It turns over, but why won't it start?

Did you check for spark ? Are the fuel injectors firing ? Does the check engine light come on when you turn the key to the on position , an then go out when you crank the engine over ? No Start Diagnostic Basics EricTheCarGuy

Where can I get a diagram of the intake manifold runner control?

Do a Web search under the terms (Your make, model, year vehicle) intake manifold runner. Or intake runner control solenoids, rods, etc. You may find Youtube videos. The runners are sandwiched under or inside the intake manifold. Some had plastic clips which crumbled and the operating rods became disconnected. Some runners stuck too bad for the rods to move them.

Why when the key is off Only one potion of the brake light on the trunk stays on on my mustang. all the other are off

That car has a lot of lights for a stop light. Maybe they require more than one fuse and/or relay. Hope this helps.

I have a 2003 ford mustang gt wipers stopped working replaced relay and fuse and still nothing is there something i am missing. I was told that it was the connestion under the right front fender but i

try tapping the wiper motor, with it turned on, with a hammer if it starts the motor is worn and needs replacing. you can try attaching a separate ground wire to the wiper motor if it runs then the motor has lost its ground and you can run it this way.

What would cause my 03 4.6 mustang To not take fuel but it will idle

You may need to change your fuel filter. It could be dirty enough to not let enough fuel pass through. Could also be a weak fuel pump. I'm not sure if your vehicle has one but your throttle position sensor could be bad. I would try fuel filter first. Take it off and let it drain and watch to see what color the fuel is when it comes out. If it's anything other than clear I would replace it. Hope this helps.

I have a 2003 Mustang that the wipers stopped working on. I have replaced the motor, switch, relay's and checked all wiring and fuses and I still have no wipers and I am unable to find the rig

You may have a bad wire or it could be in your wiper switch on your steering column. Have you tested to see if you are getting power at the motor?

I am wondering if the dealer screwed up when they flashed my computer or if I just bought a bad computer (autozone). Or if it is a problem that I can fix myself.

Never take your car to a dealer even if your life depends on it , they charge you to much money for anything and when they mess something up the will charge you to fix their mistake should ha got ton one on eBay the reset themselves when plugged in but they will not tell you that as long as it is from the same car

2003 Mustang V6 Basic I installed model

Hello . I have done some checking on this . The kit should have come with instructions . You might try to look up the manufacturer online and see if they have the wire diagram you will need to make it a little more easy . If you go to youtube and input under video search " Mirrors presented by Andy's Auto Sport " a video will come up that will show you basically what you need to do . Since your car was not equipped with turn signals in the mirrors you will have to run the wireing under the dash to just below your steering column . There you will have to find what wire runs the left turn and what wire runs the right turn and splice into them with the mirror that matches . Your mirror should have a power for light which will connect under dash and a ground which you will ground to the metal body of your car under the dash ( look for a bolt or nut that you could connect this to ) . I hope this is helpful to you .
