chevy 4.3 cpi help
Ok so I have a 1993 s10 blazer 4.3 cpi vin number w. It ran fine then started running rough and not idling. I started by replacing cap & plugs and really didn't change any thing so I replaced the fuel regulator and no start. Then I did a leak down test and found a leak in the injector and replaced spider injector and lines "nut kit". Did a leak down test with the key on I had 57 psi and after a minute it leaked down to about 48 psi. Still wont start even with starting fluid. Another note my oil was over full and had a gas smell so I changed that and filter.
