So I just swapped an f20b into my cb7 accord
and I was driving it a few days after, I was in vtec at 7000 rpm and it just shut off
I haven't been able to start it since the only light on the dash thatccomes on is the battery light no engine code the engine light doesn't come on when the fuel pump should be priming and I can't hear it priming
I tries the main relay and that didn't work I checked all the grounds and they are tight the engine does crank but it won't start does anyone have any ideas?any help would be greatly appreciated

 

3 components of combustion are air fuel and spark.....start there n see if your getting thm

 

If the CEL doesn't go on, the ECU probably isn't giving fuel either. Check the ECU fuse.

 

I checked the ecu fuse and that's not the problem either
I did find a few exposed wires one from my vtec pressure switch and the others on my speed sensor so I'm thinking something couldn't shorted

 

If you pull the injectors and crank the engine, are they spraying fuel? What about spark, are you getting that while you're cranking?

 

So I checked for fuel and I checked for spark and I don't have either I tried another ecu and that wasn't the problem either

 

I also just changed every fuse in my car and it's still doing the same thing only the battery light comes on fuel pump doesn't prime and main relay doesn't click no fuel and no spark

 

Probably coincidence that you were at 7kRPM. Look for a poor power or ground connection.

 

How do u know if the fuel filter is going bad??
