    81 K10 fuse panel layout

    there is not a fuel pressure sensor in a late 90s early 2000s Gen 3 LS If you have throttle cable and EGR, that would be early 2000s iirc The crossover line doesnt look like the first one, i dont think, but you can date it fairly easy if you just look at the ID stamp/engraving. Also a send...

    i see a purge valve and what looks like an EGR pipe in that order Im not sure what the last photo with arrows is

    3 or 4 cylinder engine with a 8 or 6 cylinder Dwell meter.

    same situation for waste spark engines iirc unless one is somehow only triggering off higher energy sparks (wasted spark on the exhuast stroke is much lower energy than the needed one), but thats more tachometer than dwell meter, for all i know.

    Ignition problems

    if the issue were to persist with turning force, decoupling the starter engagement from the key switch is a minor anti-theft thing one could do and it would benefit if you had high compression because you could also switch the ignition on/off with another switch or just the tumbler to crank the...

    DO NOT USE OIL PRESSURE GAUGE FOR FUEL PRESSURE. You need a fuel pressure gauge! Also, crawl under the truck and look at the pipes coming off the fuel tank, there should be 3 hoses. if you only see 2, then there may be a thing on the tank vent blocking the line, which would be problematic for...

    Rear Brakes Locking Up

    I dont know if the OP brakes look like this but in my research I thought these diagrams were nice and very detailed, this is a troubleshooting for brake drag from the cables which I dont think he has issues with.

    Rear Brakes Locking Up

    Yes, to my knowledge the low drags will always have plastic and the reservoir is now somewhat combined more than it was on the metal(the metal seem to share fluid above half way, or divided entirely) , the plastic ones either have a divider too or a float or something to prevent hydraulic...

    Oh.. so im confused, you want to move it or you want to have a second gauge or difference between the hot oil and returned oil?

    8 lug hub with 6 lug caliper

    Are the backing plates 2 piece in the 80s? I have a 3/4 ton 70s backing plate for a photo but its one piece, quite the large piece I remember smoething about the weight reduction efforts in the 80s had made them lighter Mind you, 1980s K5 may have come with low drag disc brakes ,which means a...

    Rear Brakes Locking Up

    True, a lot of people don't realize that the braking surfaces are left machined ready to go, and to not rust they oil and bag the drum /disc Without the machined surface and having rust, you'd have to brake a bit before being able to get your brakes adjusted to be able to set them accurately...

    Rear Brakes Locking Up

    thank you for the measured and meaningful push back, I posted my reply before seeing yours. I do remember the distinct "multiple master cylinders, they can be different based on which one, and the 80s have low drag disc brakes which adds another layer of double checking required" The only...

    Rear Brakes Locking Up

    well with an attitude like that im more than happy to be a nuisance You already asked me to be nice and I apologized and turned the tone down. And Im not the one who needed to be asked by numerous people to see your master cylinder before you finally did. Early on this discussion the...

    I see now, i wasnt saying move your oil pressure sensor, (sensor not a switch) but providing a location that receives oil that is in the engine But youd like to put it on the filter adapter for the oil cooler for ease of access/near firewall? Is that what im hearing? Ill do some diggin,id...

    Rear Brakes Locking Up

    Having the lines reversed would explain the difference in volume and pressure that could make those rears lockup and fronts not do much But id like to point out, that, his answers have been good and complete, but the issue was found only AFTER he posted a photo. Which he wouldnt do. If this...

    thats what the gmt400 did ,used the port at the front and the extension for the oil pressure sensor

    Rear Brakes Locking Up

    if everything was replaced, tested, and to stock condition (the testing would verify that) it would have to work for it not to work, means that something is missed, mixed up, or similar

    Rear Brakes Locking Up

    except in reverse, theres no self-energizing action in reverse I believe some drums trade being self energizing to be directionally insensitive but require more force/fluid and so not common on american ones

    Rear Brakes Locking Up

    lol you literally did the pad on the pedal, good guess on my part So what im hearing is you didnt replace anything. im glad I asked. There is supposed to be a filter on the hose to the booster, and it has to be very stiff walled booster tubing (theres a specific SAE number that corresponds to...

    Alternator amps

    yes, i thought he had a 12si already The 12 si is just a stronger 12si There is , however, a delta wound alternator that is the same as these, thats called the 27 or 15si , i think the CUCV came with it. more charging potential with the same size. The electronics are the same and the...

    Alternator amps

    i dont advise it but as it stands CS130 have a heat problem that kills them Rebuilds just using cheap parts dont make that better There is a modified CS130 case by a company online which makes them cool better, youd need to spedn a lot for their custom alternator One could rebuild it going...

    Rear Brakes Locking Up

    so you said you checked everything 5 times, but you verified you replaced things as a parts canon and did not inspect things up close So you are lying to us or maybe us and yourself You needed to replace ALL the parts? To the brake pedal pad, to the drums/discs at the other end, to the...

    Rear Brakes Locking Up

    the backs get pressure first, the to overcome springs and begin their self-energiziing design, then the fronts have less distance to move to apply, and once the rears were beginning the fronts are getting the pressure and they begin braking, so it feels balanced Then the pressure is mostly in...

    Rear Brakes Locking Up

    brake hose diameters swell in and restrict, uncle tony showed one that had a pin hole diameter to through it And was like wow, but when they do this they are not sound structurally, any reverse of the pressure in the system might check valve the line to stop the fluid and thus hold pressure
