1990 Dodge Dynasty

Engine Mechanical problem
1990 Dodge Dynasty 6 cyl Front Wheel Drive Automatic 220 k miles

I have a 1990 Dodge dynasty that does not start. When I attempt to start the car it runs for a second or two and then dies. If I pump the gas when I attempt to start it it might run rough anywhere from 5-20 seconds before stalling. I have replaced the fuel pump, fuel strainer and fuel fliter. I appear to have good fuel pressure and good spark but no start. I managed on two separate occasions during this struggle to get the car to run fine but after ten days the car just stopped starting again. The second tme the car quit starting after just 24 hours.

Power the coil's positive terminal from the battery positive post and let me know what happened.
