i have a 86 mustang gt with a engine out of a 93 it recently had a new computer put in it and it ran fine for a month and then it started to do the same thing were it wont start and the fuel pump stays trying to prime but before it died it slowly started to run worse and worse

 

also its an automatic aode

 

I would check the tfi module on the side of the distributor.
can cause the issue's your having

 

is there a way to test it with my multimeter???

 

It's toast. You might as well give the carcass to me, I could use some 4 eyed parts.

Are you running any kind of a chip or tuner like a Tweecer on it? If the tune on that gets corrupted or the wrong strategy is used it can cause the pump to run continuously. When you say it won't start, do you mean it won't crank or it will crank but won't fire?

 

AODE?

 

You should switch it to carb. It'll run great then.

Distributor module may be bad. Only way I know (and the fastest) is to replace it with a known good one.

My vote is on the fuel pump though....Or the filter.

 

Dammit, Tim! I was just about to come in here saying that!

 

no chip or program stock computer fuel pump and filter are brand new and aode is the trans idk man this is my friends car if it was my chevy it would not b giving me these problems

 

The reason for NA306Stang asking about the trans, is that year of Mustang didn't COME with an AODE, and it doesn't have the computer to RUN an AODE. Trust me, he KNOWS an AODE is a transmission. LOL He's just mystified (as am I) as to what the heck it would be doing in such an old vehicle. I think the AODE first made an appearance in the Mustang in 1989 or possibly 1990. But I could be off by a year or two.

Did you try replacing the distributor module?



Oh, and you're right, if it were your chevy, it wouldn't be giving you these problems. It would be giving you far WORSE problems.
