The cap should have the number 1 next to one of the plug wires. If it doesn't, take out the number one spark plug out and turn the engine by hand until the compression stroke is felt by placing a finger in the spark plug hole. Watch the timing mark on the dampener come up to TDC. Noe look to see which plug wire the rotor is pointing to. That's #1

SOURCE: 1990 buick lesabre when in drive seems like its in neautral

Hello, I'm not sure if you are still dealing with this problem, but here are a few tips.
1.When the car is running and at normal operating temperature, check the transmission fluid level. If the transmission fluid level is low, this will cause the Transmission to slip when in drive.
2.If you transmission fluid level is low, this usually indicates you have a leak. Transmission fluid does not need to be changed like other fluids such as oil.
3.You may also want to add a "stop slip" agent to you car, this may help or possibly correct the problem.
4.If all else fails, I would recommend you take you car into a certified Transmission shop. Please vote or rate this reply if you found this reply helpful.

SOURCE: tranny leaks on 1990 buick lesabre ( also shifts hard)

aarondevin: In order to validate the severity of the your problem, you have to first determine where the leak is coming from. You will have to securely raise the car (on jack stands)and clean the entire area of where the leak appears to be coming from. Once you have cleaned and located the source(s) of where the leak is, post where the leak is coming from. I will then be able to provide further tips/solutions on what step to take next. Please vote for this reply if you have found this to be helpful, Thank you

SOURCE: 1990 Buick LeSabre windo is stuck open.

The door panel will have to be removed.Look for all screws and remove them.Then pull panel off gentle.The little plastic keepers will pull out,some will stay in the panel,you will have to pry the ones in the door out and place them back in the door panel before reinstalling the door panel.Look for a broken gear,or I think in this case,a broken gear tape.also the window guides(may be not all of them)will have to be replaced.Then fold around the window,and fit in the track.I really can not tell you much more,this is the best I can instruct on this item,If I can still be of help,please ask.

What should the timing be at on a 1984 buick 231 3.8 engine, recently rebuilt

Assuming the engine was re-assembled correctly with the all timing marks properly aligned, and the number 1 piston at top dead center in relation to the timing marks on the crankshaft, camshaft, and counterbalncing shaft, the computer sets the timing.
These are great engines, but they can be fun to work on, if you know what I mean.

Contact your local Ford dealer. They may make you tow the car in or just provide proof of ownership (registration, bill of sale etc) that has the VIN number on it. They can find the right key with the VIN. Hope this answers your question. Best of luck.
