Have you tried to start in the last 3 days? ....seriously you need to give us feedback on our comments......

----------

As been stated you proably should replace the fuel filter and then do a fuel pressure test. the filte ris about $10 and the tool is about $10. You can borrow a fuel pressure tester from the stores or buy one from harber frieght for as little as $20 here is a link to the FF swap. Go to post #15

we need feedback......does it turnover/crank and just not start....or does it not crank over at all?...........if it cranks over have you tried spraying starter fluid into the TB......etc, etc,.......plenty of help here but we need detailed, coherent feedback....
