    Tbi help!

    Yeah I'm sure the distributor isn't very good, but it's what I could get locally, hopefully it lasts ok at least for this year, this truck probably won't get more than 500 miles on it a year so hopefully that cheap distributor will last. I may order a better one from rock auto to put in when I...

    I had a pressure gauge on it recently and the pressure seemed very consistent, however that's not to say that it would be now, if I get a chance I'll have to put my guage on when I'm using the truck and see what it does. Never heard of using a timing light to check the injectors how do you do...

    Tbi help!

    Well I think we got it fixed finally. I found someone locally who knows more about the tbi systems come look at it, he said that a lot of the failures he saw were the ignition control module in the distributor and he said to replace it. I found a new distributor for just a little bit more than...

    Tbi help!

    Yeah unfortunately I am, i checked the casting number on the block when I first started working on it because I didn't trust the sticker on the air cleaner. I really wish it had the 427 instead because even if this motor runs well it's still going to be gutless with the amount of weight we will...

    Well to be honest I don't know the entire story on it either, but basically what happened is my father bought this truck maybe 10 years ago and was going to put a different bed on it to use it. That never happened so the truck mostly has just sat a lot of that time but we would run it...

    Tbi help!

    Well I got the gasgets in and re tested all my lines and cleaned my electric connectors when I reassembled it. I think it runs a little better but it still hesitates pretty bad, if you just floor it it almost dies and only really revs up if you let off the gas and then slowly try and accelerate...

    Tbi help!

    Quick update: I am currently in the process of replacing the intake manifold gasgets. I got looking and they were so cheap for this motor and because it's a truck there so easy to do I figured I would do them just to rule it out. I didn't really see any signs of the old ones leaking though so...

    Actually I just replaced it, I had hoped it was the issue as well but it didn't change anything.

    I also checked if lowering the fuel pressure would help and it made It didn't, matter fact if I got under 12 psi it would just die, I assume this is because it's a "big block" and needs more fuel. I also checked if the egr was the problem, I blocked off the ports with a plate and no difference...

    Tbi help!

    Well I looked and I can't split them apart because for some reason the exhausts a welded together before the muffler, I don't know if that's original or not, however it does seem to flow really well out of the muffler ( like it will blow floor dry completely across my shop floor) so I don't...

    Tbi help!

    I Don't know if this makes a difference but this truck has no cats. What would happen if I unhooked one of sides of the exhaust, is there something specific I should be looking for?

    Tbi help!

    Ok so I did a bit more testing and here is what else I found out: I set timing to 4 degrees as it recommended for the big blocks ( I unhooked the advance wire, set the timing, then disconnected the battery and connected the advance wire while the battery was unhooked, is that the correct...

    Would aftermarket fuel pumps put out to much pressure like that? I see one of the (truck has dual tanks) looks like it's been replaced. I've got a tap still in the fuel line I'll have to see if I can run a ball valve off of that with a return line and see if I can reduce the pressure some

    Tbi help!

    Hi all, new to the forum, looking for any info that would be beneficial on these tbi systems. I have a 93 chevy kodiak with the 366 gasser in it and I'm really having a hard time getting it to run right. I know this site is for the gmt 400s but I was hoping someone on here could just share any...
