does this happen every time or just at certain times ie. cold start , warm start , after fueling ? what do the plugs look like ? instead of a second fuel pump you could have gotten a fuel pressure tester

Right, in cases like yours I would use a fuel pressure tester first.

Have the injectors checked or search the net on how to check. One or two bad injectors could make for a hard start.
