Ive had a no start situation for a while. Sometimes the car would start and sometimes it wouldn't. When it did start the car would drive normally..it would not shut down as long as the engine was running.There is just one in tank fuel pump..regina...and the times that the car would not start there was not the usual brief whine/purring noise from the fuel pump. I did all the voltage testing and resistance checks of the fuel pump and determined it was not the pump itself but a power interruption .In my case it turned out to be a corroded (fuel pump) connector (big pink wire ) located inside the trunk next to the fuel fiiler neck.The trunk lining and protector shield under the lining must be removed to see this connector..assuming of course your setup is like mine..good luck and post back...cheers
