It would appear that either the new pump is not working or you have additional problems. Disconnect the fuel line at some point and turn on the ignition just for a moment. Check to see if any fuel flows from the line. If not, the fuel pump is suspect. All of this is assuming that you have an electric fuel pump. If it is mechanical, pour a small amount of fuel in the intake through the carburetor or point of air induction. Try to start the engine. If it tries to start then keep trying several times. This will cause the pump to pick up the fuel from the tank and allow the engine to continue to run at some point. Priming is not required on an electric pump. If fuel flows then the next step is the ignition. I would suggest having someone check for spark who has done it before. Otherwise the high voltage could give you quite a jolt if you don't know how to do it. If the ignition is suspect, it could be the coil. It could also be the module in the distributor. You have the pickup coil in the distributor also which can fail. Of course the place to start on the distributor is with the cap and rotor. Hope this helps a bit. Good luck.

If this wasn't a problem before, the first thing I would do is check the pressure at the rail after turning the key on/off a few times. I did the same thing on my GN when I upgraded the pump and it purges the air out quickly and it started right away. To eliminate the fuel pump as a possible problem, check the pressure at the rail with the key on. It's not the best way because it won't tell how much volume of fuel is at the rail, but it should atleast try and start with pressure there.

Go back and follow the diagnostics I recommended on your last post. If there is air in the fuel system, and the pump is actually operating, simply cycle the ignition key from "off" to "run" every 3 seconds for 8-10 times.
Good Luck

The Olds is a G physique and the Buick is an H physique. no longer the comparable base. maximum suitable guess is to verify with vehicle areas broker and see if the area selection for each gas pump for each automobile is the comparable. notwithstanding if it is...you're in good fortune.

You may need to prime the system. Is it fuel injected or does it have a carburetor. If it has a carburetor try pouring a little gas into the carb. If it is fuel injected you can try priming it. I do not know how to do that.
