I have a 2006 ZX4 and I recently had trouble starting my car. Once the car is warm it starts fine, but when it sits for a period of time it won't start without pumping the gas and lightly pressing the accelerator until it warms up. I replace the alternator last spring and installed new plugs and wires a few months ago. I thought it was the battery since it was the orginal, but just dropped in a new one a there is no improvements. It has 80k miles and stuck on what to do next... HELP PLEASE!!!
