My 2006 MPV was running fine, stopped at the store came back out, started fine, put in reverse but had to stop for pedestrian & the car died & won't restart. Scan tool shows no trouble codes. The fuel pump is working. When I try starting it, it will run rough for a couple seconds then die. Thought it might be the crank or cam position sensors so I replaced both ($32) but the problem persists. Any help/suggestions would be greatly appreciated.
