B20 swap crank but not starting

[93EricB20T]

hey guys, just did my first swap. I have a b20 in a 93 4door. Iv'e been at it for days trying to get it to start. I have fire at the plugs, I have fuel coming up and its in time. I can't figure it out. I have done everything I can possibly think of to get it to start. Any suggestions or something I have missed? Thank you guys in advance.

We would need to know everything you have done for troubleshooting up to this point to be able to tell you if you are missing anything. Saying you have tried everything isn't a sufficient reply as that isn't possible or the car would be running.

All the sensors plugged in/wired correctly? Do you have the right ecu? If so do you have it wired correctly and have EVERYTHING needed for that particular ecu? Do you have all the power and ground connections clean and clear of any rust or dirt?

I have fuel coming to rail, spark at spark plug, ecu is a p28 with a base tune for the b20 to start and run, all grounds are good, timing is perfect. we have done an ecu reset, all fuses/relay are good.

Car had a turbo LS running in it then spun a bearing(i bought it here b/c prev. owner couldnt afford to continue with it). I bought a low compression jdm b20 to reuse the turbo kit and already done wiring. the ECU is the one that was in the car with the LS also.
