I have a 1997 Lincoln Mark Vlll, lsc. It has 112k miles, 4.6L V8
I have had a problem off an for the past 9 months. It will crank and not start, so it has been towed to the repair shop 5 times. 1st time it started when mechanic started it up and would not repeat problem so could not diagnosis it. 2nd time, they replaced " crank shaft sensor.&Quot; 3rd time, again started up after being towed there, they did nothing. 4th time, they replaced spark plug boots on #4 and #5 cylinders. The computer test diagnosis dtcs PO355 ignition E coil pri/sec circuit fault. 5th time towed last week, started again and supposedly could not repair without having the problem there. Today, 10/19 again it will crank, but no start.
Why is this happening off and on and once it gets to the shop it starts. Is there a way to diagnosis the problem while it is working.
Any idea what might be causing this off and on problem and what should be repaired.
Thanks so much for any help.
