car wont start
i have a 1986 iroc z28 i put a fresh battery in it and tried priming the carb and cranked it over in intervals for 3 mins aproximately. i replace the fuel filter in the carb and tried again same things. the only things i could think of would be spark plugs so i took them out today and will buy new ones tomorrow anyone have an idea on what else it could be? btw i have fuel i got some on my hands today when a friend cranked it over before i was ready and fuel flowed real good.

Re: car wont start
that would be a no spark, no start.
no start = 1 or more of the following
-spark
-fuel
-compression
start w/ ignition. check for spark from the coil. should be very bright purpleish whiteish color and it should be able to jump a 1/8" gap at least. if no good, find out why.
fuel on your hands doesnt mean anything. easiest but most dangerous way to check for a fuel delivery problem is to spray some 2+2 down (or pour gas) into the intake, then see if it starts and runs a little while. (disclaimer: keep a fire extinguiser handy, just in case) if it runs, you either have not enough fuel or too much air(large vaccum leak) find out why and fix.
compression doesnt usually just vanish usually unless the timing set rounded off. check this by lining up piston 1 on the rotor w/ the mark on the balancer and the timing tab. also move it a little and watch to see how much play it has. if you haven't fixed it by now, you'll need to do a compression test, and go on from there.
