My S1o died on me the other day at first thoiught it was the fuel pump bet it keeeps blowing its ECMB fuse. We unhooked the fuel pump and put a new fuse in and as soon as the battery cable made connection it blew the fuse. any ideas?

Check the wiring for the fuel pump prime connector and the auxiliary oil pressure switch. If those are not grounded, the only other thing in the circuit is the ECM.
