Ford F-150 - Recent Questions, Troubleshooting & Support - Page 5

I'm sorry to hear you have this trouble. You don't say whether this is manual or standard so it is hard to say much more.

I don't think you can fix this in your driveway. Probably the transmission has to come out. See your mechanic soon, in the mean time, be careful how you park.

in the engine compartment fuse panel
remove the 50amp maxi fuse in location #102
(look on the back of the cover to find #102)
and that will disable your ABS

Engine oil could be valve cover, transmission fluid could be coming from the filler tube, coolant could be a heater hose.

Go to AutoZone and borrow the long bar that fits into the tensioner pulley.

They are on the harmonic balancer but can be dirty and hard to see. Was the balancer edge really well all around and you should find them

Try your boo(brake on/off switch) switch on brake pedal. unplug it and jump connector with a piece of wire and have someone look behind truck and see if brake lights turn on. if brake light illum,there you go replace switch. make sure pay special attn how switch comes off after pulling pin out. also try fuse if all else is ok.

Crank and or cam sensor is starting to fail. When the proper signals from these sensors are interrupted, the engine computer does into a limp in mode so you're not stranded in traffic. Have a code reader connected to the diagnostic port and see what the codes say.

There is an alternative idea here. https://www.f150online.com/forums/pre-1997-models/475590-negative-ground-battery-cable.html More ideas and videos https://www.google.com/search?q=1990+ford+f-150+replace+battery+ground+cable ..

Question edited for clarity, written English and FULL 'year maker model. Question moved to model category. Duplicate post deleted. Refresh page to see your question. It could be dozens of things, but start with checking fuel pump, fuel pump relay and fuel pressure. It can't be the ECU because it runs when you add fuel. Engines only need three things.

1. Fuel
2. Compression. You have because it runs.
3. A Spark at the right time, You have because it runs.

It runs when you are fuel manually, so fuel delivery is your issue. Does it have an alarm and immobilizer? Battery disconnected or ran flat recently?

Question edited for clarity. Question moved to correct year make model category. You are using what I call the "let's try changing this" method of auto repair and as you have found out it is expensive and doesn't work. Your vehicle is run by sensors, modules, the BCM and ECM all connected and working on a computer network. The only way is to get the services of an auto electrician who will connect a $5,000 pro grade scan tool computer and diagnose every system and module in the vehicle. One benefit is that they can record everything that is happening, when all these odd things are happening in real time. Then they can even play back the details and work out what the issue is. https://www.google.com/search?q=auto+electrician+near+me ..

This sounds like the brake light switch or the control switch on the brake pedal is bad or loose. Check under the dash above the brake pedal there should be one or two switches that tell the brake lights to come on and the cruise control to shut down.

First step is to change the fuel filter and test the car. If the problem still occurs: The fuel pump driver module was corroded through from salt and was malfunctioning. Bought a new one and runs great. Problem fixed. See pictures below:


This is why salt destroys cars.

the a/c clutch relay is located in the power ditribution box under the hood. check relay #204 as per the legend on the underside of the lid of the box

I'm going to assume that your talking about the fuse box inside the vehicle and not the one in the engine compartment (the power distribution box). This should be in your owners manual if you have one. If you need a copy of your owners manual just email me at [email protected] with your make model and year and I will be happy to email you a copy. Don't worry it's free. I hope this helps and good luck. If you need the ones for the engine compartment box just reply to this and I should be notified that you did or you can just email me. Heres your pictures:

P1260 = Theft Detected - Engine Disabled

This OBD Code indicates that the Passive Anti Theft system (PATS) detected a "theft condition". This basically means an incorrect signal, or no signal at all was received from the chipped key. Brief overview: your ignition key has a chip in it called a transponder that is read by the PATS transceiver (mounted around the ignition cylinder housing behind the column shroud). The signal is then sent to the PATS control module, which communicates with the Powertrain Control Module (PCM) and enables the vehicle to start.

When an incorrect signal is received, the PATS module then sends this message to the PCM which triggers the P1260 trouble code, resulting in a no start condition. Possible causes are: an incorrect key being used, faulty key chip (transponder), wiring concerns between the transceiver module and PATS module, the transceiver module itself or internal PATS or PCM module concerns. The first thing to do in this instance is retrieve codes from the PATS module and diagnose these. Once the PATS issues have been resolved you can reset the P1260.

Communication with the PATS module will likely need to be done at a Ford dealer. A few things to check first: make sure the correct key is being used, and if you have a second key, try that one as well. If one key starts it but not the other, you may have a faulty key. If both keys do not work, then it is not likely a key problem. Honestly, we see very few problems with the keys themselves. Make sure no one has tampered with the steering column shroud as the transceiver module located behind it is fairly fragile. Lastly check for an aftermarket remote start system. These are a common cause of no start problems with PATS equipped vehicles. Some installers will remove the chip from your key and tape it to the column (under the shroud). This basically bypasses the system and allows it to be started without a chipped key. The problem is that the transponder removed from the key is not designed to be used in this way and can fail due to extreme temperature changes and, depending on mounting condition, excessive vibration and shock. Other installers use a "key box" installed under the dash, and these have been known to cause issues as well. If you suspect the concern to be related to a remote start it may not be a bad idea to have it checked or removed to complete diagnosis.

Also, its possible that you are interesting in check the Ford F-150 - Owners Manual (page 94)
