Code 42 is Electronic Spark Timing Failure. Make sure the connectors at the distributor are clean and tight. Also the MAP and coolant temperature sensors are involved. Check their connections as well. Check the vacuum hose going to the MAP sensor. Be sure it's not kinked, damaged or broken. HTH. -Jim

Thank you for your reply. I will check those 2 things, but would a kinked MAP hose or a faulty ECT cause the vehicle to have no spark at all, I would think the vehicle would still start with those 2 problems, or at the very least have spark from the coil.

It probably would start with the kinked vacuum hose and faulty ECT but if the wiring for those sensors is damaged or shorted it may not. HTH. -Jim
