Default Help solve my prob

ill keep it short and sweet. On my way to the track was doing a pull intercooler piping popped of got a cel for what reason idk got to the track put the pipe back on when to start the car main fuel pump relay made a grinding sound car would not start once i got it started after turing it on and off 50+ times was fine with solid cel. Turned it off did same ---- agian would also randomly stall and be a bitch to start got it home orderd a new fuel pump relay plug that in did the same ---- so i took my fuse box apart (under the hood) was still doing it pulled on a few wires here and there now it starts up fine. I get a solid cel crome doesnt pick it up as anything. when i jump it it reads out to be code 78. THe car is a 99 civic si obd2b-obd1 chipped auto p28 when i install the factory ecu cel goes away. but comes on after relizing there is no o2 What he ---- could be the problem.
