Replying to: obyone (Oct 26, 2008 5:59 pm) Hey Jedi Master!! Where is the fuel pressure regulator? Do you know where the crankshaft position sensor Is? My truck won't start until the second or third turn over..it used to start right away. It runs fine when it is started. Could those two things be my problem? Thank you

If you have a buddy help lift the bed at the wheel wells you can put the front part of the bed on the tire and the rear part of the bed on the bumper, also remove the tailgate, ground strap, unplug the tail light wires and fuel fill neck. It's really nice when the tank is full (lol).

Replying to: yank1 (Jan 19, 2009 2:34 pm) No I did not get a reply. It seems to be clear though; after the temps came up it retains battery charge and starts normally. I guess it is a problem with cold weather. I put a pan heater on it and will use that whenever it gets cold, and maybe a battery blanket will help too. Most frustrating, I have been driving the truck for the last few days with absolutely no problems and it is a pleasure. I like my truck. Now watch me regret saying that...
#115 of 193 2000 Chev Silverado 4x4 starting issues by grydsuk Jan 25, 2009 (5:01 pm)
Hi, here's my problem. My father owns a 2000 silverado pickup. The truck only has 70,000 kms. Whenever the temp is hits below -20 the truck will not start. It turns over just fine but just won't start. He's had the fuel pump changed and a new battery put in, and still won't start. As soon as the temp goes above -20 the truck starts no problem and runs perfect. He has brought it to several mechanics who can't seem to figure out what is wrong with it. The latest thing he is trying is injector cleaner, but I can't see this being the problem because the truck runs fine in warmer weather and starts with no problems. I would appreciate any info anyone can give me on this issue. Thanks in advance. Replies to this message: boofhead (Jan 26, 2009 8:13 am) grydsuk (Jan 26, 2009 4:02 pm) jogunde (Jan 26, 2009 6:56 pm)

Replying to: grydsuk (Jan 25, 2009 5:01 pm) I was told the problem with my truck was the starter motor. At the cold temps it takes more energy to turn the engine over and if the starter motor is not near perfect it cannot manage it, the battery goes down and no start. I bought the starter motor but the temperatures came up and I currently have no problem. Sent the starter back, it cost close to $200 and I am looking for a cheaper one before I spend the time working on the truck in the cold (it is still below freezing here).

Replying to: boofhead (Jan 26, 2009 8:13 am) The starter seems to be working fine. The truck turns over like it was summer, the only thing is, it does not fire up. It almost seems as though it's not receiving enough fuel to start it, but this is only once the temp has hit below -20. I don't get it.

Replying to: boofhead (Jan 26, 2009 8:13 am) You are absolutely correct. I originally thought it was the security system because when I turned the key only the dashboard lights came on, not the engine. I finally had it towed to the dealer and they replaced my starter assembly. It was costly, a few hundred dollars, however, I have no more problems.
#119 of 193 Crankshaft Positioning sensor help for 2002 GMC Sierra by Twztd1 Jan 29, 2009 (2:10 pm)
I have a 2002 GMC Sierra 4.3L 2WD. I am currently having trouble installing a new Crankshaft position sensor. I've replaced the old sensor with a new one I picked up at O'Reillys. It is cranking but my truck won't start. Am I missing something? Do I need to do anything aside from just a swap out on the part?   Any info would be greatly appreciated.
#120 of 193 2000 chev silverado 4x4 by grydsuk Feb 01, 2009 (4:35 am)
Well, injector cleaners did not solve the starting problem. Now I have no idea where to start. Would anyone have any clue on what to check on. My father has just purchased a Toyota Tundra and has given the Chev to me. Now it's my problem to figure out! DOH!
