This Comanche is new to me. I’m trying to test things before “firing the parts cannon” as Cruizer would say. I’m pretty sure the problem is fuel-related. I know I need a new sending unit/fuel pump assembly because my gauge reads 1/4 tank all the time and the sock filter on mine looks like a Hershey bar melted inside it. The fuel in the tank is clean. Also, the pressure at the fuel rail is 31psi at idle.
I’m assuming I have to unhook the wires on the CPS to test it?
Looking for a thread on how to test the coil…
Thanks for your help
