The protocol is called the fuel pump is probably weak. Try putting it in RUN for a few seconds before starting it. If that helps then the fuel pump needs to be replaced.

 

Sorry for slow reply but it started right up after turning to run, but hesitating to crank for a few seconds. How critical is fuel pump replacement given it runs fine, aside from start up? Will it continue to degrade? Not easy to answer, I bet.

 

That’s great. I’ll try that tomorrow. Thank you Tin Foil Hat!

Since you mention that colder temps may be part of the issue, have the battery load tested to rule out any issues there.
The test is free, and you'd probably not want to head into winter with a flaky battery.

Thanks Don. Battery seems fine, it cranks strong, but I’ll get it checked. Thanks for suggestion!

 

My fuel gauge is now intermittently working/not working. Is the sending unit for the gauge in the fuel pump?

 

Hi Angler:
The pump and sender are part of the same assembly. Since the tank has to be dropped, it's wise to replace everything while you are in there. We recommend oem for fuel pumps if possible. In the event you can't find one, a brand name like NAPA, Delphi, etc are better choices than Airtex, etc.

Thanks Don. I was wondering about quality of this hard to install part. I saw $50 versions on eBay and thought that was probably a bad idea. I appreciate your advice!

 

Angler:
If you go to R and R the fuel pump, check out my thread below re my search to cure the P0456 on my old 2004 SLT.
There are tips for dropping the tank.

Thank you Don.

i had the replacement pump put in by a very reasonable service garage. I bought the pump (Delphi) $175 and a new lock ring $45 which turned out to be needed. He only charged me $300. In addition to the symptoms I was experiencing, the pump was leaking gas. the mechanic said the pump sits in a little recess and the recess was full of gas. I’m so glad I got it fixed. Thanks guys!
