    whats up guys i have been having a problem with my baby, i went out the other night she was driving fine but when we got out the club it wouldn't even crank up. So i left and came back the next morning, i changed the ignition module and reset my timing and she was running great that was yesterday. I go to crank her up this morning and all she did was turn over no fire is it the coil? The motor is turning over but it won't fire up, if the coil was the problem it wouldn't hjave drove all day yesterday right?

    Hi, I would check to see if spark is getting to the plugs. Also all the wires in the ignition circuit, etc..Then check the fuel system fuel filter, moisture, fuel pump etc. Thankfully with old cars you can narrow it down to spark, fuel and timing. That is what it needs to run, no computers and all the other rocket science stuff. Good Luck, Mark

    I guess you have an HEI, if you changed an ignition module. The coil in cap is the weak link in any HEI. They are epoxy filled and run hot. The coil can kill the module in some cases. It could also be the pickup coil at the bottom of the distributor. (you have to disassemble the distributor to change it.) Try moving the wires from the module to the pickup coil around. Sometimes it is the wires. MSD sells a coil cover that allows you to run an external oil filled coil. This eliminates the coil overheating problem.
