I would re-check the fuel pump work. if you spray some carb cleaner in the engine intake, does it fire. if so, you have a fuel delivery/fuel pump problem
I am Fuguring the rouble lies in there.... However FYI, I did change... The fuel filter AND that dang little pain called Fuel relay, that sits on the injector after changing both of those, I got no start....2 days latter, put a battery from another vehicle in and it turned over, but died as soon as it got to a hill....I am totally puzzled. pulled hose from filter out.... and it squirted gas when i turn the key to on..I can hear fuel pump..... just to catch you up.... any info from anyone would be greatly appreciated... thanks for the response already BTW.
