My friend has a problem with his rx7 FD, it will startup idle for a second but then die:/ We have checked fuel pump, fuel lines, cables, un-flooding the engine and some other things that i dont know.
Could the apexi power FC lost the tune that it had?

 

What else has been done to the car as of late. Have you changed anything? Grounds all good, plugs fouled, vacuum leak after map sensor, map plugged in, could be many things need a little more on the car itself.

 

If you gas it up a little while its running will it stay on?

 

What happened or what was done to the vehicle between when it was running and now that it won't stay running?

You need to provide a little more history of the problem.

 

We dont really know the history of the car that well, we checked the cables that goes to the ECU and some of isnt even connected, will check them out before doing anything with the car
