You need to make sure you are almost empty on fuel because the tank can be heavy. 1.Disconnect battery terminals. 2.Disconnect filler neck. 3.Loosen the gas tank straps. 4.Lower the gas tank and remove all fuel lines and wires. 5.Remove fuel tank and remove the the clamp or ring that traps the fuel pump.You might need a screwdriver for this. 6.Remove the fuel pump and disconnect all wires.Installation is reverse of removal.

SOURCE: replaced fuel pump & still car wont start on 97 olds 88

You have to check for spark and fuel pressure. The 3800 motor can have a bad module (sits right below the coil pack, as well as bad coils. Also check for fuel pressure. I put a brand new dealer pump in a 93 Olds once and it was not putting out enough pressure to engage the injectors. Section 4 in a Hayes manual found at most Advance and Auto zone stores will give you the fuel pressure reading you need.

Hope this helps.

Changed the fuel pump and also got the timing. Chain changed But still want stay started. Ooh it is a 87 delta 88 oldsmobile

Have you changed the plugs and wires? If the plugs are very old, and the damper it is, the less it will stay running. Routine tuneup and oil changes on chevy motors and aside from a fluke parts breakage or abuse, they will last about forever.if it's tbi, check and clean all grounds, change the fuel filter, the module in distributor cap, (very rarely the distributor goes, *see bad ground) the coolant sensor (either sends too cold, putting too much fuel =running rich, or sends too hot, putting too little fuel = running lean) and also fuel pump (start with module, most of time it's that) used module is cheaper I used to cart spare in glove box and special bit for the screws.
If it's carbureted, check the fuel filter in the inlet at the carb, and also if you already changed the fuel pump, it might be faulty and not be pumping fuel.

1997 delta 88 Fuel pump went out. We replace the fuel pump and now the car will not crank. we took the fuel filter off and there was no gas in the filter. What would cause this issue and how do we fix it.

Check for power to the fuel pump. Is it possible the old pump was fine but had no power to it? If there is no power than check the fuse and the relay. If those check out good let me know and I'll get some more info for you.

They share the same power (fuse)
