1995 Pontiac Transport 3.8 mileage: 125,000. My van is intermittently jerking on acceleration. The battery gauge will go from normal to 18, all my lights will dim and go really bright, and the van will jerk. I've had the alternator replaced, battery replaced, fuel pump replaced, and my transmission was just replaced. Now these all needed to be replaced, but I was having the problem before these were replaced. I've dropped about $2,000 into this van, I just want it done.

Your problem is probably related to the 12-volt power system in your car. A main power connection goes through the firewall. Within that connection is the main 12-volt power supply. These connections get corroded and cause the kind of trouble you described. In addition, check the battery cables for corrosion and or poor connections. It is also advisable to check ground connections to the engine compartment.

When a fuel pump goes out it can do so one of two ways either it can quit and stop working or it can fail intermittently causing the engine to stall or not start.
