your over drive relay

If it is balanced it will only go on one way. The bolt holes will be off set.

Could be your thermostat is getting stuck open.

hope this helps

Master cylinder may be bad or most likley air in the lines---bleed the brakes.

Are you sure you have all wires on Starter and Alt, Have you checked fuses for fuel pump, check starter relay, Reason for changing Starter and Alt??? DID YOU DISCONNECT BATTERY BEFORE YOU STARTED REPLACING PARTS???

There no reason why the bigger alternator drive the gauge crazy in that case the bigger the better you can drive more electric conponent

Will not pass or fail?? That doesn't really make sense.

Flooded. Open the throttle all the way to start. You may need to replace spark plugs. And hitting the tank to get started isn't a good sign either. Your pump is about to go.

Ok I'm reaching here have you checked for a blown fuse---another thought is go to advance auto or similar place and have them plug in analyzer to check for codes---I was informed by somebody one time that had problems with radio and vehicle that it was part of the ECM computer----there was issues with the vehicle and do to the radio malfuntioning was causing some of his problems and viseversa---now I don't know if this is your problem but your cd is connected to your radio and it wouldn't hurt to check things out since the code check is free----In addition have you or anybody been under the dash or done anything to the wiring on the vehicle as this may cause an issue---another thing do you have any kiddypoos that might have been sticking things in the CD while nobody was around---that's all I can think of at the moment---good luck

Something has let loose in the transfer case. Probably bearings. Better get another or have that one fixed. Keep driving it and the case will blow a part. This could damage the transmission also.

Could be a fuel pressure regulator not working. Thus ecu complaining about fuel Pressure. probably not enough because the regulator is worn and leaking down so will not maintain the proper pressure. You will need to google the make model and fuel pressure regulator to find it's location or library and repair manual. Otherwise, you need to measure the pressure and find the spec for the required fuel pressure. Probably somewhere around 120PSI

Idle air control valve or mass air flow sensor is causing the issue I’m happy to assist further over the phone at https://www.6ya.com/expert/jeremy_677dced97ad9bddf

if you look under the hood, there should be a label with the picture of the belt diagram should be toward the driver's side either on the crossmember by radiator, or on the hood itself!

First, check all fuses to make sure that none are blown.

If the door lock switch works on the passenger side, then the drivers side door lock switch is probably faulty. Use a multi-meter to test the Drivers Side Door Lock Switch (Black and Pink/Light Green wires unlock the vehicle, and the Black and Pink/Yellow wires lock the vehicle)
If the switch is tested and found to be operating properly, you may have a faulty Body Security Module or Drivers Side Door Lock Actuator.

If neither of your Power Mirrors are working, you probably have a faulty Exterior Rear View Mirror Switch, Power Mirror Module, or blown Central Junction Box Fuse.

If none of your Power Windows are working, you probably have a faulty Accessory Delay Relay or a blown fuse in your Central Junction Box or a faulty Master Window Adjust Switch (all of the Power Window Switches feed through this Master Window Switch). If the Power Windows didn't stop working at the same time, you may have faulty Window Adjust Switches, or faulty Power Window Motors, this is very unlikely though. It would also be a good idea to inspect the wiring for any obvious damage. I’m happy to help further over the phone at https://www.6ya.com/expert/jeremy_69f3cc28d95bf514

There is a procedure in owners manual to turn pass airbag on & off. Also make sure nothing is in seat. Certain light weights will turn it off

Hi, Have you checked ALL connectors for tightness.They have a habit of working loose after a time with the motion of the car,especially a truck. The push in ones being the obvious ones to check first,the earth next both ends. Even the ariel could be loose underneath, if you have that type. Failing any of the above re-make connections and see how you go.You may have loose connectors in side radio,or dry joints. LUCK

I had almost the identical problem on my 2005 F150 FX4 Extended cab last weekend. The power door locks would not lock using the keypad, remotes, or door buttons. Almost all other functions worked correctly. The doors unlocked, the radio delay functioned, and the interior lights dimmed. When I used the remote the horn would beep twice indicating that a door was open even there was no message on the message center that a door was open. When I used the keypad or remote, I could hear a soft click from behind the seat. I think it was coming from the body security module or body security module - whatever Ford is calling it this year. I pulled the fuse for the Power Door Locks(BSM). As I removed it, I heard a soft click - sort of like a relay resetting. It may have come from the VSM/BSM. It may have possibly been a stuck actuator releasing. I don't think so. It wasn't that load. In any case, everything is functioning correctly now.
