Intermittent Starting Problems
Sport with 93000 miles recently developed an intermittent starting problem...will start and run fine and all of a sudden will crank but won't start but after a few tries and it sets for a minute will start and run fine -tried starting and stopping a couple of times after that with no problem...will start and run fine for a couple of weeks and then same problems occurs again with same outcome..diagnostics show no codes?
Possibly egr valve sticking open at times.
Next time it happens check spark plugs for fire and fuel rail for fuel pressure. If you have both I would then focus on pcv valve or egr valves stuck open.
