1988 rx7 Will not crank it has a good battery can you help with this
We changed the transmission and the clutch now it will not crank. Don't know what is the problem tried everything I could think of.

Does the car have the starter cut relay. It's located next to the main relay and has one plug with 4 wires to it. If it has this relay then run voltage from the battery to the Black/White wire to see if it cranks the starter or not (this is done w/the car in neutral of course).

At the top of the clutch pedal is a switch that detects when the clutch is depressed. I remember something in the Haynes manual saying that the car should not start without the clutch depressed, so if the switch has failed, that could be your issue.
My car starts even if the clutch is not depressed though, so it is possible that mine has failed in the opposite manner (the car always thinks the clutch is in). Either way, there is a check procedure for it in the Haynes Manual, and presumably the FSM.

Diagnosing a starter circuit is pretty simple.
check for battery voltage at starter, large wire.
check for 12v on solenoid wire while turning key to start.
check resistance from negative batt terminal to block.
if that is all OK then check voltage drop.
DMM set to dc volts
one probe on starter big wire, second probe on battery positive terminal (not the battery harness)
attempt to start, you should see less than 1vdc on your meter.
do the same with ground terminal to block.
