ok so my 91 limited broke down i though it was the fuel pump replaced it and fuel filter then did a full tune that didnt help then i was on here and found out that it was the crank shaft sensor so i changed that and it fired up then died did it a second time and it blew 30 amp engine contol fuse in the fuse block under the hood i put a new fuse in it start it dies do it again it blows the fuse i did this 3 times and i dont understand why it keeps doin this its really pissing me off any ideas why

Maybe a short circuit somewhere?

That`s a pretty complex situation with all the things that have been worked on. With the fuse blowing in there I am thinking maybe something happened to a wire and it's grounded out somewhere and blows the fuse once whatever is shorted tries to send a signal. But that's just a wild guess.

LOL. We sent our posts with the same idea at the exact same moment.

I agree with the above statement of a wire grounded out somewhere. Make sure you didnt nic a wire while you were doing the fuel pump or something is not cross wired.

fuel pump only one way so it maybe a possiblity that a wire mite of got a nic in the wire i did pull the main plug back thru the hole under the back see i guess ill have to check it out and let u guys know
