Yet another fuel pump prob
Hey everyone.. iv been wondering these forums for awhile now as a guest but finally decided to become a member and ask you guys some ?'s.... i have the what seems to be typical no prime fuel pump... i cleaned/ checked the Therm stat housing ground everything seems fine there.. My main relay is brand new...battery fully charged.. but fuel pump will not turn on... it does turn on when i jump the 2 terminals at the main relay connector though not with the relay plugged in.... so my ? to everyone here is what do you think would be the next step to look at?.. possibly the ecu? or go back to the ground wire?... any help/ suggestions will be highly appreciated.... The vehicle is a 92 civic hatch with d15z1 bone stock
