First off, Thanks to all those who have knowingly and unknowingly helped me with this project! Many searches through the forum archives have answered many questions for me. Here's a problem I couldn't find an answer to. I installed a new 350 ram-jet in my 73 blazer. Upgraded the alternator, added electrial fan, updated single pole starter, wiring harness for EFI ,and replaced old damaged wires in engine compartment. The engine will turn over but no spark at the plugs, unless I run a wire from the battery to the fuse box ( I'm attaching it to the same fuse as the air pump and the EFI wiring harness). Then, the engine will start and run well. To stop the engine I need to remove the wire or it won't stop running even with the key off. If I leave that wire connected to the fuse box, the fuse box remains "hot" with some accessories left on. Is this a wiring problem between the key and the fuse box or between the battery and the fuse box? I'm not very good with electrial. Clearly, I've miss wired something or removed a neccessary wire. Again, thanks for the help. Shouts to Dontoe, and Poohbair. PICs of the progect are on my website.
