    4.3 no start

    For sure, that was a super cheap distributor, like $50 I think, the original one had excessive play when he bought the truck, so that was intended to be a temporary fix, lasted 4 years so I guess it served it’s purpose, caused me some headaches there for sure though haha. Thank you guys again, I...

    4.3 no start

    Got it started fellas, appreciate all the help. Did the compression test everything was good there, ended up putting a cap and rotor on it and it fired right up, kind of hard to believe I had two distributors and both of them had bad caps and rotors but it runs so I guess I won’t argue with it...

    4.3 no start

    I haven’t gotten the chance to work on it much, I went to the junkyard yesterday and pulled a distributor, coil and ignition control module, I picked a truck that had been hit hard in the driver door, so the parts should have been good. Didn’t change anything unfortunately. I’m going to do a...

    4.3 no start

    The contacts inside the cap were really coroded looking as well, I took 1000 grit to them and cleaned them all up. I haven’t tried cranking it and turning the distributor. there is a little bit of movement if the retainer bolt isn’t tightened down all the way, so that’s something I could try...

    4.3 no start

    I stopped by and worked on it a bit, you can see what I’m saying about the distributor it seems off but not by much, and I simply can not get it closer I messed around with it for probably an hour taking it in and out gradually turning the oil pump shaft to try to get it to line up better and I...

    4.3 no start

    Yes that’s how I did it, I think the rotor points back to just ahead of one of the bolt holes for the cap, the factory one has a nice little line to line up the roll pins on the distributor gear, this one is aftermarket and doesn’t have that unfortunately, but I did rotate it back a bit Edit: I...

    4.3 no start

    I had an awful time getting it lined up because of the shaft from the oil pump, very hard to find it with a screwdriver to turn it, there is an arrow that is molded into the aluminum base of the distributor that the copper part on the rotor is supposed to point at, when I finally got that it was...

    4.3 no start

    I can’t imagine so, I’d put money on me messing something up before I would the factory making them wrong haha. I’ll check them next time I’m up there I have the old timing set laying on the shop floor. The new timing set were GM parts too by the way, so definitely should be right.

    4.3 no start

    When I tried starting fluid last night it popped back through the intake and blew compression out like it’s out of time. I really don’t think the mechanical timing could be wrong following the steps that were in the video I linked. I don’t have a fuel pressure gauge or a compression gauge I’ll...

    4.3 no start

    Yes, the dowel pin points at 3 o clock, I took off the chain sprocket and lined up the dots on the cam gear and the balance shaft gear, and then I had the number 1 cylinder up and both arrows pointed at each other on the timing chain sprockets, like your picture. They’re arrows on this truck...

    I don’t know if this helps, but this YouTube short is exactly what I did the last time around

    4.3 no start

    it started and run for a couple days but then it wouldn’t start at all and was blowing compression through the intake when you’d try to start it, that was when I just put it back together like it had been. But then I redid the job and that’s when I changed the timing, so it’s probably wrong for...

    4.3 no start

    thank you for the response, I set it to TDC when I tore it down, turned the engine over by hand with a ratchet and felt for compression on the spark plug port. But as I said the arrows were both facing straight up instead of at each other, so I pointed them towards each other, I didn’t really...

    4.3 no start

    Hey guys, I apologize in advance this is going to be a bit long. I’ve been working on my brothers 2000 4.3 Sierra. It’s had way less power than it should since he’s owned it. It’s gotten to where it will not start when it was cold, he wanted to replace the timing chain and sprockets to make sure...
