I have no engine codes. but I have put two on this truck already and the first one lasted about a week the second one lasted 10 minutes. if anyone has any idea what the voltage is coming from computer to the control module will help there is four wires not sure of the color. and then there are two coming from the coil pack. any info would be appreciated.

Poor quality replacement module, not putting heat sink compound on the module, ignition coil that has is shorted and allowing secondary ignition to back feed into the primary, and/or poor ground. If you replace the module, its a good idea to replace the pickup coil too. Use AC Delco parts if you can.

That is the most likely suspect. ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ We offer help in answering questions, clarifying things or giving advice but we are not a substitute for an on-site inspection by a professional.   Email This Post   Automotive Repair     Auto Body Repair and Refinishing     Heating or AC Issues     Electrical and Wiring     Brake Systems     Car Stereo Repair Advice     General Discussions     Car Making Funny Noises     Engine Fault Codes     Engine Troubles     Exhaust Systems     Steering and Suspension     Transmission Troubles     Tricks of the Trade Automotive World     General Discussions     Antique Car Talk     Car Shows and Events     The Bargin Bin     Motor Vehicle Inspection     Car Care Tips     Traffic Tickets     Gasoline, Motor Oils, Concept Cars and Engines     Auto Insurance, Financing, Leases, Warranties Truck Repair     General Discussions     Truck Engine Repair     Truck Suspension Repair Motorcycle Repair     General Discussions     Motorcycle Engine Repair CarJunky     Open Posting     Board FAQ's     New Board Suggestions
