1989 Buick Lesabre 3800 cranks, fires, sputters out
My 89 Lesabre cranks, fires, and sputters out. Won't hold an idle. I have replaced the fuel filter, crankshaft position sensor, coil pack, ignition control module, harmonic balancer, and serpentine belt to no avail. It's getting spark, the fuel pump is engaging, the fuel injectors are spouting fuel perfectly fine. Like I said, it starts up, but then it just dies again. Any ideas? Any help you can offer from your experience with these engines is much appreciated. Would love to know what I'm missing.
