I'm pretty sure the Main relay doesn't control the injector resistor box on a cb like it does on civics.

Right now, you have to figure out for sure if you are getting fuel. I know you said you soldered the relay. Can you hear the pump priming at all?

hhhhmmm

yes i do it was running good at idle and when you rev it it would sputter then all of a sudden it turned off now it wont start (crank no start)

Check for gas, then check for spark

Stick a test light to the neg side of the injectors and see if they are firing. Or see if there's an overpowering smell of gas in the exhaust after trying to start it a few times.

If you have fuel pressure, are getting spark, but there's no sputter or even an attempt to start, chances are the injectors are not firing. Even with bad timing it would still sputter or something so I'm leaning towards injectors not firing which is going to be the cause of the ECU not getting a proper signal for a sensor (could be a bad ground or sensor) or possibly a bad ECU.

Any CEL codes?
