First time...does turn over just wont's like it's not getting any fuel.

When driving van will start to backfire and act like its going to die. Usual happens when the gas tank reaches a half tank.

My inside lights do not come on when I open my door

when you get up to around 50 mph the transmission will make a loud bang and then the van will jerk this only happens once in a while

when you stop and start right back up the right rear brake will lock up for a few feet before letting go

this started after it overheated while my wife was driving

How do I fix the security so the van will start

Not getting the fuel, I replaced the inline filter, but still nothing.

The rear doors don't open and close the way they should all the time. And the buzzer stays on saying a door is open when they are closed.

My van is displaying the low oil pressure alarm. We changed the oil filter without any help. I can'tafford to pay to have work done. I am trying to find out how to cchange the oil pump myself. Any help would be appreciated.

I had the oil changed as was suggested but the oil light is still on, what could it be?

Failed emission testing came back with P0446 went and had diagnostic check out the said I need a new charcoal canister and purge valve.

When I Start car the headlights do not automatically come on and there are no rear or interior dash lights. Also when car is off lights are turned off and he is out of ignition and I open the driver side door the car dings like something has been left on but it hasn't. When car is running or off I can manually turn on headlights and they work but I still have no rear lights or interior dash lights. All other rear lights work. This is a huge problem I need to fix it I am a Widow and don't have much money so I need to fix this on my own can you help me?
