If it's just a teeny bit of water, the engine will burn that up after gasping a few times.
1. Connect the data link connector terminals FUEL PUMP and B+ with a jumper wire.
2. Remove the fuel filler cap.
3. Turn the ignition switch ON .
4. Determine if the fuel pump is running by listening for the sound of it at the fuel filler inlet.
5. Install the fuel filler cap.
6. If no sound was heard, measure the voltage between the fuel pump connector wire (G/Y) to chassis ground. Voltage: About 12 V
7. If not correct voltage, check the fuel pump relay and related wiring harness.
8. If you do not measure 12 V , check for continuity between fuel pump connector terminal wires (G/Y) and (B).
9. If there is continuity, replace the fuel pump.
10. If there is no continuity, repair the ground circuit.

Lots of other things could be wrong, especially with a carb this old. Air leaks around worn out shafts on the throttle will make it run lean, etc, etc, etc.
Problem in the distributor with the advance?
Here's my story! I have a 2006 Volvo S40 Lease that is up on April 1st. About 2 months ago my Check Engine Light came on and I drove the car to the dealer to get it fixed (still under warranty). They've told me the problem is the Throttle Body is dirty and they have to do a Throttle Body Service ($150). They also told me they will clean it up and run the computer test again to see if the problem goes away if it doesn't they will have to continue troubleshooting and fixing. This sounds to me that $150 can easily become thousands!
Car history:
On a very rainy day I drove the car into a big puddle of water and it hydrolocked the engine. The engine was changed at the same dealership mentioned above. I performed the scheduled maintenances and use regular fuel.
I don't care to properly fix the car, i just want to fix it enough for the Check Engine light to go away until after I return the vehicle. I know the Throttle Body cleaner is $5 dollars, but although i'm a very handy person I don't know enough about engines to take them apart. I don't even think i have the right tools.
What do you recommend? Should I try to clean the Throttle myself or let the dealer do it? Is it very easy to clean it? Take it apart? Should i take it somewhere else?
Thanks in advance....
Cleaning Throttle Bodies
Also check YouTube for throttle body cleaning videos!
Without knowing what the code # was that the dealer scanned, I have no way to guide you as to whether their approach is correct or not. You might see if Autozone would scan your car for free and come up with a code for us.
Code: P0171
Definition:
Fuel trim bank one condition
Explanation:
The powertrain control module uses the oxygen sendsor to calculate the air/fuel ratio of the engine. The computer has recognized a rich or lean condition on one engine bank only.
Probable Causes:
1. If bank one and two codes set together suspect fuel pressure or MAF (Mass Air Flow) Sensor.
2. Oxygen sensor defective.
3. Ignition misfire-repair.
4. Fuel injector problem.
Troubleshotting: N/A
OEM Brand: OBDII
The PCM has determined that during testing, the fuel system for bank 1 was too lean. (Bank 1 identifies the location of cylinder #1, while bank 2 identifies the cylinders on the opposite bank).
What do you think?
This could be a vacuum leak in/under the intake manifold or a leaking "J' pipe for the evaporative emissions systems. Use of a smoke machine can usually dig this out. So you might snoop around for vacuum leaks...that will trigger P0171 I am told.
is he right?
Anyway, I would do a Google search on "Volvo S40 P0171". Like Shifty mentioned, what Autozone gave you is a generic description. doing the search will pull up this code specific to Volvo. You can read up on other Volvo owners issues with this code. It seems it is fairly common code with a few solutions.
If you don't trust the dealership, you should be able to find an independent mechanic that specializes in Volvos (if you live near a city).
Good luck.
Another happy ending. :shades:
Not familiar with the Nubira but you may need to access the fuel tank from the trunk.
Does anyone know what is the correct fuel pressure on a 2002 S80?
Thanks :sick:

I'd suggest pulling some codes on the car and see if they might lead you to a better diagnosis.
1) keep your vehicle clean
2)change oil
3) keep your tire inflated
4)drive with in a speed limit
5)check battery regularly

Have you done a thorough check for vacuum leaks, to begin with?
I'd especially check along the intake manifold gasket.
The 02 sensor was probably a bad guess from the start.
This diagnostic tree might help you approach the problem methodically.
You might also verify idle fuel pressure with a fuel pressure gauge---I know it's a new fuel pump but it might be a lazy one. One tip off would be taking a long time to start on crank, and a fluctuating needle on the fuel pressure gauge.
