How does a car go from not running at all, replace the battery, car runs good, now it shows 19psi on the fuel pressure. These engines barely run at anything less than 40psi.

I have no idea! It has thrown code for months now. I'm ready to go back to a 60-70 model . I could overhaul those and they were simple to diagnose! This Buick ran good, will still run but throws codes like Mark Sanchez throws passes!

Is Delphi a good brand of fuel pump? Also, guess I have to drop gas tank to get to it?

Last time I changed a fuel pump was an old mechanical on the side of an engine, so all this is new to me again.

start putting wd40 on the bolts for the straps and fuel lines now, sometimes you can get them to break loose. the pumps arent bad the difficult parts are determined by how rusted it is. if its like they get around here plan on doing some fuel lines straps, sometimes the tank gets bad, filler hose is tough to get loose when its been on there for that long.

Delphi or AC Delco are good choices for pumps.

Most likely you have to drop the tank.
Although some have a access port for the fuel pump in the trunk, of course you need to remove any liner or anything in the trunk to see if you have one, chances are you don;t have one, but it is worth looking, not totally sure what the access cover would look like if you do have one, but I found an image that may be close to what it would look like.



If it is your only vehicle you may just want to buy some new straps just in case, if they are too bad you could have to cut them, and replace them.
