Question about 2000 Buick LeSabre
One or both of your coil packs are likely faulty and not all cylinders are getting spark.
A plugged fuel filter may also cause this. As well as bad fuel pump. I would first check to make sure that you are getting spark to all cylinders first. You can remove one plug at a time and lay on engine block, have someone else turn motor over while you watch to see if every plug is getting spark. Do one plug at a time. If one or two plugs aren't sparking, than coil pack is bad, If not spark, then crankshaft position sensor is faulty.
If spark is good, check for fuel pressure at fuel rail. there is a test valve on the rail. If pressure is low, then filter could be plugged, or your fuel pressure regulator is faulty. You can test power to it with a voltmeter. Or test unit itself with an ohmmeter.
