Hi, I own a 95 e250. Pulled the into the gas station to get gas. Shut van off. Paid/pumped gas. Then I went to leave and it acted like the battery was dead. Swapped batteries no diferance. Got a jump, yay it starts. Go to a buddies, shut it off and tried to start again...nothing. so my battery meter shows not enough power, about half of normal. Been troubleshooting for days.. figured maybe you guys could help. List of what Ive done. Switched the Solenoid. Cleaned the wires going to starter. Please help. Thanks.
