We had the same problem in our '97. Check that your battery is fully charged and working properly, also check that the alt is working. If both of these are in working order it could be a faulty ground wire or the starter wire. Then, if those check out fine, I would start checking into your ignition switch and modular. I traced our issue backwards. If you know that the starter and the alt is good then it has to be in the electrical part of the car. Wiring or ignition. Hope this helps. If by chance it's something else please let me know. We finally found our problem in the ignition wiring. We had a bad wire going into the module. We have to push up on the wiring to get the starter to jump. Still a reliable car.
