First off thanks to the people who run this forum . Im finding a lot of good stuff here . Now the issue at hand ,about a week ago replaced fuel pump with after-market pump worked fine for a day or two .Then in it would stall out intermittently so I replaced fuel filter worked fine for a day or two then wouldnt start after sitting for awile shot ether into air intake it would start.I checked fuel pressure it was 60 so thats good ther does not seem to be any leaks under plenum not real sure where to go from here . Any advice would be greatly appreciated .
