#1473 of 1492 Intermittent no start problem 96 Sierra by odqlesz Sep 13, 2006 (3:39 pm)
I have a 96 Sierra 1500 4x4 5.7 Once in a while(about every 2 weeks) I have the following starting issue. It starts fine, but once I go about 2 feet it dies. I try to start it again, but no juice. It seems like there is a short somewhere. I can turn the key to the on(not crank) position and the lights on the dash flicker, the speedometer goes up to 30mph and I hear a buzzing noise under the dash that sounds like when you have your door open(but it's not that buzz). If I try to crank, nothing. It doesn't even turn over. After playing with it for about 10 minutes it will start again. I will try everything. Fiddling with the connectors, shifting gears, pushing break pedal. I don't know what exactly I did, but eventually it works again. Sometimes it stalls right back out after going two feet other times it's fine. It happens intermittently, sometimes in the morning or after I've been driving for a while and stop somewhere and turn the engine off. After I get past the first two feet, it will not happen, this only happens in the first two feet.   Example: one time I pushed the brake pedal a few times an shifted the gears then it worked. Last time I tried everything but it seemed like nothing worked. So I pushed the horn button to see if it would work and it did, then it started fine.   One time after this the radio died.(turn it on, no lights, no stations, the casette wouldn't even go in, just hear static if i turn the volume all the way up) I thought maybe it got shorted out. I checked the fuses, all ok. Then recently I had the starting problem again. When I finally got it started, the radio works fine.   The battery is newer, connections are good. Newer alternator(this happened before the alternator was replaced too). All fuses seem to be good.   Any suggestions?

#1474 of 1492 Towing with 2005 Sierra 1500 by ynotps Sep 14, 2006 (11:42 am)
I have an 05 Sierra 1500 5.3 V8 with the towing package, bought used recently with 18,000 miles. I didn't get the owners manual. Does anyone know if this truck can handle towing a trailer rated at 6000 GVWR, or will it be too much of a strain on it? Thanks for any info!

Replying to: ynotps (Sep 14, 2006 11:42 am) In my opinion, 6000 lbs is the practical towing limit for a 1500 truck equipped with either 3.73 or 4.10 rear end gears. With 3.42 gears I would not exceed 5,000 lbs. With 3.23, 4000 lbs.
#1476 of 1492 '98 Silverado Tranmission Problem by ltw12000 Sep 15, 2006 (5:28 am)
Has anybody ever had their transmission rebuilt and then have the truck keep shifting out of overdrive and act sluggish?

Replying to: ynotps (Sep 14, 2006 11:42 am) Your truck with the standard 3.42 gearing is rated for 7000lbs, with optional 3.73 gearing, 8000lbs.   I've got the 3.73 and regularly tow 6000lbs without any problems. A little slow on the uphills, but it doesn't seem to be too much of a strain at all. The 5.3 is a great engine.   Just be sure your trailer brakes are working. The real strain happens if you try stopping the 6000lbs without them.

Replying to: ynotps (Sep 14, 2006 11:42 am) I just bought a 2006 Crew Cab 4x4 1500 with the 4.8 motor and the manual lists my truck w/the 3.42 gears as being able to tow 6,700lbs. U-haul installed a class 3 hitch capable of 6,000lbs. Oh well, my boat only 2100 lbs so I'm not too worried.

Replying to: raiderken (Jul 15, 2006 7:28 am) If the tires have been changed or the axle ratio changed then the computer can be reprogrammed to correct for this. You need to know if the odometer is correct also when you go to get it reset.

Replying to: albird1 (Sep 10, 2006 7:59 pm) Sounds like it might be antilock brakes. It is located near that area.

Replying to: raiderken (Jul 15, 2006 7:28 am) I can retune with my TunerCat programmer.

Replying to: odqlesz (Sep 13, 2006 3:39 pm) my truck had the same problems it was the positive post had a loose inside the battery move the cable it would start. try another battery and clean the cables good at any rate i think your problem is in the battery or cables not getting good connection. I know you have already done this, but try it again might be suprized.                            bobby Replies to this message: wolfsroad68 (Sep 24, 2006 6:38 pm) brp1 (Sep 25, 2006 7:38 am)
