Why does my96 olds achieva 2.4l starts an dies immediately I replaced fuel pump can it be fuel pump relay

have you checked fuel pump relay?

What is model year? Does the relay have diagram on it? The load side of relay usually shows as open switch, that should be load side of relay, use jumper wire between those two terminals on the load side, with relay unplugged. That should send voltage to pump. One of those terminals should be hot all the time. This is just for testing not driving. Even if fuel pump runs, that doesn't mean it will start?

Did you use a gage and check proper fuel pressure?

As with any no-start issue, you will need to figure out if it is a fuel or ignition problem to proceed.
The brake switch problem with the shifter could be a fuse.
No start could be a relay, fuse, fuel pump, coil, or a long list of other things.
Did you check the computer for trouble codes ?

From the fuel system troubleshooting guide - 1993 Oldsmobile Achieva

Inspect Fuel Pump Low Fuel Pressure.
Inspect Fuel Pump Relay - Faulty Fuel Pump Relay.
Inspect Fuel Injector Pressure Regulator - Faulty Fuel Injector Pressure Regulator.
Inspect Fuel Pump Strainer - Clogged or Dirty Fuel Pump Strainer.
Inspect Engine Control Computer - Incorrect Operating Information Being Delivered and Sent From The EEC.
Inspect Fuel Tank - Fuel Tank Empty.
Inspect Fuel Line - Fuel Line leaky/kinked/loose/disconnected
Inspect Fuel Fittings/banjo bolt(s) - leaky/loose fitting(s)

For your next posting, in 1993, Oldsmobile produced the Achieva with four engine types:
Available engines

• 4 Cylinders, VIN "3" 2.3L MFI SOHC Quad
• 4 Cylinders, VIN "A" 2.3L DOHC Quad 4 HO
• 4 Cylinders, VIN "D" 2.3L MFI DOHC Quad 4
• 6 Cylinders, VIN "N" 3.3L FI OHV

To find the engine type of your 93 Achieva, compare the 8th digit of your VIN code to the entries in the above table.

Your starter will start to do nothing but click when you try to start the car. And you will have problems with it constantly freezin up

check and replace the noisey relay

Hello tcb476: My name is Roger and i will answer your question. The fuel pump relay on your Oldsmobile Achieva is located under the hood. Open the hood and look at the left strut tower. You should find a relay block attached to the tower..There should be 4 relays. Three of them will be in a row. The center relay should be your fuel pump relay. Please rate the answer you received as this is how we know you received the correct information. Should you need further help please just ask. Thank You for using Fix Ya. Roger

Check the Fuel Filter and Fuel Pump. Also Check under the Hood and Look for a Fuse Relay Box. Inside this Box there should be a Relay for the Starter and Fuel Pump and Crank, Also after Replacing these Take a Flashlight and Check ALL the Fuses Really good in the Box under the Hood and the one Under the Dash on the Inside.. Replace these and let me Know how it goes.

First off, I'm a great believer in the simple solution. If jumping the relay works, then replace the relay.

As far as a relationship between fuel pump operation and oil pressure, coincidence of operation.

If the new relay fails you, I'll need some more info:

• Fuel Injected? If you turn the key on (not to start) do you hear the fuel pump come on for a sec then shut off?
• Hard to start when hot, cold, doesn't matter
• When it does start, does it idle ok? erratically? High? Won't stay running? Dies immediately?
  
• Does it blow smoke? Black? Blue? White?
• When driving, does it lack power? Stumble? Stall?

Hope it's the relay
