Re: engine wont start possible map sensor prob

If the code says the sensor is bad just go ahead and change it. Once the sensor is changed you will probably find that the car will start. You will need to expand on your statement about the misfire, as far is size of engine, mileage and provide the misfire code number if you have it. All will be helpful in trying to determine what is going on!

It won't start? Do you mean when you turn the ignition switch to crank the engine, the engine won't even spin or the engine just spins and spins?
