Ok guys, I am in dire need of some assistance. Here is the situation...I just arrived in Florida this morning after driving all night from Texas. I parked the car in my parents drive and a few hours later went out to start her up and she wouldn't crank at all. When I turned the key to allow the glow plugs to warm up, the GP Relay made a vile noise and when I turned the key further, the engine did not even attempt to turn over, it just made a single clicking noise. The noise from the GP Relay sounded like the relay opening and closing really fast. I did notice earlier this morning,while driving the car, that when I turned my lights off, my tach jumped up about 500 RPM. The same would happen if I turned the radio off. The car in question is my '84 300D. Up to now, it has been a very reliable car with no problems. I could use any and all advice given on this issue. Thanks in advance.

Mike
