MY truck stopped running yesterday and the ECM1 15 AMP fuse was blown. I replaced it and the truck started and ran for about two minutes and shut off again. The fuse was blown again. I tried one more fuse and it blew the minute I turned the igniton on. Any Ideas of what is causing this?

Unplug the voltage to for ignition module, see if fuse still blows? pink wire. May not be conclusive, the other leg from the fuse goes to the pcm. Can't tell about the pcm? If it points in that direction, something may be affecting the pcm.

There might just be short in the wiring circuit, somewhere, to the ignition module or pcm.
