My 2000 Silverado 2500 w/6.0 sometimes has no power.Does not matter hot or cold,always starts and idles fine.Go to accelerate and will not pick up RPM.If you hold pedal steady eventually power comes back.Then will not act up until shut off again.Like I said doesn't happen all the time.Replaced fuel filter,checked fuel pressure55psi,new air filter,spark plugs the whole gammet.Cleaned MAF sensor.Anyone else with the problem and what did it take to fix.

Replying to: wildcard00 (Nov 13, 2009 8:36 pm) Sounds like a problem with your throttle position sensor Replies to this message: wildcard00 (Nov 14, 2009 7:47 am)

Replying to: obyone (Nov 13, 2009 8:52 pm) Thanks for the quick response.Would that not trigger a check engine light?I plugged my Scan Guage in and no codes found.The TPS seems to be reading correctly which I can monitor with the Scan Guage.The degrees move with opening and closing of throttle.

Replying to: wildcard00 (Nov 13, 2009 8:36 pm) fuel pressure regulator? easy to check, pull the vac hose off the regulator see if it has fuel in it Replies to this message: tiannaj (Nov 21, 2009 4:26 pm) bruce48532 (Nov 22, 2009 5:32 am) bruce48532 (Nov 22, 2009 6:30 am)
#317 of 336 non-manufacture fuel pump by tiannaj Nov 21, 2009 (3:47 pm)
I have a 2003 chevy silverado 1500 and its attemting to start, but sputters & dies out. I got a new fuel pump less than a year ago. It is a non manufacture pump & was pricey. First I replaced the fuel filter, that worked.Then we put a new starter in (that wasnt the problem).After that I replaced the crank shaft censor; that worked for a few days. Then It did the same thing. I had it towed to a shop; they just replaced a fuse & it started and I drove it. The next day it wouldnt start again. The truck attepts to but sputters out & dies. I just am not sure what else it could be. Any ideas? Thank you, Tianna ?

Replying to: bruce48532 (Nov 14, 2009 11:20 am) hello, where is the regulator located? thanks again Replies to this message: bruce48532 (Nov 22, 2009 5:32 am) bruce48532 (Nov 22, 2009 6:30 am)

Replying to: tiannaj (Nov 21, 2009 4:26 pm) up by the throttel body driver side, there is a small 3/16 dia. rubber vacuum hose connected to it. If you pull the hose and it has fuel in it the vacuum hose the regulator is bad.   I think the cost is about $30 and take only a few minutes to change   i can send a pic, email me tdebatyahoo.com
