I bought this car from a dealer 3 months ago. A great car. Excellent shape, one owner, low mileage etc. It's my 4th Park Ave, but my first Ultra. One 3 separate occasions the engine shut off at low speeds. When I got off the road and brought the car to a stop, it started immediately and ran fine for several weeks without shutting off. Secondly, on 3 or 4 occasions, it won't start. Cranks well. Plenty of battery but won't fire. After a short wait. Maybe 10 minutes, it starts right up. What gives? Are these problems related? Rob

IF you were my customer, I would suggest having it towed in when it doesn't start, or if the shop is willing, have them test it wherever you are when the no start happens.

Intermittants are a nightmare sometimes and likely the previous owner traded it in because of it.

I have seen a share of crank sensors and fuel pumps fit the symptoms on these. This may also be a ground issue. Regardless, testing needs to be done when the problem happens.

There may be codes stored in the computer that can shed some light.

When the no-start happens a fuel gauge should be hooked up to check pressure and a scanner installed to check for crank signal.
