my 91 civic dx died on me. At first i thought the ecu jumper came loose. Used a new rywire harness with a chipped p30 and it still wouldnt start. Seems like the fuel pump isnt priming and im also not getting any spark. The distibutor is brand new and ive tried atleast 3 different p28s. could it be the main relay? btw its a jdm b16a with a cable b16 tranny if that helps tell what the problem is. please help.
