starting woes
 

Start the motor in sig up. runs and drives fine. water temp is 180-190. New 92 mustang starter(high torque). But after running and shutting off, it wont crank over but just a little bit. Battery/Alternator is good.
It will cool down and start up later. Long tube headers. Didnt have this before with these headers, but I did put exhaust wrap over the headers to try to lower under hood temp. Now it wont crank after running.

Check the positive wire from your selenoid to the starter.
I bet it's either loose or the wire is getting too hot from the headers.
I had the same problem with my shorty headers and I moved the hot wire away from the exhaust pipes and that solved it.
