    1986 5.0 Efi Issue

    There's nothing to do until we have your fuel pressure and volume test results. Also, if you can access your fuel pressure regulator, pull the vacuum hose off and see if there is any fuel present at the vacuum port that would indicate a blown diaphragm. Check the engine coolant sensor connector...

    Steering Play

    Unless you are going to hang big power, big wheels and big brakes on it I would just stay stock.

    Turbo Newbie - 79 Capri

    Disable spark and fuel, hook up a battery charger and crank it through in 20 second bursts with a 30 second pause in between to pre-lube the engine and turbo before attempting to fire it up. Other than that, the normal rules for waking a car from the dead apply. You'll probably end up having to...

    Please Help Ac Compressor Will Not Engage

    Possible AC clutch relay fault in the CCRM. This is the relay module that contains the relays for fuel pump, cooling fans, ac clutch, etc. Usually mounted in the right hand fender. You'll have to remove the air cleaner assembly to access. I have replaced many of these for ac clutch inop.

    Engine Swap

    That sensor on the rail actually is the fuel rail pressure sensor and is used on non-return systems. The PCM references it to control fuel pump output. You will need the correct harness for '99 and up along with the correct PCM. It's a little more hassle than it's worth to convert to a return...

    Dome Light Problems Need Help

    Well, in normal operation, the dome light should go out as soon as you close the door if the key is on or engine running. So your symptom means that somebody with a decent scanner that can talk to the car's Generic Electronic Module (Body Control Module in Ford speak) will have to investigate...

    Crank, No Start

    Well, did you take a magnifying glass and a good light and inspect the injector inlets? Were the micro-screens clean? I have on occasion set myself up a battery with an old injector connector, had the injectors/rail pulled up with rags under them blocking the injector ports (don't want to get a...

    4.6l Rough Idle And Flooding

    My first suspicion is the fuel rail pressure sensor is leaking. Pull the vacuum line from it, if you see gas replace it ... NOW. If you don't see gas come out of the vacuum port, then you will need a scanner to check the rail pressure sensor value. The system should set a code if it is out of...

    Electrical Power Windows

    How is the window speed when going up relative to the other window? If it is slower the cause could be wear in the felt channel guides. Modern motors use a current limiting biscuit style resistor in the motor. If there is any appreciable drag on the window it acts sort of like a circuit...

    Alignment Fix

    Since the spring on upper arm system uses shims for alignment, and unless you are losing the shims while driving, I am at a loss to understand your vehicle "not holding" it's alignment. What condition are the springs in? Has ride height been measured against spec'? Do you have any excess play in...

    Engine Engine Revving On Its Own (burning Out My Clutch!)

    Would need to confirm engine temp sensor input, but along with your hard hot crank complaint I'm thinking you should start with verifying your battery power and ground connections especially at the starter and engine. Also the ground from the negative to the body as well as the ground strap from...

    Need Help With A Fuel System

    When you set up your system, make sure the pump mounting is at or slightly below the sump level. Also, do yourself a favor and put an inline fuel shutoff valve on the sump outlet to allow for filter and pump maintenance without having to drain or lose your fuel. You will need to replace the...

    Led Woes

    Problem resolved. It was faulty bulbs, the supplier sent new ones that worked properly. Apparently there was a bad production run. Yitamotor did right by me.

    What And Where Does This Go?

    Purge solenoid. Often times found hanging out near the purge canister or intake.

    Power Window Problems

    Inspect the harness in the conduit between the cowl and door. Over time internal wire breaks happen in this location, especially with lots of door cycles. Kinda like when you bend a paper clip back and forth enough times, the metal fatigues and then breaks.

    Led Woes

    I have run into an interesting problem on my buddy's '94. We wanted to put LED bulbs in the car, so we started with the rears. After installation of the bulbs, we had stop/turn but no park/tail. Confirmed polarity by reversing the bulbs in the socket, they would not work at all that way. The...
