If all of the dashboard lights do not work at the same time on a Pontiac Montana, check the instrument panel relay. The relay is located on the firewall in the engine compartment.
Check in the harness down at the starter
check your alternator or make sure the starter is on correctly
if its not under the dash check under the hood
Check front end for play.
You should check the thermostat and the fuse for the heater.

It depends on your van if you have the regular or extended version. Check the owners manual.
check the overhead switch make sure its on if not that you have a blown fuse
if engine will not turn over, check fuses first. then check battery, starter motor, starter motor solenoid and ignition switch
were is the starter relay fuse on a 1999 Pontiac Grand Prix
check the owners manual
I believe they are located on the starter.
check in the trunk, or under the back seat.
The water leak in the Montana could be anywhere in the coolant system. Check the radiator, heater core,and hoses first, as they are common places for the leak to occur.
Check the tire balance. Also check the tie rod ends and ball joints for wear. These are the most common places to start.
check specs sticker by lock mecanism on driver side door for corect tire side.
Remove starter,. Check brass bushing located in bell housing, it controls torque tip of starter. Replace it !
If you're running a jumper across 2 of the three terminals and it starts then you need to check for power to the 3rd terminal (key in crank position) that triggers the relay. Maybe a broken wire in the relay plug or further up the circuit?
check the fuse to see if it is blown or replace the fuel pump relay under hood
Check the main fusebox under the hood.
Good Chance this is caused by a faulty O2 Sensor. I had the engine light stuck on in my 2002 Montana and replaced rear O2 sensor and it turned it off.
Starter solenoid is attached to the top of the starter, the starter can be removed and taken to a parts store that has a machine which can check both solenoid and starter, in my area autozone does this free of charge
