Like title says, my was cold when I started it it ran for no more than 20 seconds then shut off....very weird. I do hvae an external coil and a msd box but I have already checked for spark and thats good and fuel also. Rotor and all other possible things are still good like (batt. fuses, ect.) thisa is the 2nd day my car hasnt been running and I dont know what else to look for. Very frustrating as you might be able to imagine. If I keep the throttle at 100% while trying to crank over it barely putters but definatly doesnt sound healthy. The plugs were a little damp from probably flooding out the cylinders so i cleaned them and still no good. 1st problem since drag 3 install any help would be very appreciated. thanks
