i have a 91 s10 with a sbc. it sat for a month without starting it while i was moving. i go to start it last week and nothing. i check fuel pressure(its carb) and 7ish psi. and it sprays in the primaries. so then i move to ingition. week looking spark so i test the coil and moduel. both turn out fine which should be the case the dist. only has 1500 miles on it. i notice a little build up on the contacts inside the dist. so i replaced it and the cap. then i put new ac plugs in and still no fire. its getting 12 volts with key on and 10-11 while cranking. so now im stumped. i have fuel, air and spark is my only issue. what now??? i havent tested my spark at the plug since my last starting atempt but its late and i was by myself. any ideas? thanks gary
