What was the reason for replacing the pump ? Did you check fuel pressure before and after the job ?
Is the check engine light on ?

The upper intake gaskets may be leaking. They are made of plastic and metal and will leak air. Do not remove the cover on very top of manifold when changing.

Hi,
Tipping my hat to you... I would recommend going to an auto parts store like Autozone or O'Reilly and purchasing a Chilton repair manual, specific to your model. I always think it's a good idea to own a light repair manual if you're going to keep the car a while.
Good luck with the project! You can do it!!

Change the fuel filter and try adding a fuel system treatment to help clean your fuel system.

If the fuel filter and sparks are replaced-then the other possibility can be a bad injector or a bad ignition control module.Also get the fuel pressure checked in your ascender.If the fuel pressure is low then it can be possible that fuel pump is not holding charge and causing this problem.As you have replaced the fuel filter,but not the fuel pump.Get the fuel pressure checked,this will confirm the problem with fuel pump is there or its any other problem.If all that checked ok then get the alternator belt checked.If the belt is loose or worn out it can be the problem.If the alternator connections and alternator belt both checked out ok then the other possibility can be weak crankshaft sensor.Not faulty but weak crankshaft sensor.In this case the sensor needs to be removed then cleaned and reconnected and checked.
