New battery, fuel pressure regulator & control module (none for this problem). anybody know what sensor would cause this problem. The manual is a great help, it says choke inoperative. I realize the choke is inoperative since it has TBI and no choke.
There is no mechanical problem so difficult that it can not be overcome by brute force and ignorance.

It was the coil. It would get real dirty from time to time, from being run on a rural mail route with miles of dirt roads. When this hapeened it would short out and spark to ground through the dirt. I would clean it off with some soap and water or gas in a pinch. Than thouroly dry it off and I would coat it with polyurethane. Than it was good to go for another year or so.
Don't know if this helps or not. | | |

#24448 02/12/2004 12:54 PM | Joined: Dec 2003 Posts: 103 Member | | Member Joined: Dec 2003 Posts: 103 | I have to go with the coolant temp sensor. Had a 88 Celebrity (high mileage). When it was 15 - 25 degrees and relatively high humidity and having sat out all night the car would have to be cranked for over a minute -- many false starts and backfires -- once started it ran fine. I just carried a wrench and an extra sensor as I was on the road 5 - 6 days a week and being late for an appointment was wasn't an option. Less than 5 minutes work and I was on the road again. | | |
