I have been piecing back together my 87 fc (n/a) for a while and have alwaysed had spark but no fuel (no fuel, no fun). But now after i fixed the fuel problem in hopes that i can break in the engine before i get maried so i can take it on my honey moon and ultimately get her on the track, i get no spark! I'm very perplexed. I changed the crank possision sensor (well, the equivelnt), checked all the connection. Could it be either the ECI or the Main Relay? I really appreciate any imput so i can reach my goals this year!

 

For starters you replaced the Crank Angle Sensor, or CAS.

After that you should start checking connections to the spark plugs, are you sure you didn't unplug anything on your fuel problem solution?

One thing you can do is remove the CAS and spin it with the car turned on. The car will think the motors spinning and try to spark. It will probably also shoot fuel, so you may want to find a way of disabling the injectors. After that, just follow the wires to your problem.

You can find an FSM by typing RX7 FSM into google.
