#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.

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!
#121 of 193 2004 Chevrolet Silverado 3500 w/6.6 diesel starting problem by jcrichmond Feb 05, 2009 (7:56 am)
Hello, My batteries went dead and I attempted to jump start with a power pack and had no success. Engine would not even turn over. I bought two new batteries and installed them. Now the engine cranks great, but engine will not start. Is there possibly a lockout that could have operated that is preventing the engine from getting fuel? I read in my owner's manual about "PASSLOCK", but it does not give me any information on how to reset it, and it states that it only operates if one tampers with the ignition or is attempting to start with incorrect key. I bled the fuel filter looking for air, but good fuel came out the top bleede screw opening immediately, so I don't understand WHY i am not getting fuel, if that is, in fact, the case. Thanks for any information/advice offered. jcrichmond
#122 of 193 SMOG FAILURE by chAIRFORCE Feb 15, 2009 (9:44 pm)
Hey Yall!   Im stationed out in Cali and have to have my 2001 silverado smoged to get it on base, so I failed the first time and took it to a shop and they cleaned off some dirt and mud on my EVAP system and got my check engien light to turn off. But they re-set my system by DCing my battery, now i cant get my Evap, Cat and EGR monitors to run so i cant even smog it. The Machanic wants to replace my fule pump, he said it will help get those systems to run. But I wanted to know if anyone knew how to get those systems to run ie. "5 mins at 35mph" or "12mins at 125mph?" or whatever. gettin frustrated thanks and stay classy!
#123 of 193 Problems with 2006 Silverado Starting by lucas44 Mar 13, 2009 (10:34 pm)
Hi folks,   I am posting this on behalf of my dad who purchased a 2006 GM, diesel truck with Duramax engine. It is a 3/4 ton Silverado. They use it to haul their fifth wheel. About 6 months ago it would not start on 2 occasions.The first time apparently there was a problem with "the relay" which was fixed, and the second time a computer part was replaced for around 2k, no cost to them as under warranty. My dad was concerned as he had had the truck only for a few months at that time. They recently returned home from a trip and the truck is again not starting, so just wondering if anyone else is having problems. The truck had been sitting for about 2 weeks,cold weather is not a factor. The truck was in the garage this Tuesday and they have yet to find the problem. Just wondering what you guys think the problem might be. My parents are retired and this truck was to last them for their "travelling" years. Thanks!!
#124 of 193 95 GMC Sierra 1500 STARTER PROBLEM by donparadowski Mar 28, 2009 (5:49 pm)
I am bringing out of long-term storage a Jimmy with a 4.3 L V-6. My problem is it won't turn over much less start. The battery was useless so I replaced it and the starter with a rebuilt gear reduction starter because the old one had a diagnosed bad Bendix drive. So, we need not address those issues unless someone wants to suggest that the gear redo starter is bad from the rebuild shop. I purchased from a reputable rebuilder that I have been doing business with for years so if it is in fact bad, human error simply showed its ugly head.   I would appreciate some incites to this problem. I used a magnetic induction amp meter on the rebuilt unit in the truck and it maxes out the meter at around 85 amps. Unfortunately, I do not have one that goes any higher to use. The ground is connected to an exhaust manifold stud. It is quite thick in good condition and tight. The battery terminals are also clean and tight. I DID NOTICE that there seems to be a small ground cable that looks like it goes from the body to a bell housing bolt is disconnected.   I can be reached directly at donparadowskiyahoo.com. Thanks.
