1991 V6, 170k miles, auto transmssion:
While going up a huge hill last night at 25 to 30 mph, engine kicked down to a lower gear to get the torque it needed to maintain speed. About 5 seconds later the engine lost power and the car coasted to a fairly quick stop (going up big hill). All the lights on the dash were on.
The engine turns over nicely, my imagination says it sounds like its turning over TOO easily like a timing belt broke...but I know this has a timing chain.
No spark at the plugs...none at the coil. I found myself wondering if a temp sensor could disable the ignition system...I found that the radiator cap had been leaking a little steam and water whe I opened the hood last night, though the temp gauge on the dash was reading normal.
Had wife pick me up and bring me home so I could figure out how to check the DTCs, which is my next step. I'll go back to the car tonight after work and pull the codes, check the crank sensor I've read about that should be in the distributor, check compression on a couple of cylinders, and verify there's fuel pressure.
Any tips on most common failures in this scenario? Any guesses on what it will end up being?
edit: OK, upon further research it appears the V6 may have a timing BELT, not a CHAIN. Damn! At least it's a non-interference engine...right?
