electrical issue

Manual 2003 GT 4.6L coupe that will not start. What else should I do to troubleshoot the issue? What seems to be the most likely culprit? Who's had this issue before and was able to resolve it / how? PROBLEM: Key goes in, theft light turns off after 3 seconds, keys turns to start the engine -...

I've finally got my car to start, idle, and apparently only drive in reverse. My 2002 GT Convertible is having some issues. The car starts, idles, revs, and reverses like a normal car should. It has no CEL, alternator is new and tests good, but for some reason when you put it in first gear and...

Hi all, 1994 V6 Mustang, bone stock electronics. I was driving and the car completely shut off. On the side of the road I had a crank no start. After a tow home I see fuse E in the engine bay is blown and has continued to blow as soon as key is switched on. It controls - PCM - Fuel Pump - O2...

Okayyy so my ignition switch in my foxbody 91 disassembled like it seperated from the metal part so i tried to put it back together while car was connected to battery while i was doing that in a moment i heard a pop and white smoke came from under the hood driver side. Inside the car nothing...

I have a 2003 GT Convertible and randomly it blows 3 fused all at once. I can't pinpoint the situation when it blows. It seems totally random during driving. I try and replicate it in my garage by hitting the brakes, using the turn signals. Holding the brakes, and hitting the turn signals etc...

So...I drove my 90 GT the other evening as I often do. Didn't notice anything unusual while driving it but then again, I only drove it a half mile. Brought it home and parked in the garage. Next morning I went to use it and the battery was almost dead. Wouldn't start. Every once in a while...

2002 Mustang GT Auto. Previous owner added a Dei 530T Module so the wiring is not orm from factory. I fixed the driver side power window and lock by re wiring everything back to stock. My problem is my passenger side is getting no power at all. Side Mirror and window do not work with any of the...

So I was performing maintenance on my 99 v6 3.8 this past weekend, I replaced the valve cover seals and lower and upper intake manifold gaskets. Reassembled the engine completely and started it up. Car ran for approximately 15-20 while I was bleeding the coolant system. I loosened the upper...

I noticed my tps and other sensors like iac and others are giving a 12 volts read on my multimeter with key-on instead of the usual 5 volts it goes as high as 18.5 volts with car on! I'm guessing those ("missing") 5 volts show up eventually when I turn the car on? But wait , how can that be... I...

First post here. I’ll get straight to business. I have a 1988 5.0 Im currently restoring and the tach is dead. I have removed the whole harness during the resto and gone through it from the ecu to the engine. The tach only moves when cranking the engine to about 100-200 rpm. I have tested the...

Alright, I have been lurking here for awhile as my vehicle has given me nearly non stop issues thanks to the previous owner. Finally I have an issue that I cant find a solution for in the forums, so here i am. A couple weeks ago I went to the store and upon trying to leave, I was met with a...

Ok so for about a week now I've been getting this odd electrical issue with my 90 GT only when it's raining (I live in Seattle so pretty much everyday that ends with Y). It started last Friday when I was heading home from work, the radio will cut out for about half a second and the wipers will...

I checked all over this sit and have found nobody else with this issue. My pretty purple pony is possessed! Last week my drivers window rolled itself down on its own while I was warming up the car. I tried pressing the button to roll it up with no result. As I drove I tried the button again and...

Ok guys im going to try and explain this as best as I can my 1993 mustang gt is acting crazy!! So for the past week or so ive had a few electrical issues nothing I was to worried about. A few examples are my dome light went out. My headlights flashed once and about a month ago my headlights went...

I have a couple issues going on with my Mach 1 at the moment. For one i recently replaced my drivers side window motor since it went out but now when ever I raise it all the way up or drop it all the way down the motor doesn't stop and make a loud clicking sound of the 2 gears clashing unless I...

I am absolutely confused and infuriated with this problem. I have not seen any other threads that describe an issue anything similar to this, so here goes. For the past few days, my car has been starting perfectly fine every time. It has no hesitation starting, and it seemed to run quite well...

I've acquired a 99 GT (4.6L w/ 4R70W). It's got 120,000 miles on it. It had a lot of electrical gremlins under the hood. I've re-wired just about everything under the hood. New elec plugs, new alternator, new coils, new starter, re-did all grounding connections, etc. Front end electrical seems...

Hey guys I’m new to the forum, just bought a 86 GT hatchback and the passenger window goes up and down fine when you use the switch on the drivers door, but if you try to roll it up or down with the switch on the passenger door It doesn’t do anything and it shuts off the radio, when you let go...

I just bought a 2003 mustang gt three weeks ago and I have been chasing an electrical gremlin. the person before had spliced in a custom alarm system and I found the tail light fuse was blown. some of the things that I have noticed is when the car warms up the battery light comes on. had the...

Just picked up a 98 GT , the problem is it will start , the run for 10 minutes then shuts down and will not restart for at least an hour. My code reader tells me "theft detected engine shut down? The theft light does not blink or stay on. It comes on when I turn the key then goes off when I...
