My wife came home all the dash warning lights lit up and it stalled. It turns over very well but will not start, I have done the following: bypass fuel pump relay at the fuses (I hear the main pump), swapped known good relay, 951 ECU, Power Stage/Ignition module and 016 AMM. Disconnected electrical connector to AMM no difference.
I checked the 4,000 mile old timing belt and all is lined up as it should be.
New Cap & Rotor, I get a good spark at the coil and spark plug. Crank position sensor and Fuel Pressure regulator is less than 2 years old.

About the only thing left that I can think of is the main fuel pump, does anyone have a good way to check the pump without a gauge? The plugs do not appear to be wet after all the attemps to start, so I may not be getting ample fuel?
Does anyone have any ideas to check something else I may have missed?

I swapped the ECU before checking for Codes but there were none after several attempts to start.

I would appreciate any help you can give me as this is my wife's car and down time is not an option for her or the 2 pushy daughters and son that need to be chauffeured everywhere on demand.
Thanks
Dan
