If it will run on starter fluid your ignition is ok and you are not getting fuel. That could be the fuel pump- listen to gas tank(the pump is in the tank) when you turn ignition to on(not start)-you should hear it kick in then stop when it reaches the proper pressure-no sound bad fuel pump or blown fuse.If the pressure is incorrect or the pressure sensor is bad-it will not start. The Fuel injectors are controlled by a control module that is under the dash and runs $100.00- I just replaced one.

My 1999 olds silhouette van just got s new engine put in it, it will turn over, but will not start. What could cause this to happen?

I am going to assume that this is a 3.4L and that all the sensors were transferred to the new engine from the old engine and that the old engine ran before replacing it an that all the connecton are good.
Now with that said, There are three thing required to make an engine run.
1-proper air/fuel ratio. proper fuel delivery and pressure.
2-proper cylinder compression.
3-proper ignition spark, integrity and timing.
Once you have figured out what is missing , then it is time to diagnose what is at fault.

Make sure you have fuel delivery and at proper pressure.
Determine if the ignition coils are firing.

I would assume that you are gonna find there is something lacking within thses to steps.

If no spark, you will need to verify the all the connections are good and connected at the ignition module (under coil packs).
Make sure all ground connections are good.

I can only assume that the compression on the engine is good from this standpoint, because you said it is a "new" engine.

Hope some of this will help.

I need to replace a coil pack on my 2000 Olds Silhouette. I know I have to rotate the engine. But am unsure on how to do it correctly.

you do not have to rotate the engine to change the coil packs. just turn the van off and unplug the coil pack un bolt it and pull the spark plug wires off

'98 Oldsmobile Silhouette-begins to surge at 2500 rpm and loses power. It is not the transmission but the engine begins running roughly, surging @2500 rpm when parked or when driving under a load. I have...

how about the sparkplugs and the wires, you may need to tune it up, sounds like it misfires under a load, i would start with a tuneup and go from there. the other thing that come to mind could be a bad coil pack, or low fuel presusre,if you have the computer scanned and pin point the cylinder or cylinders misfiring you could try switching coil packs or plug wires to see if the misfire move and if it does you would know if its a wire coil or plug, but if its been a while sence you had a tune up i would start with that.

My van turns off when its been running for 10 mins. or so....

It is possible that this is a coil problem, once the van has ran and shut off on its own you need to check it for spark. This could get you shocked, so I recomend you take it to a mechanic if your not comfortable! If its not getting spark it could be coil packs, ignition module (usually wont start at all) or even a bad crank or cam sensor.

Continues cranking. Wont turn over. what s my next step?

You mean it cranks but wont start (cranking and turning over are the same thing) When cranking, rap on the fuel tank, if it then runs, the pump is bad and will need to be replaced.

MY car wont turm over. it is not the babtery. is

Check the leads to the alternator and see if they are loose or unconnected. The starter malfunctioning would not make the engine die, just not turn over. Slugish turning would indicate a low batery but not malfunctioning starter. If the engine will run but not for long check the fuel pump or air leaks in the fuel system. Check all leads to the distributor, coil and sparkplugs, If the distributor cap is cracked or the distributor is loose it will create these problems.

My 1995 Oldsmobile Silhouette van shuts off while driving

I had a the same problem with my 95' Silhouette it got worse and then would not restart until it cooled off. the problem is most likely the crankshaft position sensor this is what resolved my issue.
