drive a 95 civic hatch cx and sometimes is starts and sometimes it doesnt...when my stock computer (P05) is plugged in my car starts everytime..but when i have one of the two P30 ecu's in it starts and sometimes it dosent..now unless i have two bad p30s what could be the problem...is it a wiring problem that the P30s are only efected by..i have no idea i looked at it and thought it was the computer..and i had someone else look at it and they said it was also the computer...anyone?

 

Maybe it's your main relay. I resoldered the points inside my relay last week and haven't had a problem starting my car.

 

i have three..same problem

 

bump...does the computer need to be bolted down..like for a ground..i dont think so since for 4months i have it just plugged in laying under the carpet..

 

someone has to of had this problem..anyone..
