2000 Civic Si with a B20b short block and a B16 cylinder head and skunk 2 intake and the 2000 B16 ignition with 16,000 miles on the engine. It just started stalling out and not restarting when the car got warmed up. I have checked everything besides the ignition and fuel pump, I hear the fuel pump but can't tell if there is enough psi to allow the engine to run. It back fires and stalls out when you hit the throttle and the tps and map sensor work fine from what I see in the data logs. But it will not restart when it stalls out and the spark plugs are dry and not wet or smelling like fuel. If anyone has any ideas for me to look into of why it stalls and won't restart please let me know.

Thank you

 

Exactly how, and on what, is your setup tuned? What values is your wideband giving you when the engine gets rough, before it cuts out? When you try to re-start the car, is the CEL coming on for ~2 seconds, then turning back off?

 

Check for swapped sensor connectors.
