[QUOTE="Jdad, post: 443655, member: 22587"] I checked connections and the pins are OK. I eliminated the plug wire by using a piece of hose and a spark plug directly from the coil. All posts provide spark except number 3. If 3 and 6 fire at the same time and 3 doesn't provide any spark why does 6 fire ? If 3 was burnt wouldn't 6 also not fire? It's a new coil pack that worked for about an hour then stopped firing 3 again. I replaced the pack plug and wire cause I had a p0303 prior. It went away for an hour now 3 doesn't fire again. Checked for voltage and signal at coil connection and all is good. Should I return pack and try another ? [/QUOTE]
