Answer
Hi Jim,
Let me suggest a couple of things. First try to get the codes yourself:
Try using the ignition key: turn it "on-off-on-off-on" and leave it "on" (doing this quickly, no longer than 5 seconds). Then watch the 'check engine' light to begin flashing, then pause, flashing, pause, etc. Count the number of flashes before each pause and keep track of the numbers. Repeat the readout and verify the counts are correct. Then group them in pairs in the order that they came out, thus forming two digit numbers. You may notice that the pause is shorter between the digits of a given number, and longer between the numbers themselves. Then send me a 'follow-up' question telling me the results of your readout. By the way, 55 will be the last number (two groups of 5 flashes each) and that is the code for "end of readout".
There is also an essay on fault codes at the site:

which gives the meaning of the code numbers. But then you need to get specific info for what exactly might be the diagnostic tests or parts to replace to complete the repair. A no start with no codes is a challenge; if often means that one of the sensors is off value but not so much as to set a code. A diagnostic tool that accesses the sensors' voltages is then necessary to spot the one that is not in the right range.
Second, carry along a spare spark plug and the next time you have a no start try removing one of the plug wires from the engine and put your spare plug in the cap. Hold the threaded shell of the plug against the cylinder head and have a passenger or helper try to start the car by cranking it for 5 seconds. Watch to see if you get spark for 5 seconds, 2 seconds or not at all.
Then write back with what you have observed.
