Having a chance to try an O2 Sensor Simulator on your truck? I am wondering if they actualy work or if I should just stay away from them. Are there any problems or improvements using a SIM?
View 13 RepliesI have an 85 bronco ii 2.8l, carb, with around 109K on it , ran pretty good, some stubles here and there but found out how to read codes and went from there.... Retreived codes 23, 31 and 84. Checked TPS, had voltage to sig return pin but was low, pulled the carb, bought a rebuild kit while i was at it and redid most of the gaskets but did not take the inner parts of the carb out, put on a new TPS, installed the carb, unhooked battery for about half an hour and noticed it idled very high. Once you were moving the rpm's would drop but at idle would climb again. I ran the codes again and got 31, 63 and 84. checked volts from black to vref i have 4.9 and from black to sigrtn i have 0. i have traced all 3 wires through the bundle and did not see any breaks i know that the green wire goes to the ECM? but i do not know what to check from this point.
View 2 RepliesMy truck just came out of the shop. Was in for spark plug change. My parking sensor button is lighted up with OFF. I tried pressing it but it stays in OFF and no beeping occurring when in reverse and there are objects behind me. What could it be? Fuse?
View 7 RepliesTruck is up in the back country and has quit. It has two factory gas tanks, I can't hear either of the fuel pumps will come on when you turn the switch on. The problem started as an intermittent fuel starvation issue. Truck would act like it ran out of gas then pick up and go again. Switched tanks back and forth but it got worse throughout the day and finally will not start at all. I have listened to both tanks when the ignition switch is turned on but can not hear the pump come on for either tank (switching the selected tank with the switch on the dash). We went through some bumpy terrain just before the problem started so I am thinking maybe a wire might have come loose or got broke somehow. I am asking for wiring schematic so I can check for voltage in the correct place going to the fuel pumps. Both tanks are full of gas so for now dropping either tank is not an option.
View 8 RepliesI have a 94 Fsuperduty with a flatbed and lift that folds up and stores under the end of the bed. Recently while on a job the lift wouldn't go up, so I checked the one fuse I know of in the system and it was burnt. Put a new one in and before the lift reached the top it burnt-out again. It had been working with no problems for months prior to then.

View 7 RepliesI have a idle problem that happens on and off. with my 89 f250 351, it revs at 1900 rpm and when I unplug the vacuum hose to the map sensor it idles about 700 rpm. I've already replaced the map sensor and it does the same thing. i cant find any vacuum leaks anywhere and when i unplug the connector to the IAC nothing happens it continues to rev high.
View 2 RepliesI bought a great 76' SuperCab with a 390 4 barrel Wednesday (the 30th) and while driving around the neighborhood this evening the truck just lost all power and came to a stop. No lights, no engine, nothing and I cruised to an easy stop (fortunately at the end of my own block). I thought I smelled a bit of electrical burn for a moment after I came to a stop but could not track it down before the smell disappeared.
Some early symptoms - on drive home from purchase, the turn signal light function was in and out. The starter was also turning slowly and sounded tired/weak. The ignition switch was a bit loose and previous owner said you had to make sure the key was not all the way to the right or accessories would not work.
Some early checks/fixes- replaced battery and battery cables and checked grounds. Starter began turning stronger and turn signal lights were back. Thought I had it going well.
My 2004 expedition wont go into any gear the shifter will not move I changed the stop light brake switch and a 30 amp buss fuse I found blown and also the check engine light is on now too this was after I parked it I also changed a 30 amp buss fuse I found blown out but it still don't work the only way I can get it into gear is to push the little button under steering wheel...
View 2 RepliesMy 85 f150 5L is parked to far in into my alley.. the last time i saw my keys i moved it up to water the plants that it was tucked almost on top of.
ive been looking for the keys for 2 months.. the truck isnt being driven at all but i think my neighbors are getting mad at it being out so far.
I can get in the engine bay, and i have jumped the starter on our big trucks at work before.. but what wires do i have to join to put the ignition into the run position?
I just bought a used F-350 that was being used by a fire department. They did something to the wiring to where most of the electronics won't work unless the key is in the "ON" position. When I open the doors, the dome light doesn't come on, nor does it come on with the IC dimmer switch, when I turn the key either backwards or to the "ACC" position the radio won't work, the headlights DO work but I don't get the warning chime when I open the door with them on.
The flash-to-pass works, as do the hazards and the turn signals (which seems odd -- I don't recall having a car where the turn signals worked without the car being on). With they key on, everything works including the dome light and the door chime. Is there some simple thing they could have done that would make it work this way and is easily reversed?
2002 Ford F250 V10 Auto... When I put the transmission into reverse, the starter kicks in...
View 8 RepliesI have a 1998 Ford F-150. It has an issue with starting sometimes. The truck won't start with a fully charged battery but when I hook it up to a charger, the truck starts normally. It was going to get the wheels aligned today and when the mechanic went to drive it off the ramp, it wouldn't start. I told him to put a charger on the battery and it started right up. Without the charger it just cranked over and wouldn't start. It doesn't do this every time I go to start it only occasionally. The mechanic had no idea what the problem was and has never heard of this kind of situation. I'm assuming it is an electrical problem but I'm not an expert with engines. The battery was fully charged at the shop and the battery is a year old.
View 4 Replies2001 F-350 diesel. Out of nowhere, I start the truck and there's no turn signals. Fuse is blown so I replace it. It immediately blows. Tail lights work. No turn signal, brake lights, or hazards. I haven't hooked up a trailer or done anything abnormal recently. Only the #1 fuse (20Amp) is blown. Pulled bulbs and they work fine. Inspected wiring under and near lights. NOTHING! Any way to localize a short?
View 2 RepliesSO, my Buick has given the code for bad TPS, and it was replaced a little over a year ago...and now after the same symptoms, replaced again.. However, this time, right after replacing, it gave the code again, and still stalls out /doesn't want to stay running especially when put in gear. My regular mechanic also recently just put on a new catalytic converter and a new fuel pump and fuel filter. I'm at a loss, and desperately need my car back.
A little back history...about 3 years ago a 'friend' was to work on my car to install the thermostat and power washed the engine...which shortly after started having all kinds of electrical issues. Right after that, my mechanic had to install a coil, spark plugs, new ignition panel and the 1st tps.
I am a beginner when it comes to anything involving wiring. I am looking to re-wire all of the wiring coming off of the instrument cluster gauges. Once I have completed all of the wiring on the gauges, I may feel confident to move onto something else. As of rite now, it appears as though my truck is still running on all of the original wiring, and over the past few weeks, I have been having many wiring related issues. I found a schematic that includes the wiring for the gauges that I am going to go off of. I have a couple of questions before I begin.
1.) On the schematic, it shows connectors such as "Connector G" which is moving all of the gauges wires to there locations. Do I need to use a specific Ford connector, or could I purchase a new connector at any hardware store that carries them? As far as I am concerned, connectors do the same thing as all other connectors. (Let you connect and disconnect for easy instrument cluster removal.)
2.) I am not looking to purchase one of those expensive wiring harnesses. I would like to just purchase some wire that I can cut / use myself. What brand / type of wire should I be looking to purchase? I do not care if it is striped / colored as I will use wire tabs to name / label each wire.
Other than that, I feel confident enough to attempt something such as this. Here is the wiring schematic I am going to use.....
Any COMPLETE headlight switch wiring diagram? Everything I find online only shows 2-3 wires in each sub connector, nothing with all wires and colors, and what they do. and of course the factory service manuals no longer work on my new computer. the switch and associated wires went up in smoke 2 hours ago, and this truck is my only means of transportation rite now. what i need is headlight wiring with colors so i can temporary hook up a toggle switch to have lights until the new switch and connectors come in next week. I went to pull the switch and connectors out of the parts truck, but of course that does not have fog lights so it uses different switch and connections.
View 14 RepliesI plan on moving the engine/drivetrain from my 1986 F350 460 to my 1996 F250. I also want to move over the 1986's ignition system with a Duraspark 2 setup.
Although I could just cut in the easiest places to remove the wiring for later reuse I am looking for where to make the cuts, what to take and what to scrap. Alternatively I am also asking if there are aftermarket or OEM replacement sets out there are aren't a ton of money. The current harness in the 1986 has been sprayed with engine oil and cooked for 27 years so I am looking at alternative options if there are any.
I have a 97 F250 HD. Wiring the rear tail lights. When we bought it the had cut off the wires going to both sides of the rear lighting assemblys and I was wondering what wire went to what i have the left turn signal working just can't seem to get the brake/back up light to work on that side and i can't figure out how to get the right side going either.
View 8 RepliesLooking for a source for a wiring diagram for the 2003/4 f350 instrument cluster, specifically the wiring/connectors to the gauges? A link to a PDF file would be nice. I would like to try and disconnect the PCM control to the transmission temperature and engine temperature and drive the gauges from my own sensors to bypass the non-linear behavior that ford decided was in our best interest. I am NOT interested in installing any more gauges, just want to control the ones already present with my own signals. It is possible that these gauges are all addressable devices on a common bus, instead of individual controls.
View 8 RepliesJust bought an 04 Super duty with the factory plug 7pin and 4 pin plug. Checked the fuses and finally tracked down the 2 relays under the hood but can't seem to find anything wrong. Everything on the trailer works except for the running lights. Is there another fuse or something I have missed? Trailer works fine on my buddies Duramax and worked fine on my old 97.
