1990 Oldsmobile 88 mileage: 139,000 original. I have a very intermittent (over two years) no, start problem. Some things I have done, checked and changed have been: crankshaft sensor, spark plugs and plug wires, new battery and ECM. When it does not start, I have good fuel pressure (gauge connected) injector harness checked (Noid tester) and checked for spark at all cylinders. Runs fine for months on end then next day no start. Tries to fire but kicks, bucks and backfires. Leave it for a few days starts like a new car. Note the low original miles. Any ideas?

You have done a very thorough job of trouble-shooting your dilemma. We had a roundtable discussion of your problem and concluded that a defective ignition module that occasionally misfires is the guilty component.
