Hi, am glad to find a forum dedicated to this nice little car. I have a 2005 ZX4 that has a little over 83,000 miles on it. Just in the past month it has begun having problems starting. I used to be able to just get in without pumping the gas pedal. All I had to do was crank it and it started. Now, if I don't at least pump the gas pedal once and release it it won't start at all, it just cranks over and over. I changed the spark plugs and found that they were the original plugs, there was practically no tip left on any of them. The problem is still there even with the new plugs. I put in a container of the fuel injection cleaner and that doesn't seem to have done much either. Am thinking of changing the fuel filter next to see if that helps. I don't know much about solving the problems of cars, I can fix a problem usually if I have enough information though. Would anybody have any other suggestions of what could be wrong and what a solution might be to the problem. Thank you all very much for any help you can give me as this is the only vehicle me and my girlfriend have and it has to get both of us to work.
