could have fouled the plugs or crossed the wires, it's easy enough to do. the connector for the coil pack may not be fully seated also.

if the plugs and wires are ok, it could be an issue with the coil pack or icm. are there any codes?

icm= ignition control module. located behind the battery on the radiator support. you can use a paper clip or jumper wire to get codes from the check engine light. see if there are any codes first then see if all 6 towers on the coil pack put out spark.

Yes after he spent a week n half doing head gasket n backyard with it in the truck with just a socket wrench. He had to re due the intake a few times we still need intake cover gaskets but he sealed it with some gasket sealer for right now
