Hey, I'm stumped with this. If any of you guys have any ideas I'd appriciate it. My 93 Rx7 will start right up and run fine when the car has been sitting for a long time. But when the car gets up to opperating temperature and I shut it off (like to pump gas) It will turn over and run for like 2 seconds then the idle drops and the car shuts down. If I wait a few hours it will start up again no prob. I suspected something temperature related so I have replaced the thermostat, coolant level sensor, fuel temp sensor, jumped the fan realays and had the fans on the entire time (no effect), replaced the water temperature thermo switch, and replaced the fan thermo sensor (on the back of the block with the thermostat) I think this is some kind of electrical problem but have no idea where to go . plese help

 

how many miles on your engine?

 

just went over 100K, but the guy I bought it from said that he rebuilt and street ported it 2 years ago? you got any ideas?

 

it sounds like hot start problems but the cause of that is low compression

 

i would say do a compression test.

 

thanks for the suggestion. I'll check the compression. do you guys think that the ignition switch, igniter, or fuel relay/solenoid could be the problem?

 

Release slowly and smoothly on the clutch....
