So I have a question I have a 1990 CRX with h22a1 swap in it I was running p72 ECU and it didn't and it didn't run very good I got chipped p28 ECU and when I put it in a sound like it ran a lot better but then the fuel pump cut off and won't start back up when the p 28 is in there what do I need to do?
