Replace the crankshaft and computer? Why? Computer... maybe, crankshaft, unless there is a knock in the engine, that doesn't make sense. Are you sure he didn't say crank sensor?

When it dies, does it start right back up? Can you tell me what has been checked so far?

So far timing belt has been replaced and coil pack has been replaced once the car cuts off thats it the car will not crank back up so he wants to look into the crank and wants to look at the computer. My question is is the computer located on the inside or outside of car and how long does it take to take it out?

I think I understand. First, the crankshaft isn't an issue. If I direct you, can you do some checks for me before he tears into it?

After thought... Based on which computer he is after makes a difference as to location. Keep in mind, the computer doesn't need removed to be checked. There is nothing serviceable on it.

So you don't think the crankshaft sensor is the problem?

That's what I needed to know. It is the crank SENSOR that he is checking. Yes, it could be the issue. I'm sure he has an OBD2 live scanner. All he has to do is plug it in under the dash and look to see if there is a crank sensor signal when it won't start. If there is, that isn't the problem. If there is no signal, replace that sensor.

My mechanic replaced the crankshaft sensor and that's not the problem and he said its not my starter or motor and diagnosed the computer and found nothing wrong with that he informed me that once he puts the car back together and runs it and if it cuts off again he said it has to be something electrical What can you tell me about what it can be? and if it is something electrical what could it be?

Does the car start right back up after it dies? As far as him replacing the crank sensor, it should have been checked first. That would have identified it isn't the problem and saved time and money.

As far as the problem, I need to know if it starts right back up after it stalls. Also, has he checked fuel pressure?

The coil may be the issue. These vehicles are known to have issues with the wiring to the coil. Three wires go to the coil. The center one is a 12v power supply from the battery when the key is in the on position. The other two smaller wires are switching wires. They receive signals from the PCM to indicate when the cylinders should fire. Basically, the PCM provides a ground for them in pairs, 1 and 4, 2 and 3. Check to make sure there are no damaged wires there and everything has a good connection so as not to build up heat.
