Hello,

My 97 Saturn SL1 has almost 150,000 km on it. If I don't plug in the block heater in the morning, it will not start up at all. If I do, then it will be start ok. At first, I thought it is the cold morning we have in Canada and I changed the spark plugs hoping to solve the problem. At first, it seems to work for a few days. This morning, it was raining and the car won't start. I wonder what else I can do myself before I bring the car to the dealer.

Thanks in advance!

Nikki

whats the outside temp? ever have the ECT replaced? age of the battery? age of spark plug wires?
