car: 91 hatch obd-1 conv. motor: d16z6 i have a chipped p28 that i bought from 1320 and i used it for 2 days drove about 20 miles and when i went to start it on the 3rd day there was no prime from the fuel pump. but weird multiple clicks from the main relay. i did the main relay test it was good and i did the main relay harness test and that also tested good. i switched out ecus and the other ones work fine but this p28 does not. can this be fixed, and if so how?
