Hi there!
New owner here with a manual 85 mk2 bought in So Cal.
Engine turns but no fire up. Has new plugs and gas has been sitting for a while as last owner claimed.
Which recommendations should I follow?
A. Drain old gas and add new fuel
B. Change fuel filter or pump.
C. Add fuel additive to existing old fuel.
D. Check carb
E. Other

Thanks for the feedback.

One common problem that will prevent the car from starting that you should check is for a broken timing belt. Sometimes trying to start a car that's been sitting for years, the old rubber timing belt will just shred. Take the distributor cap off and make sure the rotor spins while cranking the starter. But fuel system is generally more suspect when a car hasn't run in years.

Need to drain the old fuel and start with fresh. Fuel pumps have been known to freeze up from sitting, but there is a procedure posted on here for how to test it very easily before you go to all that trouble. There is no carb to check, its multi-point fuel injection. If its been sitting, very likely the "cold start injector" is gummed up but that won't necessarily prevent it from starting, more likely just have to crank it over for longer. The six intake injectors are usually more robust and come back to life once some fresh fuel has circulated. If they are gummed up too, you can probably still get it running, but it may not run very well until you get them cleaned. After you get it running, it may be worth it to add some injector cleaner to the first couple of tanks, but putting additives in with the old fuel is a waste of money. The fuel filter on the left side of the engine should be replaced as ordinary maintenance. Even if weren't gummed up with old fuel, its probably way past due.

But if you bought a non-running car and the seller said it was running the last time it was parked umpteen years ago, consider there's a reason that it was just parked and ignored for so long. Its one thing if it was parked after the owner died or something, but more likely it was parked because something was terribly wrong with the car that they either couldn't diagnose or would have cost more to fix than the car was worth. That kind of makes it hard because you don't know what symptoms it was exhibiting before. It may have been running, but running very bad and so there could be more wrong with it than just being gummed up from old fuel.

First thing: pull plug and check for spark. If no spark, then do the above and do drain the old gas and pull the cover plate off above the gas tank, pull the pump out and check for rust. Just hope that its not a bad ignitor.

If you do have spark but it doesn't fire, try spraying a few puffs of carb cleaner in the intake while someone cranks it over. If you can get it to fire a bit, then you know you're missing fuel and can go down that diag tree.

If you think you have ancient gas, always drain the tank and replace it. You don't want that gunk getting into your lines and fuel filter so don't even hook up a battery and turn the key till you do that. Also don't guess, pop the fuel sender out via the access in the hatch and see what the inside of the tank is like. They rot out all the time these days.
