Question about Cars & Trucks
2010 cobalt blowing eco/trans fuse.
Found problem. It was a wire that was rubbing against the top metal part on the oil filter housing. The wire sleeve aka wire loom is bad about deteriorating. Then the wire rubs a hole through the insulation and causes a short. All Cobalt owners need to check the wire sleeveing,conduit, loom, what ever you happen to call it. Hope this helps. P.S. if wire breaks into. It also causes oil light and the transmission will not shift out of low gear. It will give a trans code. 1/2 and 2/3 solenoid bad.

SOURCE: ecm fuse keeps blowing
just fixed this problem, change your fuel pump module, fuel sending unit shorts out on fuel level swing arm blue wire... unfortinately you must replace it as unit because of the design, fuel pump and tank guage fuel level sending unit are a one peice item, fuel tank has to come out to change unit, about a $ 700.00 repair too... fuel pump module runs about 350 to 700 $ depending on aftermarket or factory, try to find one with a lifetime warranty even if it is $ 50.00 more worth it..labor is about $ 250 to $ 400 depending on shop labor rate... definate problem though I ahve no doubt, common problem on GM... please rate my help, thanks...

SOURCE: the ecm fuse
Hi, this could be caused by a short circuit in the ECM or it more commonly found a short circuit in the alternator. Disconnect the battery wire from the alternator, make sure that the wire does not touch any part of the body or engine. Replace the fuse and see if it still blows the fuse. If the problem is solved, replace the alternator, if nor you will need to test the wires for a short circuit.

if it is the ecm b fuse thats blowing i would try disconnecting your oil sending unit and see if it still blows the fuse.i have seen the sending unit short out internally before and blow the fuse.if it is the ecm 1 fuse it is either a chaffed wire or one of your injectors shorted.

If it "keeps" blowing the ECM fuse, it is because you "KEEP" replacing the fuse without diagnosing and repairing the reason the fuse is blown.
