Been a while since I've posted, but this one has me stumped ...
Our 91 9000S (213,000 miles and AT) has developed some strange symptoms as of late. The engine will just cut off unexpectedly. Usually when the car is stopped (like at a light or a stop sign), and sometimes while the car is in motion. It's always cut out while the car is moving at 30mph or less, but never at highway speeds.
Most times, the car will start right up again, but yesterday, it refused to start up a block from work on my way in. Of course, it fired right up and drove me home without incident. I swapped the DIC with a known good one, and it was driving fine all day today. My wife took it out, and it refused to start for her. I drive over to where she is, and it starts right up. She drives it about 20 feet, and the engine dies, and it won't start.
A couple other salient observations:
1. When the engine dies, it doesn't sputter or stumble. It simply cuts out.
2. The dash lights and headlights do not dim when cranking after the engine dies.
3. When trying to restart, it cranks fine, but nothing catches.
4. This may or may not be related, but there are two other nagging problems that I've been waiting for warm weather to fix: dash lights do not work, and will randomly turn on and work for a few days, then go out. And the tachometer does all sorts of crazy stuff--it'll stay at 0, or be up at 3000rpm no matter what engine speed actually is, it'll move slowly up from 0, or sometimes jump up, then back down and then work correctly.
Anyway, that's a whole lot of stuff--any ideas what is making the engine cut out?
I'm thinking crank position sensor, or a fuel problem. What would be really helpful to me would be some tests to do, although I'm probably taking it to a mechanic for this one because of the weather.
Thanks for any input.
