Hi all, Sorry for the cross post I had already posted this in the HD forum but this one seems to get a lot more action so I though I would post this here. Just bought a 96 GMC Sierra SLT 2500 ext cab, 4wd, 8ft bed, 5.7L w/towing package. Its got 200k on it and I get it cheap so it has some issues and the SES light is on. Need it for towing my race car next year.

 

1. The SES light code is P1345 I think. It showed on the code reader as "Crankshaft/Camshaft position sensor". My problem with that is, if either sensor was bad in my experience the truck either wouldn't run or would run like crap, however it purrs like a kitten and runs great. Wasn't about to spend $80+ on 2 sensors so I want to hook it up to a better computer to see what the real problem is. Any ideas? Am I possibly just wrong?

 

2. That said when the truck has been driven for a little while the oil pressure is at 0 when I'm stopped at a light. I feel like the sensor may be wrong, as i said, runs great, plenty of oil, no noise at all. Pressure gets up over 20 at 2k rpm, and continues to rise.

 

3. Brakes are strange. They work great except for the last like 2 mph when youre coming to a stop the ABS activates and it seems to pull to the right. My friend said it may be the rear drums however unfortunately the wheel was stuck on so we just hosed it down with PB blaster and are letting it sit for a bit.

 

4. When the headlights are off the Green brights indicator is on on the dash, then if I turn them on it goes off. Is that supposed to be like that? The brights and headlights function properly.

 

5. Any cheap place to source the factory style leather seat covers (or cloth even) and instructions on replacing them myself? I know its brave to try but I don't want to spend a lot to have an upholstery shop re do the seats. I have the 2 bucket seats with single armrests.

 

 

Thanks all.

I'll take a swipe at number 4.

Assuming you have DRLs, the green "brights" indicator is in fact your DRL indicator. (Daytime Running Lights) It lets you know that your DRL's are on so you don't forget to turn on your driving lights at night.

Enjoy the truck!

As mentioned above, #4 is correct, this is how they work. My '97 is a 5-spd, and so I learned a little known fact: If you put your parking brake on, the DRL's turn off.

 

When I bought my 2011, the dealer said that "After so many complaints, GM finally switched it so you can turn the DRLs off at the switch. Before, when you were watching a christmas light show, you had to turn the car off and get cold or everyone would get mad because your lights were on".

 

Not so, the e-brake shuts 'em off. At least that is how it is on my truck. Those with autos probably never knew as they probably rarely ever used the ebrake.

 

As for the other stuff, I can't really help you at the moment. My brakes are fantastic, but then again the ABS light is "ON". :thumbs:

Strangely enough the truck has no DRLs, or they don't work. But the light on the dash is on lol. Thats what confused me, as of course I have another car with DRLs that that light is on. But unless they are broken its just weird. Heck based on the rest of my post its the least of my worries.

 

I would love to go no ABS, but I would never pass NY state inspection. :thumbs:

      Intermittent no-code issues on 2022.5+ V8 trucks — what did the shop fail to capture?

      By asilverblazer · Posted

      Length/amount of data capture will be important to consider, sifting through 5 minutes of a data log can be enormous when it is stored in milliseconds. Being able to find the 'event' let alone decipher it.   Presumably the driver would notice something and hit a button to capture the 'window' of data. That window has to be large enough for the operator to recognize the event and react accordingly.    The data has to be able to be retrieved easily.   The data has to be able to be understood. Which is the biggest challenge, dealer techs won't even know what most of it is and would likely not even look at it if an owner brought it to them. Meaning the owner, the least educated/qualified, trying to understand it.    How will the data be presented? Could specific PIDs be selected and a timelapse graph be watched? How will a specific value be noted as abnormal? Additionally, a good data logger would be able to 'learn' normal values for a specific vehicle and flag abnormalities automatically. It could in theory watch parameters degrade over time and suggest maintenance as needed. (If the MAF reading begins tapering off for a given set of other readings - MAP, throttle position, Ambient, etc.. a flag to check air filter.) With the amount of data available, a device (really the vehicle rather than an additional accessory) should be able to do more than issue a DTC. It should be able to run the full diagnostic suite automatically and present a solution rather than a code. (It's not the 90's anymore). The technology is available for the vehicle to not just say "P0087", it should know low fuel pressure, check other PIDs to narrow down the problem itself, and determine if it is a lift pump, high pressure pump, regulator, leak in the fuel line, clogged filter, etc. Even if it can't narrow it down, it should be able to guide the user to the likely problems.   This would be a major problem for dealer service departments, which are the manufacturers customers it is in their collective best interest to NOT have this available to the consumer.   Further, if the owner is going to be the primary consumer of the data, it's got to be at a consumer price point vs. dealer only specialty tool price.   This group is more 'involved' in their vehicle than general public/consumer and will have knowledge, experience, needs and desires that are quite different from the market at large.

      I put the prof up. If you read what I posted. You can see that housing, cars and income are in line with the era we were talking about. It’s harder in some places easier in others. Let’s agree to disagree and put this back on track, OK? We both are pretty stubborn and hard headed. But I bring receipts. If you wish I will not respond to you in the future.

      Lets see if I can sum up two pages of nothing useful.    You want to refute your own governments data of the "Purchasing Power" Index FOR THE ENTIRE USA and its territories replacing it with the experience of a single family and its business and label that reality?  Then pound on that for a week hoping it will find traction?    Stan, I've told you several times. I don't do irrational. There are more people in the USA than your family.    I'm pretty sure this tread is so blown up. I'll give you a few days or months if need be to post yourself silent then I'll see if I can find enough parts of the train to reassemble it.

      VSE CCV Bypass - Anyone have this installed in their L5P?

      By asilverblazer · Posted

      Facebook groups hate VSE, poor customer service; their responses to criticisms are pretty poor for a reputable company. I'm not a customer, haven't bought anything from them, but how they handle themselves on social media is a definite "No" for me.
