It may be the ignition module. For example, my FORD F250 has a module on the distributor. Inside that is two seperate circuits, starting and running. The first will tell the computer to fire the fuel injectors for starting and then after that the running circuit tells it to fire the injectors for the running of the engine. I think it fires rich for startup and lean for running. These are cheap from Romania online so you don't have to pay rediculous prices like $70 or something. Also, you can use artist style Pure Titanium Dioxide White in Walnut Oil instead of expensive Silicone Compounds to mount them on the distributor if it is a FORD. Both will transfer heat but eventually the module will burn out one of the circuits in about 9 to 11 years of running. Mine burnt out the start circuit but I could still prime the 5.8 L engine with a sunlight squirt bottle and it fired right up and went on to the start circuit OK.
