I have followed my manual to the letter (I think). I set piston at TDC on compression stroke. Lined up indent with white mark on lower distributer shaft, and set distributer back in. Truck wont start for anything! I have tried this about 9 times and had no luck. Before I attempted this, the truck was running great but throwing the P1345 code. I originally had to pull distributer to replace intake gasket.

Seem as if the manual is not correct on how to set the timing. You cant follow the diagram. Go TDC compression stroke on number one. Set rotor button so it points to number one wire on distributer cap. Engine is now in time with no codes popping up!

You have to set up base timing on that engine...I believe you have to pull a plug. If you time it without pulling the timing bypass your are uber retarded.

Full timing on your truck is about 27* at idle and 37* @2200 rpm

Base timing is about 8* BTDC...so if you set it up without the bypass unhooked you are off.

 

I'm not 100% sure on this year of truck if its the light brown wire that goes into the black box on the firewall on the passenger side though.

Nytemare, I have no idea what you are referring to. Like I said, pulled number 1 plug so we could find TDC on compression stroke, pulled distributer, lined up rotor button to #1 wire. plugged everything back up and it runs great with no service engine codes.

That is for 95 and older TBI trucks. 96 and newer vortecs you use a scanner to set timing.

yeah, that's what I started thinking after....I knew it was for anything pre OBDII, wasn't sure if the Vortec 350's held on to the base timing routine all the way up to when they were phased out.

      Looking at ordering a '26 WT because I want a std cab, std bed

      By newdude · Posted

      So.  Get this.  On the Chevy regular cab, you can get the factory remote start at the dealer from the accessories catalog.  BUT.  GMC, you can't.   Now...get this...GMC 2 door, you CAN get the power seat.     Go.  Figure.   Anywho.  are you trying to order?  Or locate?  Ordering for 2 door 1/2 tons has been stopped as of April or May?  So you won't be able to order.  You'll have to shop on the ground units or in transit units.     Ordering was stopped because the new trucks are coming.

      Tonneau cover that does not leak water

      By cherryred21duramax · Posted

      Thank you.  I really appreciate the well wishes.  I'm an engineer in the telecom industry, I know hardly anything about marketing.  Over the years I did some videos for nonprofits and web sites for small businesses and the seed was planted.  Agree with over-buying, I started shooting on an iPhone before I got my first DSLR and tripod.   I'm looking at trucks with potentially 150,000+ miles to keep the cost of entry low while focusing on the client experience and equipment.  Good wireless mics for interviews, the right lenses & lighting to look professional.  But I don't want to be late or break down, the stress of emptying a trailer & securing a rental truck right before a gig would negate any savings from buying a junker.  So anything that leaks water, has extensive rust, or generally unreliable I'd like to avoid.   Does GM/Chevy overbuild these trucks for upfitting?  I talked to a local upfitter, they sometimes tie lights & other 12V into existing circuits, which I always thought was bad.  Which is why I enjoyed the AUX upfit switches on previous trucks (odd they mostly come with off-road or work truck packages).

      GM's are stainless and have a fairly robust powder coating, although, still not worth $850 in my opinion. They will hold up a lot better than their cheaper steel aftermarket counterparts.   What I like about the GM step bars is dealers will often equip their dealer stock with them. Lots of margin. Which means a lot of people end up buying them because they're already on the truck, even if they don't like them. So it's pretty easy to find brand new takeoffs with hardware on Marketplace and Craigslist for about $250.   That's what I did for my crew cab. I wanted ZR2 rock rails for the look, but with the ability to bolt up GM's assist step package. From GM it's about a $2500 accessory all in. The old folks in my life can't get in the truck without steps. I found the whole package on marketplace for $180.

      Forward collision and lane keep assist still a problem on 2022 refresh?

      By kr477 · Posted

      I am really glad I found this post and this site... We have a 2022 1500 refresh LTZ that has these problems: - forward collision avoidance warning light - lane keep assist unavailable - adaptive cruise control unavailable   The truck was bought as a new leftover in 2023, so it was still under the 3/36 B to B when it went in for these problems earlier this year. It has been at the dealer on and off now for about 110 days now. These are some of the things they have done that I can read on the service tickets. - replace/add ground straps (4) - check all battery cables and vlts - replace serial data gateway module - replace front view camera - numerous reprogramming - a few calibrations (apparently ending with 'learned') Last week when I had it back the truck had those 3 warnings every time we used it except for 3 times. On three separate occasions the truck started and ran perfectly with no (zero) warning messages or warning lights lit - everything worked perfectly. Over that same time period the truck did not work on every other 'key' cycle which I would estimate at 60+ cycles. On those estimated 57 cycles it had the same 3 problems each and every time.   It is back at the dealer now - can anyone help at all with what the true problem might be?  Or possibly what can be ruled out leaving a lower number of possibilities? Thank you very much for any help you may be able to supply....
