?yrs.ago While backing out of parking space at Calaveras Lumber, after shifting into reverse, & removing my foot from the brake; the engine appeared to receive a huge burst of fuel which shot me backward like a rocket slamming my vehicle into and wedging it under the frame of a pickup truck parked in the same lot. I am glad I was parked and had my foot on the brake prior to this unit or system malfunction otherwise the injuries could easily have been fatal on the highway. I think this defect may be a contributing factor to the car dying recently while on my way to a Wedding Reception in Roseville, which left me stranded after dark for 41/2hrs and 71/2hrs. 2days later. I have not been able to start vehicle since and mechanics unable to diagnose why the engine is fuel starved when system parts tested appear to be in good working order. Something seems to be shutting off power or preventing power to the fuel pump and it is not the inertia switch, relays, fuses etc.. Components have been previously inspected by numerous others including dealer. No Recognizable Alert/Warning Prior to Incidents!
