Resolved Electrical

[The special Medic]

I have a 1998 mustang V6 and the either the eec fuse or the fuel pump fuse blows after like 30 seconds ( the fuse was misslabled on some modules so idk which)

I have a 1998 mustang V6 and my alternator case is positive,

I don't know what this means.

it is misfiring on one of the cylinder banks,

This sounds like a separate issue.

and it keeps blowing the fuel pump fuse

This also sounds like a separate issue.


Have you pulled codes?

Something like this will get you there: https://www.amazon.com/ZM201-Profes...nced-Vehicles/dp/B0C2V3RYLY/ref=sr_1_9?sr=8-9

When the ground cable was hooked up to the casing of the alternator it acted like it caused a short, and at the moment there is not a check engine light

You still need to pull codes. The trouble light doesn't illuminate for all codes.


Do you have the means to remove the alternator and have it tested at a nearby auto-parts store?

On a parallel note: What kind of shape is the battery in?

I'll leave this here too. I'm certain we have one for this section but I can't find it>

I should be able to, and the battery is recently new and in good shay

I know my Autozone lets you borrow an ODB-1 tester, maybe try that?

I have a V6 1998 mustang and my fuel pump fuse keeps blowing where do I start?

 

[The special Medic]

Ok so atm the only thing it's doing is blowing the fuel pump fuse (1998 so the fuse may be mislabeled)

Sounds like you have a short somewhere. Do you have access to some wiring diagrams? You are gonna need to do some digging

 

[The special Medic]

I found some diagrams and apparently the fuel pump fuse and the eec fuse were mislabeled so I'm gonna start by checking the O2 sensors

 

[89ripper]

So you are saying you were blowing the eec fuse?

Hi, does the fuse blow instantly when you turn the key on? Does the fuse last for a while? a few starts, a few days, a week or more? Do you live where rodents are an issue under the hood, eating wiring and such? Is the fuse socket in the box corroded? Was the first fuse that blew, corroded? Do you have an electrical meter? Have you run out of gas in the last 6 mos. to a year? Do you know how old the pump is? I know that's a lot of questions but you can start at the connector to the pump at the back of the car look for power & ground, if the fuse will hold long enough. I know there are others on the forum with better answers than mine but I thought I'd give it a go here.

@The special Medic - I've merged your 2 threads since they were both the same basic topic and both had the same title.

It pops after about 30 seconds
Fuel pump is new

I think, it's one of the 2 because I've seen some say it was mislabeled but it's marked as the fuel pump fuse in the manual so idk

Hey, sorry I did not see your reply. Did you get it fixed?

No I haven't had the chance to look at it till now

Thanks for the help, as of Thanksgiving week I was able to solve the issue, a wire running to the coil pack was frayed and was shorting to the hood
