so mustang wont get any power (electrical). its not the battery, its not the alternator. its not the starter solenoid. anyone have any ideas? this is so frustrating=/

Bad ground maybe....

How do you know that the battery, alternalor, ect.....did you have them tested ?

[Cody90GT]

yea. had them all tested. replaced my starter solenoid. took the battery out of my 93 f150 5.0 and threw it in the car and it didnt work. and the alternator is brand new and i had it tested. which ground should i check?

[Stdyhand]

I had the same problem with another car and it turned out to be a bad ground. Start at the battery and remove and clean all grounds as you trace them out. It's time consuming but you might get lucky and find it rather quickly.

[Cody90GT]

i hope so. guess thats what my whole sunday will be consumed by. good thing i have the day off of work. ugh.

[Stdyhand]

It's not too bad really. Thats what I love about Fox mustangs, most things are fairly easy to fix. It has decent room in the engine compartment considering how small the car is and it having a 302. Trying to work around a 350 in a mid 90's camaro is a pain.

[cleangtvert]

replace the ground.

[tater302]

just had the same problem with my 91 coupe i'm building. I replaced battery, alt, and starter nothing helped then found out it was the main ground coming off the solenoid mine was bolted to the engine to get ground. The bolt was just finger tight...i put a wrench on it and the car fired right up! small things like that can get on your nerves. But building cars isn't suppose to be easy.

had a 85 3/4 ton did the same thing to me. truck was down for two weeks before i figured out the ground was bad. if you get nothing. its usually the ground.

[Cody90GT]

thank you. im going to go out and try that and all the grounds. hopefully thats all it is!

[rjay]

Had that problem once, there's a module, or pick-up unit , forgot what you call it under the distribtor cap went out.

[Cody90GT]

i literally just came in from replacing that module. that didnt work either. i replaced my ignition cylinder, that didnt work. cleaned all the grounds and tightened them down and that didnt work. im at a loss for words. this really is ridiculous. its killing me. should i replace the computer maybe?

Be more specific on what your issues are. Saying no power made it sound like you have a rotten battery cable or something. Are you just meaning that you turn the key to the start position, that nothing happens. Be specific.

[recore]

Sounds like you may have already done this, but just in case I'll throw it out there. Make sure the battery terminals and connectors are clean. I've had the problem a few times where I lose all power and that has been the cause. Good luck.

[Cody90GT]

ya i put it to the start position and i get nothing at all.

I can't believe this thread went 13 posts before someone asked this.

Still going to have to be more specific than when you turn to start nothing happens. What about when you turn the key to ignition on? Do you get ignition power or is it completely dead in that position too? You need to specify what is happening so people know what circuit isn't working and can help to narrow down the possibilities.

[Cody90GT]

i can turn the key to any position and i get no power. accessory gets none. ignition on gets no power. there is no power at all

[fogged306]

Then you need to go back to the solenoid on the fender and check for power on both sides of the big terminals. Use a multi-meter or a 12v testlight.

[FastStang91Lx]

Check power going into your fuseblock also. Follow all the wires going from the line side of your solenoid. Starter wire would be your load side. There should be like 2 or 3 wires hooked under the same nut as the battery wire. Follow those wires and keep probing.

might also be the plug by the key. If yours have never been chance since 91 i guarantee that shits done.
