I Love Buicks But...95 quits!

[b. selvy]

I have a 95 Buick also that just quits as you are driving down the road. When it quits all the fans come on. Does anyone have a clue as to what is wrong?

Does it start right back up if not, got spark and fuel delivery, lots of info missing here.

It doesn't start right back up. You have to let it sit for awhile before it will start again. The fuel delivery is fine. The car has had new sensors put in and it still does the same things. I have spent several dollars on the car and it has not fixed the problem. The garages around here don't know whats wrong with the car.
It has had 2 new computers put in, cam sensor, and crank sensor. What else do you need to know? I will try to remember what else was done.

It sounds like it could be the ignition module. Have it checked out.

A faulty ignition switch (VATS wire problem) would not cause the car to stall. It would only prevent the car from being started, perhaps intermittently if the wire wasn't totally disconnected or broken. A faulty VATS module however could cause the car to stall once the engine is running. The module sends a Pulse Width Modulated signal to the PCM. If this signal is not present, the PCM will not provide injector pulses thus causing the engine to stall.

To bypass the system and take the Key out of the picture a correct resistor needs to be place inline of the wires....the car will start and run every time...(this is what is done when a remote starter is used so the car can start without the key)

Go to a local shop that installs remote starters and ask them for a "VATS pack". Many remote starters include a package of resistors, one for each of the 15 values. If the starter kit is installed in a vehicle that is not equipped with the VATS system, the resistors go unused. You may be able to get one at no charge if they're in a good mood.

Id recheck the CRANKSHAFT sensor..often the computer reports the Camshaft sensor as being bad.. and aftermarket ones suck.. bad Grounds are hard to find... If you have covered all the bases .. you have to go back around.. sorry.

we haven't been able to use a computer on the car. It is one of those that is a pain in the rear. Both of our buicks are like that, 94 and 95.

A full function scanner will work on those cars.

Don't have one because don't have the money for one.

just fixed this problem was icm/pcm after trying fuel relay and 2 crankcase sensors
