I followed with interest the recent thread about DI failure, having had to spend around $600 to have one replaced yesterday on my 97 9000 Aero. I'm trying to understand if I did something to cause it to fail.
About a week ago, my battery died, after the headlights were on for about 30 minutes without the engine running. Foolish of me. But I jump started it and then used my trickle charger overnight and all seemed fine the next day. About a week later, after the car started and ran normally, I went to start it again after a couple hours. Good cranking but no start. I kept trying but eventually the battery ran down. I popped the hood and got a strong smell of burning plastic. Had it towed to the shop where they said my battery, although it took a charge, would still not pass a load test. So new battery. They also said the DI had fried and that was what I smelled. I'd replaced the plugs (yes, the NGK's) in early September but he said two of them were fouled. Could that be a sign that the DI was failing, not delivering enough spark to the plugs? Did I cause the failure by continuing to try to start it?
Any wisdom appreciated.
