Distributor/coil wiring

A friend of mine has a 90 or 91 1500 with a 350. He has just had the engine rebuilt and not been able to get it to start. He needs the wiring schematic/drawing showing the coil to dist to harness details. He has a new coil and a new dist but cannot figure how to hook them up. So far, he can get no spark out of the dist.

I'm asking for him 'cause he does not have internet service.

Thanks

MoJo, I'll try to look it up in my Chilton's tonight. Also, is he sure his ignition coil is outputing? I used an old spark plug wire to connect to the coil and then connected it to a calibrated spark checker to ensure that the coil is in fact putting out voltage to the distributor.

MoJo,

 

I'm going to ASSUME that the truck in question has High Energy Ignition System and that it does NOT have the Iginition Coil in the distributor cap.

 

The coil output is the round post connector on the top of the coil and connects to the center post on the distributor. The left most 2 pin connector is for the battery terminal and the right most 2 pin connector is for tachometer and coil terminal connection.

 

On the HEI Distributor body, there are 2 lower connectors, the left most is the ignition coil connector terminal, the right most is the Four Terminal Connector. On top of the Distributor cap, the center post connects to the ignition coil. The firing order is 1-8-4-3-6-5-7-2 clockwise with 1-8 facing the grill and 6-5 facing the firewall.

 

Hope that helps!

      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.

      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. 😉

      2020 Trailboss 6.2 replacement

      By newdude · Posted

      Probably not their first rodeo, so it should go as planned most likely.  Typically the service manager or tech doing the swap will put some seat time to shake it down after they get it all put back together.  We usually put 50-100mi before we hand them back so if something happens, its not after you get it.  A coolant leaks, oil leaks, a ground left off or loose, vibration, etc.     The new engines so far have been good?  There's been a couple that have popped out there again (the replacement engine) but most have been okay.
