I have a 1996 Mercury Grand Marquis. It has a No Start but Cranks OK problem, that is very intermittent.?

Question

It never fails in the morning. From that, I concluded that it might be heat related and/or have something to do with not locking the car, while parked in the garage. When it starts and runs, it runs normally. It never stalls. I have replaced the following: 1. Fuel Pump, 2. Fuel Filter, 3. The Fuel Injector Regulator, 4. ECC (PCM) Power Relay, 5. The Fuel Pump Relay, and 6. The Ignition Switch. I even bypassed all electrical components controlling the Fuel Pump. I did it with a push button switch. When it fails, I press the push button switch and can hear the Fuel Pump run. But it still does not start. From that, I concluded that it is not a Fuel Delivery problem. If I leave the car sit long enough, it will eventually start. It's driving me crazy. Can anyone help?

Have the gnition coil checked, sometimes when they get hot because of an internal short.They can cause for starting failure when engine is warm.You may also want to check the coolant sensor, ground it out when engine is warm and no start.Replace if engine starts.But this should be causing the check engine light to come on.Hope this helps.
