I think what you have said will give me a good starting point for Diag.
I did gap my plugs at .030 as I did not have a .028.
1. Test if it will run on test fuel. If yes, then it's fuel system. If not, ignition.
2. Test plug color. If black then probably in limphome or too high fuel pressure. If white then dead MAF.
3. If good fuel and good plug color, look for code 41 or 42 which means bad tach wire and no spark so ECU shuts off fuel.
