Loses power and shuts off while driving?

Hi,

If you hear the fuel pump run and nothing comes out, either we have a restriction in the fuel supply, or the new pump has also failed.

You indicated there is power to the pump. Is it getting 12v?

If it is getting 12v, and you hear it turn on, then chances are it isn't a ground or power supply. In this case, I feel the pump has failed, or you have a fuel link kinked, restricting fuel flow. You may want to remove the pump and bench-test it to see if it pumps fuel.

Let me know.

Hi,

No problem whatsoever. I hope we can resolve the issue.

Let me know what you find.

Take care,

joe

Thanks for the update. I didn't realize it was used. Chances are that is the problem. How much is a new pump? $2,700.00?

Here is a new one for under $80.00. Where are you located?

Let me know.

Hi,

That was from Rockauto.com. I put in the engine and vehicle information, and that is the only one that came up. If you want to get it from them, let me know and I get you one of the 5% off discount coupons. BTW, We aren't too far apart. LOL I'm near Pittsburgh.

Here is the exact link that should take you to the part:

Let me know your thoughts.

Hi,

Is this a GT model? I looked it up and there is a different part number.

311102V500 = GT OEM part number

31120F3500 = Other model part number

If possible, let me know the VIN so I can look it up and confirm.

Let me know.

Joe

Hi,

The OEM part number is 31120F3500. The one on Rockauto won't fit. See if you can cross-reference the number to a different manufacturer.

Let me know.

Hi,

I have missed you. LOL I hope things are getting better for you.

If you are having a rough start, it could be related to a leaking fuel injector. If the system leaks down too far, it takes a bit longer to get it running.

Try this.

1) Turn the key from off to the run position (engine off) and count to 5.

2) Turn the key to off and repeat step 1 a total of five times.

3) On the sixth time, see if it starts normally.

Try that and let me know what you find.

Hi,

If the fuel leaks out when you are refueling, either the tank is leaking or the filler tube. Have you gotten under the vehicle to check for evidence of where the leak originated?

Also, if it starts easier when you cycle the key, then we either have a weak fuel pump or there is something allowing pressure to drop off. For example, if a fuel injector leaks, you will lose all pressure in the system when the pump is off. If the leak you found is related to the fuel supply line, the same thing can happen.

We need to first locate the leak to determine the source. Once we do that, it will need to be repaired. If the repair doesn't resolve the issue, then a fuel pressure leak-down test will be needed. However, we will cross that bridge if and when we need to.

Let me know.

The codes indicate an EVAP leak. What needs to be done is a smoke test. Basically, smoke is injected into the EVAP system at a very low pressure. If there is a leak, the smoke will come out at that point.

There is a chance something was disconnected when the pump was done.

Keep in mind, since the codes are related to an EVAP leak, you shouldn't see fuel. Instead, the fuel vapors are what are leaking. Check around the EVAP canister. See pic below

Let me know.
