I have a 2000 gmc g2500 5.7 cargo van. The van wont start but has spark and fuel ! I have been cranking it since 8am and the engine wont fire at all. I tried to get it to fire by spraying starting fluid in the air intake and nothing happened at all. With starting fluid i would at least hear some sort of firing but i get nothing. I replace the coil and control mod and still nothing. Does anyone have aby ideas of what could be the issue. Thank you very much !!!!

 

 

I just noticed that i have a code 1351 its a preliminary code, did not set the light.

 

Also i noticed that the spark is more orange than blue or white.

Hey, when was the last time you looked at/or changed spark plugs? Those things can oil up bad and won't work. Happened on my 2006 silvy last summer!

Check your cap and rotor to see if they are corroded. Also if you could get a fuel pressure reading.

Just came to me. I had one like this a couple of weeks ago and it turned out to be the dist shaft was broken causing the rotor not to spin. Easy way to check is to take the dist cap off and see if you can turn the rotor if you can turn the rotor while the dist is still in the motor your shaft is cracked. good luck

the rotor spins. the weak orange spark is coming from the coil. i replaced the coil and the ign mod.

Dude are you posting 1\3 of your problem on different threads because that's going to get you 1\3 of the answer you need. You need to compile all that you did and all you found and repost in one place otherwise we can't really help.

I didnt mean to make a mess with the posts. Is there a way i can combine them so i can close the treads on the other 2 ? Everything i have done on the vechicle was done before the post and nothing worked. I think it is in the wiring.

I don't know if there is a way to combine the posts. Try to make one new big post with everything you know, vehicle, engine, problem, codes and anything you did or noticed. There is no way to close a post here (I don't think, mods can lock them but they don't for this). Just start over so were not chacing threads all over.

 

note "It's in the wiring" There is almost as much wire as metal on a modern vehicle that doesn't make it easy.

 

If you repost with everything you know in one post it can help.

      Wiring Help, Please

      Thanks; I looked there a few minutes, and I think I can find something. I really never looked there, as I thought it was stuff like PTO/aftermarket bodies/accessories like snow plows.

      2 speed transfer case optional now?

      By newdude · Posted

      This is a 1/2 ton thing ONLY.  All HDs 2020-2026 have the two speed transfer case, with Autotrac as an option.     1/2 tons 2019-2026, regular 4x4s come with a single speed case (no 4LO!), and trucks with Z71 ordered, or all Trail Boss trucks come with the 2 speed case.  2 speed case is also an option on WT, and is also standard on High Country.

      Different requirements for oil filters?

      By newdude · Posted

      2013 5.3 still to this day calls for the PF48 filter.  Which as a 15psi bypass pressure.     There is a TSB, 17-NA-157 that talks about the PF-63 and PF-64 filters which have a higher bypass rating of 22psi.    TSB HERE - temp.xml   "Beginning in 2012, the oil pumps began to regulate main gallery feedback instead of pump out pressure. This means that the oil pump now does not begin to regulate until pressure is built up to the main gallery. This change reduces the amount of time it takes to provide oil to the engine bearing and lifters during extreme cold start conditions.  Main gallery feedback oil pump control systems are present on the following engine families which use Spin-on oil filters: Small Gas Engine (SGE), Large Gas Engine (LGE), High Feature (HFV6) Gen2 and Small Block Gen5 gasoline engines. These engines with the main gallery feedback oil pump control systems are factory built with an ACDelco® oil filters"   It also calls out what engines use those filters.  The gen 4 small blocks were not on that list (LMG, LC9, L9H, L92, L94, L20, L96).  Gen 5 small blocks use the higher pressure filter.          That all said...   Your 7045 Napa filter is the PF63 equivalent, with 22psi bypass.  You are already using the higher bypass pressure filter.  You CAN keep using it, you don't technically have to use it though.

      Different requirements for oil filters?

      By Grumpy Bear · Posted

      Do you know WHY the filter relief setting was increased to 22 psig?    When the new system goes into the second stage the pump volume ramps up considerably. It was found that the 15 psi filter bypass setting put the filter in bypass on a warm engine when the second stage was activated. Raising the filter bypass setting forced the filter to do what it designed to do. Filter. Preventing debris from circulating during high load, high rpm operation.    So next question is how did GM find this out? VLOM/lifter failures and a deep dive by Melling Corp.    Last question. Is it required? Look at it like this; a motor may be equipped with a rev limiter. But it only works if the set point in reached. That 22 psig setting only matters if the pressure differential across the filter media exceeds 15 psig during normal warm operation. Second stage kicks in around 3000-3500 rpm.    I can't answer your question because I don't know you and how you use the truck. But I think there is enough information here to let you decide for yourself. 😉
