2008 IC CE Maxforce 7. The ECM fuse blows that is in the battery box. Unhooked the ECM relay under the hood turned the key and it does not blow the fuse hook it back up and blows again. The wires go down to the loom going into the ECM do think the ECM has a short in it or has anyone have any other ideas.
Thanks |

| Check all the wiring from the ECM, the relay, and the battery box. Replace the ECM relay. If all those fail, then you may have a shorted ECM, very doubtful. |
If you can't handle the answer, don't ask the question |

| Checked all of the wiring from the fuse to the ECM could not find any shorts. Removed and replaced ECM relay it still shorted out. Sent the bus to our local Dealer. They found the fuel pump was shorting out and was the problem. They removed and replaced the fuel pump under warranty and all is good. |
