SOURCE: buick lesabre nightmare

Need to get a scan tool and look at the data stream while it is running for alot more info.Also any trouble codes.Sounds like initially,the engine isn't getting any fuel.I would have a pressure gauge connected to the fuel rail on the engine,so i could monitor the fuel pressure while all this is going on.Items to look at on the data stream would be timing,what timing is the PCM commanding for the engine.Also,have you checked for continuos power feed to the coils during this no start condition,and fire at the plugs while cranking.You could possibly still have spark,but maybe it is extremely weak?I have seen bad ignition switches cause weird problems before too.Many things power up through the ignition switch,just a thought.Have also seen bad PCM's cause strange problems..38 volts is a little on the low side for GM.Usually see those at,at least .50 and up,and rise steadily while pressing the throttle,up to just under 5.0 volts.Potentiometer with 5 volt supply.Vacuum leak can be checked with engine running at a steady idle speed,spray brake cleaner all around the intake manifold and listen for engine speed change.

It could be the fuel filter. Check fuel pressure and volume.

SOURCE: 2000 LeSabre starts but runs very rough and stalls. After

My 2002 Lesabre (app 115000 miles) started something like this. Also the loose gas cap had been coming on for quite a while. I replaced the vacuum line from the air intake to the fuel sensor. It is under the engine cover (twist off the oil filler to remove the cover). There are two hoses together that come of the air intake. The small one goes to the top of the engine. The other goes across the front and makes a 180 turn back to the sensor. Chances are the 180 piece is cracked. It all comes from the dealer as one unit. $25
Seems to have fixed my problems. So if your car is running a little rough. Shutters under load. If the gas cap loose is coming on or probably a number of symptoms this might be the answer. I would replace this item. A cheap try.

You could have a vacuum hose disconnected or a hole in a vacuum hose. See my "How To" on finding a vacuum leak.

Fast idle


Sounds like your throttle position sensor is bad.
Take it to Auto Zone and ask them to pull any computer codees that may be latched. Not sll codes trigger the check engine light

1987 Buick LeSabre is idling too fast


Check for vacuum leaks. I find mine with spray carbureter cleaner. Engine will speed up when leak is found. Check the hose from the cruise control to the three way tee. The black tee turns grey and falls apart resulting in a vacuum leak. Should be on drivers side firewall.
