#108 of 193 Re: 2004 Silverado 5.3 [Distilled] by Distilled Dec 30, 2008 (10:39 am)
Replying to: Distilled (Dec 26, 2008 4:06 pm) **UPDATE**   Short version: Connectors at the PCM were checked and corrosion and water was found, the connections were cleaned, greased, and reinstalled and she fired right up. I got the truck back last night, the only pending problem I've noticed is that the XM radio, which was factory installed, does not come up as an option on the radio. Other than that it's running like top.

Replying to: chevyhauler (Dec 28, 2008 1:29 am) What exactly has voltage? If you have voltage to the solenoid and to the starter when the key is turned, and assuming some force field isn't interfering with the case grounding of the starter, I'd say you got a bunk starter or at least a bunk solenoid on the starter.   If you don't have voltage at the starter motor or solenoid have you checked the obvious items such as fuses/circuit breakers?
#110 of 193 Sierra starting problem by boofhead Jan 08, 2009 (9:26 am)
Normally '95 truck starts and runs fine. Have had temps of minus 20 for 10 days and it is affecting everything, including my ability to remain outside working on the truck! Three batteries in 3 months. Charge battery, lights shine bright. Turn switch to ON and voltage only indicates 8. Turn switch to START and lights dim a little, solenoid clicks half-heartedly and starter will not turn. Put a jumper on and no change. Still will not start. When switch ON volts are only 8. Put an amp meter on the ground line with ignition switch off and there is a residual 0.8 amp drain on the battery. I usually disconnect the ground line from the battery overnight to protect the charge for the next morning. Have not been able to find the source of the ground leak (pulled all fuses, relays etc and still a constant drain). Sometimes if I leave the charger attached for 10 minutes, it starts up OK. While running the volts indicate 15-16 initially, then settle to 14 when battery is fully charged. If I start within an hour after shutting down it works, but if I leave it more than 2 hours it is dead. All indications of a good battery (lights bright) until I turn on the switch. Maybe the temperature stops the voltage from reading right? I suspect the starter is faulty, taking power but not turning over, but if the volts are reading right, why does the volts read only 8 when the ignition switch is on? If it was really 8, the lights would be dim? If it is the starter, would not the volts drop only when I turn the switch to START?

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

Replying to: chrisgh (Dec 26, 2008 3:16 pm) This may be common knowledge but I have found it easier to remove the bed while changing a fuel pump. I have done this for years. 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: boofhead (Jan 08, 2009 9:26 am) I am new to this and did not see an answer to your question. I have the same problem. Did you get an anwwer and/or get it resolved? thanks. Replies to this message: boofhead (Jan 19, 2009 7:23 pm)

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.
