From this limited discription, there is a short, you need to check the wiring.
Testimonial: "The truck will run for a few days and it's after I shut off the engine it won't start. Is there a common spot the wire is going to ground"
SOURCE: the ECM fuse keeps blowing out
check the wiring to fuel tank something shorting. replace wires to fuel tank.
SOURCE: truck wont start keeps blowing the ecm batt fuse
You have a short (bear wire) somewhere. Trace the wire and find it.
Have a great evening

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...

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.
