oh i need to add with those main parts changed .it ran great for one day and started acting up .. i pulled the coil wire up over the  coil and at times it would start  no anymore. . does this look like a ground issue coil is good wires are good  ignition module is working .. i cleaned and checked the  body ground and the ground at the fuel tank area ..
