[QUOTE="Joseph, post: 440307, member: 21330"] I have a spark test light and a can of starter spray to help isolate my problem, the next time it occurs. I have also seen on YouTube that the Crankshaft Position Sensor (CPS) is often the cause of my problem. I plan to also carry some freeze spray or ice water so I can quickly cool off the CPS. These three tests will be very easy to perform. If the results indicate “low fuel pressure“ might be the problem, then I will get a pressure gauge. Any thoughts on my plan ? [/QUOTE]
