So I am inheriting a 2001 DHS with about 15000 miles on it. The problem is that it has been sitting for 3 to 4 years. All the tires have air, the battery is dead. It'* in a garage that is attached to the house. It has had seasonal oil changes until it was parked. Never been in a accident and still smells like a new car inside. What should I do to get it going and make it a daily driver?

The first thing is suctioning out all of the old fuel. Get 10 gallons of fresh high octane fuel in there. I would want a new fuel filter and fresh oil/filter & a new battery installed before attempting to start it.
Hopefully the injectors are not plugged up, if it fires up well, that is good news.
After 4 years I would want to inspect all the brakes, read the date code on the tires to see how old they are, and consider new brake fluid/bleeding a good idea. A brake fluid test strip will give you a condition reading initially.

With these no siphon tanks, how would you remove the old fuel?
Thank you for the reply.

How much fuel is currently in the tank?
Dropping the tank if it'* full is no fun.

Why high octane fuel? Waste of money dumping it in old gas.

If you can, find a shop that can pop one of the lower fuel tank hoses off and siphon it that way. That gives direct access to the tank itself.

I think the easiest way to get the old gas out is to put a fresh and fully charged battery in the car, get yourself about 5 feet of 3/8 fuel line. disconnect the fuel filter and force the 3/8 fuel line over the hard line you just took the filter off of. Find the fuel pump relay and jump terminals 30 and 87. This should energize the fuel pump and let it drain the fuel for you. It can take a while depending on how full the tank is but you won't have to siphon anything.

Using a higher octane will boost the octane percentage of what ever left over older fuel is in there & should make it easier to start.

Or he can turn the key and see what happens.

I like the idea of disconnecting the line at the fuel filter, and inserting the end into a gas approved container.....new battery and pump the fuel out....replace the filter, add fuel, and let her rip....

I would definitely get rid of the gas especially if you don't know what the PO used. If they put Ethanol in there, after 3 years it is probably jelly by this point. You don't want that stuff in the fuel line or combustion chamber.

Coolant has probably broken down and needs to be replaced ASAP

Otherwise check the wear parts (belts, brake hoses, etc) and fix whats broken
