Ok i asked this awhile back, I still takes my truck about 10-15 to start my truck when you let it sit awhile? i replaced the fuel filter and checked the vaccum line on the regulator for leaking fuel, but found none, spark plugs didn't make a difference either. Whats wrong? I cannot figure this out and i don't want to take it to the dealership! help me guys

 

well did this start after the tune? not trying to start anything. Have you ever had the injectors cleaned?? have you cleaned the T/B blade path?? later kevin

 

Okay it did the exact same thing before the westers tune, i have cleaned the TB myself real good, but never messed with the injectors.

 

like v8 said get the injectors cleaned. i had mine done and it made a bigg difference. it cost 100.00 don here.

 

can you hear the fuel pump when you first turn the key on?

 

Have you tried replaceing the Fuel Pressure Regulator?

 

Where is the fuel pressure regulator?

 

Driver side fuel rail, gold in color should have a vacume line going to it.

 

I had similar problem with my 99 when I'd let it sit. I put an Optima red-top battery in it. I noticed that even when I let it sit for 2 weeks, it would fire up right-away when I turned the key. I don't know if this helps any!?

 

I can hear the fuel pump when i turn the key to the on position. Now on the regulator, should i really replace it? I noticed that it has a filter in it, could it be clogged or something?
