Have A Automatic "Integra 1992 Gs" The Motor Is Not The Dohc...I Recently Bought It And Came With Different Motor..It Just Says Honda Motor....

My Ecu Doesnt Work..& People Be Saying I got The Wrong Ecu In my Car...The Ecu I have in my car is # "37820-Pr4-A61"

Lol my bad its my first car so yeah trying to get a new ECU and everybodys confusing me with the ECu with pr4 and P74/75

which one do i need then??

cause i bee having a problem with my Fuel Pump Lagging to turn on and i changed all the wiring,clean all grounds, battery, changed many main relays... soo i i figured out to dissconnect the MAP sensor and i jumped to check out to throw the code for the MAP sensor and the light just stays solid.....

I also CEL Comes On, Fuel Pump Takes About Cuple Mins to Turn On and once u hear the fuel pump turn on , the CEl takes off and i can turn it on and i also changed the distrubutor and i testd/checked the fuel pump and it works......and my last guess is the ECU cause it didnt throw codes when disconecting the Map Sensor and it looks like the ecu was played with
