Hey all. I recently acquired an s13 with an sr20 and the wiring is a mess. Beyond that, it started everytime, but cranking was always crazy slow.
I was thinking the reason why the cranking was slow was because the relocated battery had a positive lead from battery to a 200amp fuse before going into the engine bay and splitting off on a power distribution block. I removed the 200amp fuse and put the pos lead directly from the battery to the pdb.
Now that I've done that, the car no longer cranks.

I've checked the following:
- positive and negative side voltage drops relating to the starter
- 12.6v between ground and the starter solenoid when key turned on start.
- 12.6v at starter battery lead to starter body
- 12.3v at starter battery lead to starter body while trying to crank
- solenoid is only pulling .3A
- took starter out and brought it to oreilly, it tested out to be good.
- put a screw driver from the batt lead to the solenoid connector and the starter cranks.
and maybe a few more checks I can't think of right now.

What should I be looking at right now? why isn't the solenoid putting out enough current? partial interlock switch issue?
