  1. Electrical & Wiring
    Hey guys, I ran into a seriously odd problem. I have a 1992 gt that I am restoring. When I got the car the headlights didn't work, so followed that to the common problem of the multifunction switch and headlight switch harness being melted from the fog light load. Ordered new harnesses for both...

    I bought my 89 lx hatch as a roller. Originally a 4 cylinder car, have converted it to a 5.0. I have been trying to figure out all the electrical work and this has stumped me. The battery has been relocated to the back. The power side of the starter solenoid gets over 12 volts, but when the...

    Anybody have an idea what might cause this voltage drop? Drops really low when lights are on, but only at idle. As soon as I hit the gas it goes right back up. I thought maybe it was my old negative battery cable, but a new one didn’t fix it. Thanks in advance.
  5. GT & SOHC
    All, I recently bought a 96 Mustang GT, which for all intents and purposes has no issues. The ONLY thing I have found to be wrong with it is some sort of an electrical issue where the doors will rapidly lock/unlock a few times every 5 minutes or so. I haven't done any deep dive into it yet...

    I clamped both of the the soft fuel hoses in the engine bay and the fuel pressure dropped anyway. That led me to suspect a leak or that the fuel injectors are sticking open. I pulled the fuel rail up, making sure to keep the injectors installed. A piece of paper towel under each injector showed...

    I bought the car Monday for real cheap. 2000 3.8L manual. I'm in the middle of home renovations, so I haven't spent much time on it. The PO said it had a dead battery and bad fuel sender. He said it had been sitting for 6 months and hadn't started in 3 months. Judging by how rusted and...

    I have a 1991 4 cylinder lx 5 speed with 5.0 conversion. I recently purchased the vehicle. The dash harness I have is the original 1991 4 cylinder lx. I am trying to figure out what this connector is suppose to connect to. I have the ford repair manual and the electrical&vacuum troubleshooting...

    I have a 92 foxbody. I see quite a few t-56 transmissions out of 03-04 cobras up for grabs but am not sure on how to convert the speedometer. Can anyone give any advice on how to swap the electronic speedo out to make it work with my mechanical one or any possible routes to go about making this...
  10. GT & SOHC
    So I'm having just a little bit of trouble diagnosing what is wrong with my 04 GT. I pulled my motor out and rebuilt it, and also did a battery relocation to the trunk. Everything is back together and I can't get it to start! Before tear down the car worked fine, but now, as soon as I connect...

    I've got a '99 GT that I swapped out the motor (stock for stock). New motor is from an '01 GT. I've made every electrical connection that I can find, but it seems that power is not being supplied to several areas of the car. The engine WILL crank, but does not start. There is zero fuel...
  18. 5.0/5.8 Engine Tech
    I have an '89 5.0 Mustang and for some reason the car turns over with battery connected and no key in ignition. Could this be a starter? Ground problem with wire from Solenoid to starter? I have just replaced the solenoid and still have the same problem. Perhaps the little black relay is bad? If...

    I am looking for a good mechanic in the Los Angeles area that can help me with my 1989 5.0. Several mechanics have told me they are unable to read code ever since I got my engine replaced (stock) and I would like to get it diagnosed - since my check engine light is on as of yesterday...

    So about 2 years ago i posted about this before. Anyhow i've not ran o2 Sensors in that long, and i've been through a few setups now, but i'm back to using a pms and I thought about trying to run o2's again with this new motor to try and improve my poor fuel economy. Anyhow here's the deal. The...
