(1990 Chevrolet Lumina)
in San Lorenzo, CA on February 10, 2012
my 1990 chevy lumina 3.1 ltr v6 all of a sudden died on me while driving then it wouldnt start at all. the fuel pump works the starter works it has compression so i thought spark. so i wiggled the wires and there was some wires that looked a little burnt then all of a sudden the car would start when moving the wires so i bought new wires and a new coil pack and new plugs but now it still wont start. any suggestions

If it was the high tension spark plug wires that were burned replacing them in the correct order should not now make the car not start. Was it the wires to the coil that had shorted perhaps they have blown a fuse. Both engine options for your Lumina have waste spark ignition but the wiring is different so I would have to know which engine your car has to tell you what wire at the coil pack should have power. There is a company that independent auto repair shops get their information from, this same information is available inexpensively for people that work on their own cars.. The information is year make and model specific, covering repair procedures, torque specifications, fluid capacities and specifications, service bulletins, component locations, wiring diagrams ect.... Alldata is very easy to navigate

Check the firing order and wire placement one more time. The pesky GM ignition modules! They'll work for 10 minutes until they get heat up then fail.

probably the ignition module that the coils are bolted to. it's a flat plate with a plug on it. i had a 1991 lumina with the same issue. not saying it's the fix, but a possibility.
