Thanks for the responses !

No noises heard from the engine. Has about 3/4 tank of premium unleaded, drove the car around 150 miles since last fill. I buy my gas from the same place and use the same premium fuel in my 95 BMW 540i and it just screams.

Did put the old fuel pump regulator back on, still won't start. Drove the car about 1K miles since acquiring it. Did notice that occasionally it would idle too high and felt 3 slight surges whenever taking it off cruise control.

Hate like hell to blow the rings out of it with starting fluid. I am suspecting a problem with the CIS-E control module and/or idle speed control unit. What should the voltages be at the start valve, idle speed air valve and EHA?

Thanks again for your interest and help !
