You need a timing key and a timing light. the timing key gets inserted in the diagnostic connector a-b position if i remember correctly i would consult the manual to be sure.then hook up the light and set the timing like you would most any distributer type engine

I replaced the egr valve, spark plugs, and wires on my 91 cadillac Seville and it cugs

Have you checked the timing? Could be retarded. Sometimes this can be caused by a vacuum leak. Check hoses for cracks or poor fitting ends.

If you can check the part numbers stamped on the two different pumps and they are the same then that answers your question.

After changing hoses and coolant in my 91 seville the heater does not work. what gives?

If you had heat before, and not now, it sounds like you have air in the system. When the system is cold, open the radiator cap and check the level in the radiator. If it is low, fill it back up. Also, make sure you put the "tabs" in the radiator if you changed the coolant. There should be a decal that says the warranty would be void if you don't put them in. They are cheap at the dealer. Before you start it back up when it is cold, take the cap off and squeeze both hoses several times. you should see air come up and out the inlet.

It may help to jack the car up on the Pass side with the cap off let it run. putting a little 50/50 coolant in as it runs. Leave the heat on at high while you are doing this.

Hope this helps
