Hi, The battery of my 93 passat was dead, so I let the car sit for a few months (~5). Now I have replaced the battery. I tried to start the car, but it won't. There;s lights and sounds when I put the key in, and a couple of times the RPM indicator jumped a tiny bit. But still it won't start. A mechanic says that it might be the starter motor that it might have gotten stuck and hitting it might help. But where is it? Also the coolant seems to have disappeared but there is not marks that it ever leaked out the car. Any help would be greatly appreciated!

Re: Engine will not start after sitting for long time
The starter is underneath the car on either the front twards the front bumper or the rear twards the firewall it will be going long ways from fender to fender..to take it out theres only like 3 bolts and a wire and it comes out u can take it to autozone to test it for free..thats probably the problem..the coolant i would assumeit just evaporated just fill it up make sure the cap is on tight and keep checking it

Does it go dead after sitting for a few hours? Once started and driven for several miles will it restart if the engine is shutoff? If the battery goes dead only after sitting for a while with the engine off, you probably have a bulb or some accessory that is draining the battery.
Well, it may not be getting fuel. Turn the key to "on" but not start. this will activate the fuel pump.
After a few seconds, then try to start. If it doesn't start, turn the key off. Then turn the key on and pump it a few time---only a few. Take your foot off the pedal and wait a few secs, then try to start again.
It used to be we could "prime" the carburator to get a car going but nowadays cars are fuel-injected and don't have carburators!
Make sure your battery is fully charged. Sitting that long would have weakened it. It could still turn over but not have enough juice to engage the starter fully to get the engine going. Did you try jumping it?
Anytime you plan to let a car sit for a while you should use a fuel stabalizer to prevent the gas from going bad. After you do get it started fill the tank and add some fuel injector cleaner. Fuel injectors get clogged easily when the car sits for awhile.
There has to be a code store in the computer that will tell you what might be wrong. the code is the place to start. My 99 sat for a year, and after recharging the battery and getting it started the only code I could get though, was the dead battery or disconnected battery code- but the point is, it started. Check for mouse-eaten wires at the cam sensor and the Crank Sensor. Hey- it could happen...
the battery may be shorted out. do you have a meter to check a batteries condition? if not take the battery into the parts store and they can tell you if it has a dead short in it which means the plates inside the battery have sulphated together and wont allow current to pass through them. lead acid batteries are real bad about this if they go completly dead even if they are newer batteries.
Remove plugs add a some liquid wrench, let set for a few days. They try starting, if it starts, it will smoke until liquid wrench is burned off, valves have stuck. If you ever store a vehicle for any length of time take out plugs add some light oil, replace plugs, remove distributor wire, turn engine over several times.
I had the same problem with my 93 Passat diesel, good lights and glow plugs but no effort to turn over. I could hear the relay kicking in the dash (by the drivers window.) I decided to cross the starter terminals and then discovered that the wire was corroded under the solenoid and into the body of the starter. I got a replacement starter and it rolls over fine. Now if I could get ti to pick up fuel... hahahaha
