John, Here are some corrections concerning your statements. John said: "All the relay's in the De Lorean are resistive load and are prone to fail". DMC Joe: The DeLorean relay's are not prone to fail. The early version RPM relay and factory installed door lock relays are the only relays with a higher than average failure rate. John: "Moisture and underrated contacts is why a lot of fuel pumps fail". DMC Joe: DeLorean fuel pump failures are the result of dirt, rust, or contaminated fuel; not electric's. John: "The fuel pumb burning up the, I think #7 fuse, I have that fixed also." DMC Joe: The fuse #7 failures are strictly related to an under rated fuse holder, this common problem is easily corrected with the installation of a heavy duty in-line fuse holder, not a circuit modification. John: "But it seems that a lot of De Lorean owners have only seen one way to approach problems with the cars and have been kept in the dark. I think I have opened a lot of eyes ..." DMC Joe: Not so; the DML offers a variety of solutions for most problems, just check the archives.
