Double check the back side plug wire connections, the side closest to the fire wall. Sometimes it's hard to get the plug wire to go on all the way. Use dielectric grease in the boots and re-install. Double check your firing order. It's easy to accidently cross one, especially on the DIS systems. The coil packs should be numbered. Check for accidentally unplugging a sensor. Hope this helps.

How do i align the starter and flywheel so that the horrible squealing sound stops at every start up?


these veh don't have a shim procedure for allignment. sounds like the shaft on the starter is bent or the bolts are not tightened or cross threaded. recheck bolts. if that's not the issue then I would return the starter for a replacement. (note: it happens, once in awhile you will get a bad part, new or rebuilt)

Removing water pump from my 1996 buick 3800


Hello fellow Buick LeSabre owner. A few year's ago I replaced the water pump on my 1994 LeSabre and I too encountered a few obsticals. After I figured out how to address these problems I was thjen able to install my new water pump. To assit other LeSabre owners, I posted the actual process on the web. See the attached link for my solution ("Deano/Illinois") and several other comments from other Buick LeSabre owners. The entire process will take you about three hours. Good Luck!

1996 Buick LeSabre coolant sucked into engine


Sounds like a leaking intake manifold gasket to me. VERY common with these engines. Are you having to add coolant quite frequently?
