I have a 71 Nova with a 434 SB. I just installed a new Griffen radiator and a Black Majic fan. I also have a new 110 alt and an MSD ignition. The car started and ran fine, the fan kicked in and then the car stalled. Now it wont start, but the fan will run. The car cranks but wont start. Any ideas on where to start? Thx

Start with the basics first air, fuel, and spark maybe you loosed a wire during the installation or you burnt a fuse. How did you wire the fan to the electrical system.

I just duplicated the wiring from the last fan. This fan is larger, however. It is not fuel, my pressure is fine.

This is a long shot, but check the fuseable link.

Is the fan wired through a relay? Where is the power being tapped from for the relay?

The link to the fan? The fan works great. I found the key power and batt power from the harness coming from the fuse box. (newer harness). The fan has a new relay..

Where does the fan relay get its power?

A lot of alternator and starter leads have fusible links. They are typically located near the terminal posts on the starter/alternator. You can test them by checking continuity. If there is none, then there's your problem.
