Blowing 30A engine fuse

[Casper123]

ok i am blowing my engie fuse. i was driving down the highway when vehicle just died. after 20 mins i found that it was the fuse. it has blown 3 more fuses and is only blowing them when i am cranking the engine over. i can leave key in on position, but soon as i turn the engine over it blows the fuse. as a side note, it blew 2 fuses back to back, then i had vehicle towed. upon replacing fuse 3 hours later, vehicle started right up and ran for 2 mins. shut off and tried to start up 5 mins later and blew the darn fuse again. i sid do a search before i posted and everything else were people that were blowing fuses after driving them for a while. any help is much appreciated. ty very much

Fuses are meant to protect the electrical system, if you keep blowing fuses, it's trying to tell you something is wrong.

There is more then likely a short somewhere in your wiring harness, causing it to pop fuses.

Look over anything, you WILL find the problem.

Best of luck.

I would start looking at the ignition system if you're blowing fuses on cranking.

just follow Lofty's advice. This is NOT fun at all. You will have to find where that short is. A friend of mine had this problem. Hopefully the problem is more obvious than it was for us.. we had to strip a lot of stuff.

my mechanic sgould be over at my house any min and then we are going to start looking for the short. we are going to start looking at the ignition system including the starter. thanks all for the hel and i will let u know how it goes.

I had this same exact problem and it was driving me crazy. I replaced the fuse over 16 times. Then patiently looking for some kind of short going on, I found bare wire touching right down in the intake manifold.

Masked up the bare wire with electric tape and problem solved.

So my advice is to give a really good check on all your wiring on your engine bay.

ok...it looks like the problem is the cam position sensor. it is not blowing fuses anymore(didnt really do anything but unplug and replug diffrent items in) but it wasnt running cause it wasnt putting out any spark. grounded out the cps and poof, car starts and runs with no blown fuses. sems like cps is going bad, so replacing it to see how it goes.

I was doing the same thing once and it turn out that the bolt head of the fuse box rubbed one of the wires down to the metal and it shorted out. Hope it's a easy find cause sometimes it can be a pain

finally found the problem. when i had someone change out my tranny they didnt bolt up the wire harness so it was sitting on a exhaust tube and melted. it was the coil wires and cam position sensor. ow i gotta get ahold of dude that did the work on tranny and either get my money back or file a lawsuit against
