 but it's got a 91 motor in it, 2.9 V6. When I accelerate it hesitates before actually accelerating which makes me think the TPS is bad. Probed and tested and I got .85V throttle closed and 4.65 at wide open. Specs call for .8V - 4.5V
I'm not sure if there's an allowance of fluctuation, but is that high enough to point out a bad TPS? If it's not the TPS, is the ignition timing off or what else could it be?

1991 2.3 l. Thought I had an exhaust manifold Leak. Replaced gasket. New gasket didn't work. Removed gasket and mounted manifold to engine metal to metal, still and noise. Installed New manifold with gasket. Still same noise. Am thinking noise not coming from manifold. Torqued all bolts to spec. Could it be lifters .

Grandson 1991 Ranger 3.0 v6 69,000 miles We have a long start issue after it has sat for 30 mins. plus. If you open the throttle part way while cranking it will start fairly easily. Fuel pressure comes up instantly when you turn on the key. It runs at 39 psi pull the vac line off regulator it jumps to 49 psi. Fuel pressure does drop to about 30 psi after setting an hour. It kinda acts like it is flooded when it starts. so far we have done a complete tune up plugs wires cap and rotor. The ignition module has been replaced twice last one a real Motorcraft. New fuel pump and filter. Cleaned the fuel injectors with Ford cleaning system. I will replace the coil next and maybe clean the iac.

I have a 91 Ranger V6 4WD with 150K that has been sitting for 7 years. The last time I drove it (7 years ago) to a mechanic, who diagnosed it with a bad head gasket - leaking coolant and coolant in the oil.
What am I looking at as far as a project: besides redoing the head gasket, what else will I most likely need to do given that its been sitting 7 years?

I now have a 1991 ranger 3.0 super cab. I need a step by step walkthrough of how to time it. Keep in mind that I ha the distributor out while turning the engine over so I need from start to finish, including the spout connector. It runs right now but idles high at the start and the. Stumbles down to about 500rpm and sometimes dies....
