my 90 std with b18a1 wont crank. but i know its not the starter. one we can push start it and 2 we took a wire from starter to battery. ive messed with the clutch switch and tied it together by connecting the wires together. my only next guess would be the ignition switch. anyone know how to fix this prob? thanks!! j

 

Are both 60amp fuses in the undrhood fuse box good? Is fuse #2 in the dash fuse box good? Do you hear the starter relay trying to work or not? If you have jumped the clutch interlock switch then only the relay, the starter itself, the ignition switch or the wires themselves that connect it all are at fault. Start by checking voltage on the black/white wire on the ign switch harness while the key is in the start position. If you don't have battery voltage and those 60 ampers are good then you have a bad ign switch.
