Hi this has been going on for two months or so. Car with mild hesitation when accelerating and car will also start one day and not the next. Car will almost turn over and then dies,,,,After multiple tries , it will sometimes catch and then eventually the next day, wont start at all, Multiple tows !
New Cam Sensor
New Crankshaft Sensor
Air Intake Hose repaired for leaks
Oil leak repaired
Spark plugs replaced
Recent recall fixed at Dealership ( I cant remember what for at this point! ) And they could not find anything
Now they are wondering if it is the timing chain or engine compression or compression

ANY IDEAS....I am broke with about $900. spent over last 3 months...Help

Are you able to do some work on it yourself? Suggest getting an OBD reader so you can take a look at the timing and other readouts - look for an anomaly. You can get them that run on a laptop with a USB connector.

Short of that, it sounds like a fuel delivery problem. Possibly mass flow sensor (MAF), or perhaps a choke that isn't working correctly. Start from there and work your way back through the intake system until you find the culprit.
