Frgyjmpr2000,

The sensors are how the computer knows how much fuel to inject and when to pulse the injectors ON for various circumstances. If, for instance, the coolant temperature sensor is out of range, the computer will recognize that and use a default value for starting and running. This is known as "limp" mode and results in poor performance but will get you home. Sensors can also supply information to the computer that is wrong but within the range the computer recognizes as good data. That can cause major drivability problems but shouldn't prevent the car from starting; it will run like crap but it should start.

See the other post I left this morning for a suggestion. If that proves out to be a dead end, you can post again on this problem. (Start a new thread, they get difficult to follow once the thread gets longer.)

If your friend isn't so frustrated that he wants to give up, we'll get to the problem methodically. Don't buy any more parts until you have test results to verify the fault. As I mentioned in my very first response to your request for help, replacing parts as a troubleshooting technique is expensive and frustrating.

Tell your friend we here on the board will be more than happy to guide him as best we can. Meanwhile, he NEEDS a service manual. You should be able to find a Haynes manual for your car at any auto parts store. A better manual is made by Bentley Publishers. I think you might find that at Barnes & Noble; certainly you can buy it on the internet.
