2010 town and country will not start from time to time?

The problem has to be diagnosed ( spark -fuel -injector pulse ) when it occurs other wise things will check out normal . Does it turn over ( crank ) , do you hear the fuel pump prime the system when the does that ? Look for any obvious wring problems and motor to chassis ground . And no , most pro mechanics don't like those kind of problems , they like things that plug and play , they ain't got time for that $h!t

Unfortunately intermittent problems are hard to diagnose. But you only need 3 things for an engine to run. Fuel, ignition (spark), and compression. When the engine refuses to start, one of these is missing. We know you have compression because the engine will run most of the time. So it's going to be a fuel problem or ignition problem. Most times intermittents are caused by electrical problems. To find out if you have a fuel problem or ignition problem buy a can of starting fluid from your local auto parts store and bring it with you when you go out for a drive. When the engine refuses to start, pop the hood and spray a little starting fluid down the throttle body. If the engine will run a few seconds on the starting fluid you have a fuel problem. Possibly a dying fuel pump or bad fuel pump relay. From there you can try hitting the bottom center of the gas tank with a hammer a few times. If that gets you going it's definitely the fuel pump. If the engine will not run on the starting fluid at all you have an ignition problem. Bad ignition coil(s), faulty spark plug wires, failing ignition control module, or even a bad crankshaft position sensor. Also, look for patterns. Does it act up when it's damp or raining out? Does it act up when the engine is cold, like sitting overnight? Or when the engine is hot, like after a recent drive? Once you determine what the problem is, fuel or ignition, and any patterns, you can figure out what components are responsible. BTW, there's very few good old fashioned mechanics out there anymore. The 18 year old "tech" who is looking at a vehicle has no idea what he's looking at! If the computer doesn't tell him what's wrong, they're completely clueless!! A few years ago I wasted $700, at the Dealer, trying to get the security system fixed on my '94 Fleetwood. I knew their diagnosis of the ignition lock cylinder was wrong, successfully got into an argument with the service writer, and took the car home no better than it was when I dropped it off. After buying a factory shop manual and doing much research on the system, I fixed it myself! It was the BCM (Body Control Module)! Hope that helps! Jim

That is a problem with todays techs, if there is no code then that’s where they stop. They won’t even look at TSBs or flow charts anymore. All the good techs that were out there are retired or very close to it. Maybe you can get lucky and find a tech that just keeps his hand in to work on your vehicle. Good luck.
