I recently bought a non-running ‘89 FC and am trying to get it started. First thing I did was a smoke test. Found a few leaks and got them patched up the best I could. This evening I pulled the fuel line (after the filter) to make sure I was getting fuel to the rail. It was. Pulled all 4 plugs to test for spark and they all had spark. Have not tested injectors yet, but previous owners stated they had been replaced with new ones and were functioning. I suppose that’s my next move. Assuming injectors are working properly, what should I try next? I was shown a compression testing from October ‘24 with 1 rotor being 98-103-99 and the 2nd being 105-105-105. I heard strong pulses when cranking with the spark plugs out. Also, AFM “flapper” is not seized. Any ideas??

 

These types of no starts are tough. Your engine could just be flooded. Do you smell gas when cranking? Have your tried tapping the gas pedal? Or just partially depressing the pedal?
Minus those, verify the throttle position sensor. If you have experience back probing the ECU, that might yield some results. The expected readings are in the FSM. You might need to verify fuel pressure with a gauge. And hopefully nobody has messed with your CAS.​​​​​​

 

I would start by trying to pull your trouble codes (https://www.rx7club.com/2nd-generati...f-ecu-1094598/). Hopefully, you didn't have the battery disconnected which will delete the codes stored in the ECU. If so, than maybe try starting the car and it will reproduce the codes.

 

Thanks, I always forget to mention someting.

 

does both the fuel line going into the rats nest look like they have been touched?

maybe someone fucked with it and put it backwards

 

When's the last time the temp sensor behind the alternator was changed?

Change the AFM if you are unsure of it.

Make sure your existing AFM triggers the fuel pump. Turn the key to the position just before starting, and reach in and push the AFM vane open. (might need to remove the air filter box.) You should hear the fuel pump kick on.
