About 18 months ago was 1st incident - inserted key, motor clicked but would not turn over, 2nd try worked. This same thing would happen every couple months or so then started taking 3-4 trys before turning over. In last 2 weeks it was been more frequent 2-3 times per week. Today it was at least 10 times - finally I shifted to neutral and back into park then it turned over. I've googled to see if others experiencing same, seems it's a common prblem. Some say it's a problem with shifter not being all the way in park, others say it's "by a ground offset that causes the pcm to turn off the starter relay control circuit do to the double start override feature or a trs input state not valid. If the concern is gone, then add a 8 gauge or larger wire between engine and battery negative, from body to engine, and engine to trans bell housing to tie the grounds together. It is recommend to check the existing grounds and cables on the engine and for the pcm. If there is a bolt or stud, remove it and check to make sure they are clean and corrosion/rust free. Clean the effected areas and the threads if needed. Check the trs connector for signs of moisture or corrosion and clean connections". This really needs to be looked into!.
When starting vehicle sometimes the starter engages. This happens while driving and stiffing from one gear to another. Driver has to pull the relay switch before the vehicle will stop. Th key will turn off the vehicle, but the starter is still engaging. This has been an on going problem for about one year and a half. The vehicle was taken to the dealership on November 19, 1999 for this problem. Dealer not sure what is causing this problem. Please provide any further information.
