Hi there I have a 2000 Honda Civic with a 94 gsr swap I am having trouble with it starting it will crank for about 10 Seconds and then start I am running a obd2 b16 dizzy could this be the problem?

I’ve had issues with the fuel pumps allowing the fuel to drain back into the tank out of the fuel rail while the car sets for a period of time. Try cycling the key on for a couple seconds without cranking then back off, then on for a couple and back off, then try starting. If it starts right up after doing this, you have a fuel pump issue.

I have tried all of this and nothing has work I just changed the y8 fuel pump to a gsr fuel pump and still nothing the pump primes but there is still no pressure

Still haven’t found the problem any help anyone? Brand new fuel pump and relay and still no fuel pressure
