    Had the same problem....... It just started doing it about a week ago. It just stops running. I had the fuel filter changed and its still doing the same thing. I listened to the fuel pump and it sounds like it is pumping. What else could it be? It cranks to try to start but some times it will start again and some times it wont.


    Comment posted on Mar 25, 2009I changed out the ignition module. Took mine into autozone and they tested it. It wasn't that. I'm thinking it might be the camshaft sensor by the pully, not the water pump. There are two camshaft sensors. I also have heard the Mass Air Flow sensor might be the problem on this year and model. Mine is not super charged. Let me know if you find the problem and I'll do the same. Mine is blinking a code 41.

    Comment posted on Mar 26, 2009The shop is telling me that the cam shaft senors wires are needing to be replaced. (welded) I guess it sitting so close to the water pump that has been leaking made them go bad. I'll keep you updated.

    Comment posted on Apr 11, 2009There are 2 camshaft position sensors. One by the water pump, and one down by the pully. Had those changed, the wires to them checked and fixed, a new ignition mod, coolant system flushed and it has worked fine ever since. Mine was showing a code 41.

    I agree Ignintion modular testing done at Napa, autozone and places like that don't detect if they are bad. When I took mine into Autozone they checked it and said it was fine. I don't think the tests they run on them gets them hot enough. I had heard that some where else so I bought one and intalled it anyway and my car still did the same thing. Thats when I decided to take it to a shop cause I dont have a puller to get to the cam sensor behind the pully. In my case I think it was the combination of the two things 1) both camshaft sensors with wires bad because of the leaking 2) igniton mod. If I had the same problem again, I would have changed out and checked the wires to both camshaft senors first. (the one by the water pump, and then the one down by the pully. I am still not totally convinced the ignition modular was bad but since I didn't do the work I can't say for sure. It sounds like that was your problem however. Just out of curiosity, did you change the camshaft sensors or re do the wiring to them?

    Check the fuel pressure with a gauge. Is it getting any sparkplug fire?

  • Rick Reichlein May 11, 2010

    Are you getting fuel at the fuel rail on the engine, if so, then you have an ignition problem.

1991 Buick park avenue. Great driving, comfortable, good performance. When driving turn off unespected. Dont know what it is, drive great, nothing sound. Just turn off when driving.


yes it could be the crankshaft sensor that burnout,i would recommend replacing it and the camshaft sensor,now if your car was blowning the fuse that goes to the fuel pump and pump is good, then it would be the oil pressure switch thats going out,cus the oil switch is connected with the fuel pump fuse.my wife car was doing all of this to her, I even replace the main computer cus it also went out after i put new crankshaft sensor,

1991 Buick Park Avenue sputters at random, stalls-egr problem?


I would look at the Map Sensor or the O2 Sensor then the EGR Valve. As far as I know all vehicles have EGR valves. Get the Haynes Manual on your vehicle for location and replacement steps for all of these. It could also be a Throttle Position sensor or clogged or malfunctioning injector units, the Haynes manual will assist you in isolating these.
