Anyone having problems with their Fuel Pressure Regulators on a 99 Silverado? I was told by a mechanic that if fuel is inside, that its bad and needs to be replaced. Just looking for some input before I spend 60 bucks (I was quoted somewhere around 50 - 60) for this little what looks like simplistic piece. When I go to start my truck, after its been sitting awhile, every 3 or 4 times of starting I have to pump the hell of out of it to get it started. The other times, once it fires, it idles at like 500 rpm and I have to give it some gas to keep it running. Any other ideas would be greatly appreciated. I'm fairly new to the gearhead world so I wouldnt exactly call myself a master mechanic :jester:

If you pull the line of at the regulator and smell gas real bad or see gas thr regulator is deffinately bad. Had to replace one on my old 99 before trading. I pulled the line off and gas poured out the reg. Be sure you get the old oring out before installing the new reg.

Thanks for the info. I pulled the line off and gas poured out. A mechanic friend told me it was bad so I guess I will have to replace it. Any difficulties when you switched it out? I see theres a metal clip type thing that seems to be holding it in place. I didn't want to start prying on it or anything until I found out for sure.

Thanks for all the help. Got one for no charge from a mechanic friend and put it in. I thought perhaps it might have been under pressure and wasn't sure if it would be wise to remove it without knowing for sure. Trucks running good so far. Hopefully this cures the problem.

Where is the pressure regulator.  Mine might be bad I have simular problem intermitinly

It's in the middle of the fuel rail, on the intake manifold, on the driver's side, held in by a clip, with a vacuum line attached to the top of it. Pull that line and check for fuel. :puke:

I have an 01 4.3 v6. Is the regulator in a different place on my motor

Not sure exactly where it is, but it should be on the fuel rail somewhere. Anybody else have a 4.3 here?

      The amount of storage in the rear seat area is huge. You can keep all your cycle gear dry and clean back there

      Subtle vibration, can of worms opened.

      Truck in fluid changes and investigate subtle shudder at cruising speeds.  Told them it felt like my ‘14’s shudder when AFM kicked in.   Dealer #1 :  You need a new torque converter.   6 weeks later, after causing other damages to my truck, I get the truck back.  Same shudder exists. New, more violent shifts and vibrations at low speed.  After choice words and a few more weeks of waiting for them to replace my running boards supports, I move on to another Dealer.   Dealer #2:  The cruising speed shudder is DFM.  (I didn’t realize truck had it.) The TCM/ECM needs updates.  Updates will solve all vibration issues.   They perform updates, truck seemed ok in lot.  Not a mile down the road, SERVICE BRAKE PAD MONITOR. Dealer #1 stated brakes were at 4mm.   took truck back to Dealer #2, rear brakes at 2mm and less than 1mm.     New pads/rotors on rear, new pads up front.   truck seems good. Toggle through menus, brake monitor system is disabled.  Huh?  Why? Turn that sucker on : SERVICE BRAKE SYSTEM!     will not reset manually, automatically, or even after pulling negative bat cable for 30min.     Could the TCM/ECM updates the culprit?    A torque converter diagnosis for a “normal” shudder and now I’m thousands in the hole and the truck still isn’t right!  Beyond pissed.

      Seats matter a lot.  I would start there - good advise here.  I had a 2018 LT Colorado before my 2026 LT Silverado, and the seats are so much better in the new one it's not even a contest.  That was one thing I always hated about the Colorado and I owned two of them spanning 10 years - but I did it so I could park in the garage mainly.  Now I have a much larger property and a huge barn so I have plenty of parking options and a full size is more useful for maintaining the property and current hobbies as well.  I wasn't evenb thinking about the seats as part of the reason for the move to the Silverado, but after two back to back 700mile road trips I am sold on the LT seats w/ leather 100%.  The other LT features are also nice - one thing I really like is the power rear window on the back window by the bed.  And the lighting in the bed is also very nice to have - I doubt that comes on the lower models.  Power tailgate - also quite useful - it's a heavy slug!  What else - I could take or leave the screen - but heated seats and steering wheel and cruise control on the steering wheel is very useable - I would never want to live without that.  Even the colorados had that.

      I think the ship has sailed on the fuel injection type - everything is getting direct now.  Does it help with mpg?  Not really and nobody buying a HD truck really cares anyway.  But that is what it is at this point.  Piston rings is something they may well adjust over time to get them right.
