My 1986 Ranger 2.9 starts only when I spray starter fluid into the air intake. It does stay running and it drives fine. The engine will not fire up unless I do this process. I have cleaned out the fuel rail, fuel injectors, purchased new fuel filter, and tested fuel pressure (which is good).
View 9 RepliesLooking for the wiring diagrams for 86 ranger fuel system. I replaced the fuel pump relay after testing and finding that it was bad, still not getting fuel. I want to test any fusible links or anything else that could have gone wrong before I throw another part at it.
View 1 RepliesI have a 2000 Pontiac Bonneville ssei (Supercharged) 3.8L V-6. I had a issue with the fuel injectors now that problem is fixed. I can't get the car to start on it's own. I and a auto garage have replaced the MAF,MAP,Camshaft Pos Sensor, Crankshaft POS Sensor, FPR, ICM, IAC, Someone had the TPS in wrong and I was missing 5 volts at pin B of the TPS. I corrected that and now it's ok. The engine cranks but it will not start on it's own, I have about 54 psi on the fuel rail.
The ECM was replaced by the dealer before i fixed the fuel injector problem but that did not work so the original is back in place. The car runs like a top after I shoot some starting spray down the intake and will run until I shut it off. I try to restart it and it won't start until I spray it again. I am very careful not to spray on the MAF sensor. Even with that being said I use Electronic spray cleaner to start it. All Sensor wires have been checked with the exception of the crankshaft position sensor which I'm going to do today going to the icm.
I just wanted to make sure. I'm using starter fluid which I heard causes a bigger explosion and can damage piston rings and whatnot so I figured can I just spray some gasoline into the air intake?
View 19 RepliesOkay so I have a 2004 Dodge Ram Hemi, the truck was running fine all this weekend and was fine this morning. Went out at lunch and used the automatic starter button while walking to it and wouldn't start. It turn over and wants to start you can hear it trying to catch but it won't catch unless you put some starter fluid in. Just changed all 16 spark plugs, all 8 coil packs, wires and 2 valve springs about 2 weeks ago have been running fine since and now this. What it could be?
View 15 RepliesBut here's too my question. I recently bought a 2wd Ford ranger 2.9 automatic. Bought not running. They said it wouldn't turn over that there was something wrong with the starter. I figured it was the neutral safety switch turned out it was there's a wire broke on it. I can get in there touch the wires together and it'll turn over. But I can't fix it because the shifting linkage is In the way. I'm wondering how too take it off. I've never worked on one before. And I don't wanna mess up my gears.
View 1 RepliesI have a 1986 F150 6 cyl, dual tanks, no AC, manual fuel pump. Just recently, I have been having issues with the tanks. At first it seemed like the back tank was siphoning from the front tank. Now I have fuel coming out of my front tank filler neck. When I open the back tank gas cap, there is enough pressure to spray me with gasoline. I am not familiar with the fuel delivery system of my truck ...
View 2 RepliesMy pops has a 86 ranger with a 2.9. And what its been doing is, it will start up just fine then u give it a minute and itll start to run very rough like a bad miss fire, then if he revs it up for a bit. It will clear out and then run just fine until he starts it up again and it seems to do it more the colder it gets and it smells very rich. Iv checked the injectors and there fine, what other things could it be ? O2 sensors oorrr
View 5 RepliesI have a 1994 Ford 460 motorhome with a intank fuel pump that quits when it gets hot. so I was thing of butting a heavy duty in line pump on and just pull it through the old pump can this be done safely. Or is it best to drop the tank and just put a new fuel pump in.

View 2 RepliesI have a 1986 27ft Class C RV on a E350 chassis, 460 ci with about 140,000 miles on it. I inherited it when my Dad passed. I live in the southwest and I am have trouble with it, it seems to be a fuel supply problem, I think?
It runs fine on level ground, but we tried to go to the white mountains this weekend and could not do it. On an incline the engine would start to starve for power. At times we could only drive at 25 mph! It kind of seemed like it was running out of gas, if I tried to give it more throttle it would just die or fall on its face, if I let off the pedal and gave it gas again, it would run for a bit and then do the same again. We were lucky to get it back home. I replaced the electric fuel pump (on the side of the road) during the trip, but that made no difference.
The engine ran cool the whole time! it has only one 40 gallon tank. I can find any other fuel pump on it. but don't understand all the lines going to and from the gas tank either?
I noticed there are these silver metal tubes that feed off the exhaust manifold up to a cylinder looking thing on both sides of the block. One of the tubes is broken from the ex manifold and the manifold is plugged. Not sure how this got damaged or what this parts function is but was wondering if this could be a problem ..
What to do next. Engine is running on 4 cylinders, #1, 4, 5, 8. Had a mice nest on top of injector #2. Removed mice nest. The mice had chewed through wire for #2 injector and caused bear lead rubbing on the block. One lead rubbed through. Repaired, splised in a wire. Also changed rotor, rotor cap, all sparkplug leads and plugs.
Troubleshooting.
Compression on all 8 cylinders measured to be above 160 psi.
There is spark to all 8 cylinders, including the other 4 cylinders, 2, 3, 6, 7 that is nor developing power.
Fuel rail pressure is 35 psi on idle and spikes to 43 when reving the engine.
The fuel injector resistance all all measured injectors are the same (about 14.8 Ohm). Measured injector # 1, 2, 5, 6, 7, 8. Injector # 3 and 4 is hidden and require too much disassembly. Visual inspection deems wire for #3 and 4 injector to be ok on top of block.
Electric impulse (tested while engine was running) to injector # 1, 5 and 8 are ok, used test lamp to see that there are electric impulse to the injectors. Injector #2, 6 and 7 does not have any electric impulse. Unable to check electric impulse to # 3 and 4. However cylinder #4 develops power. Used moving the sparkplug wire for cylinder #4 to verify that is is developing power.
What would my next step be? Where should i look next?
1. Where is the control module and is it likely to fire to only 4 cylinders
2. Could it be an wire in the pickup element, under the distributor. All wires seem intact.
I have an 86 F150 that is idling rough. It used to cut out on me until I replaced the fuel pressure regulator. I have read in other posts that the problem for my rough idle could be leaking injectors. When I replaced the regulator I found a bad injector. My question is that if I check my fuel pressure, with the new regulator, would the only way I would lose pressure be that my injectors are leaking?
View 5 RepliesMy engine is running rich, flooding? My truck is a 1986 F-150 302 EFI. The engine idles rough, black smoke and soot comes out the exhaust pipes, and black soot on spark plugs. Symptoms seem to disappear if I throttle the engine and hold it, but as soon as I release the throttle the symptoms reappear and in most case causes the engine to die. These symptoms have just started a week ago. What the problem is.
Fuel injectors are cleaned and rebuilt. New plugs and wires. All new fuel pumps and filters. New air filters. New fuel pressure regulator. New dual function reservoir. New 3-piece timing set. New O2 sensor. New EGR Valve and sensor. New idle air control valve. New distributor, cap, and rotor. New ignition coil. New high volume oil pump. New alternator. New pcv valve. New knock sensor and air charge temp. sensor.
I have a 86 ranger 2.9 5 speed. A few days a go I replaced the front fuel filter and all seemed ok. Last night on my way home the truck quit and I had to have it towed home. Now I find both pumps don't seem to be working. What would make me loose both pumps??
View 11 Repliesits 1986 Ranger with a 2.9L V6 Auto 4x4, well to start with it seriously over fueling also it idles very roughly and even stalls out sometimes, when I'm trying to hold it at a speed it acts like it is missing (I guess that's from over fueling as well and it also pukes out lots of black smoke, it goes through way too much gas for a V6), but when I speed up fairly hard it acts fine until I try to maintain speed again, I have already put a tune up into it and a new EGR as well a fuel regulator and how to fix it?
View 14 RepliesI have a '77 F250 with a 460. (Under edit) It has a holley 750 carb. (under 2 years old). It ran fine for about 2 years and now all the sudden it seems to not get enough fuel. I have a clear fuel filter on it and you can see that it is full of fuel when I first start it up. Just letting it sit there and idle after about 5 minutes it starts to show air coming through the lines and it gets worst the longer it runs.
If I take it out on the road and drive 55 it will be about 1 or 2 miles and it acts like it's not getting fuel. I stop and open the hood and check the filter and it is empty. What could cause this? I took it to an old Ford machanic and he has checked the fuel pump, fuel lines, sending unit, and gas tank. He is at a loss. I am no mechanic, but I am mechanicly inclined. I can't see it would be that hard to figure out. What do I do?
Ok I finally got my truck to start, but it dies instantly. I had a friend of mine who is a mechanic look at it and he said gas wasn't filling up the front bowl, but gas was pumping? Could something have happened when the carb was rebuilt?

Ford has ordered a fuel pump, I am thinking it could be the
-Throttle position Sensor?
-MAF sensor?
-fuel pump?
It puts out code p0191 for low fuel pressure. Ford is scheduled to install new pump in am, but I don't want to spend a grand if it is just the TPS or MAf?
My gas gauge is not working on my 2000 F-150. We have already replaced the sending unit and still nothing.... The Fuel pump is working....
Second, When reading the computer what is Lean Bank 1?? Is it dirty fuel injection??
Thirdly, When I start the vehicle....WHY would I get a rattle in the brake fluid junction box????
