I installed a new Napa fuel pump in my 2000 last summer. It's been starting quickly and normally until recently. Now it takes a few seconds longer of cranking before it starts after sitting for a long time like overnight. Before I do any pressure testing (too cold for me) or key-on priming before starting (always forget), I'm figuring it's the fuel pump allowing drain back. Thoughts? Opinions of Napa (Airtex I believe in this case) fuel pumps? Does it sound like symptoms of something else?

It's supposed to be warmer this weekend so I can diagnose.

Thanks

 

agreed...I prolly test the fuel pressure 1st...& make sure its still up to snuff.

might be a fuel pressure regulator??

air filter been replaced?? has the MAF sensor been cleaned? shuckes how about the fuel filter?

Load test your battery yet?
