SOURCE: starter removal

Don't rely on a Chinese jack to keep the car high enough to crawl under it.  Use wheel chocks of some kind and jackstands after raising the car high enough.
The battery will have to be disconnected; take the negative (ground) clamp off first, then the positive; keep in mind that disconnecting the battery is going to play havoc with alarm systems and perhaps anti-theft protections on the radio. Perhaps someone here can describe better what to expect.
The starter is generally snug to the engine with one end free, the other inserted in the bellhousing of the transmission where the flywheel is housed. The first thing to do on the starter would be to disconnect the cable coming from the battery or solenoid; this will be a heavy gauge cable. Depending on whether the starter has an integrated solenoid or not, there may also be a light gauge wire connected which carries the 12 V from the ignition switch (start position) to operate an integrated solenoid which is simply a relay with a coil powered by the ignition switch and a set of very heavy contacts that are closed with a bar to supply the 120-200 maps of starting current.   
There probably won't be more than two beefy bolts (could be 3 though) that hold the starter onto the bell housing and pass through flanges on the starter.   
Starters are pretty heavy for their size (lots of steel and copper) so don't get your face too close to it once the bolts are removed.
A cautionary note: be sure you really need a starter and not only a non-integrated solenoid which is much cheaper to replace. You should be able to verify this yourself if you have no manual; trace the path of the (disconnected) positive cable. If it goes straight to a hump on the starter, then it is an integrated solenoid. If, instead, it goes to an object not attached to the starter other than by another heavy cable, this is the solenoid and can be replaced separately.

SOURCE: 1987 Buick Century, V6, 2.8L will not start. No

the 3 coils are mounted to the ignition module and as long as the sensors that signal the module to fire the coils individually are working I would try a module especially if all 3 coils are not firing..also if you have an ohmmeter for checking electrical resistance, the spec for the coils are 5000 to7000 ohms, measured between each coil from tower to tower (ie) #1and#4 2+5 and 3+6 any more than that and the coils are hope this helps also check the spark plug wires at each end maximum resistance is no more than 1000 ohms per inch,,,good luck

Testimonial: "Coils and plug wires check good. If the ignition switch is bad would it give a symptom of not controlling spark to the coils"

87 buick century 2.8 has spark, and fuel, no start, backfires thru intake-not all the time, timing chain, and gears replaced, timing is correct, replaced icm, cam sensor. any suggestions?

double check the coil pack wiring to be sure they are correct-popping through the intake is usually an indication of bad mechanical timing (I know you said you checked it but that is a big possibility) or a leaking intake valve-or wires not run properly to the plugs.mikemt_18.gif

87 Buick Century, it runs at a high RPM at highway speeds. Does anyone offer a transmission with an overdrive to replace the stock three speed.

There was an overdrive transmission available in that year and most had except for the base cars.If you could find the transmission ( Good luck with that) you would need to change axles , motor mounts and maybe part of the subframe.Both had computer controlled lock-up torque converter but were wired differently and i think you would need to change pcm and do some rewiring.You can buy a lot of gas for the two or three thousand you would spend trying to make a 24 year old car a little more feul efficent.My advice is to save up and get something easier on gas.

87 regal will not start. i turn key starter just clicks but does not begin to turn motor. ita new napa lifetime starter

Hi check the batery conection to be well tigth and clean, if they are ok you have to check the starter motor an the starter solenoid, very often its only brushes. allso if you rotate the crank shaft some times fix the problem. and dont forget to check the batery charge.
