    1994 k1500 IAC issue

    Got my new pigtail and iac in the mail today and went ahead and installed them, didn’t quite have the effect I was hoping for. When I started the truck up to get it to temp it did start and idle differently than before, a step in the right direction. So I went through the pdf you sent and set...

    1994 k1500 IAC issue

    I forgot to add the part about disconnecting the iac in my original post lol, a just gave that pdf a quick glance looks like it’s got lots of good info I’ll have the new pigtail by the end of next week and I’ll be able to give it a try and hopefully I get somewhere with it.

    1994 k1500 IAC issue

    Replacing the pigtail is probably a good idea, I went ahead and ordered one aswell and a new iac just to start fresh with it, I do know how far the pintle stick out should be during install but I do know that it can’t be more than 29mm or it will bottom out but I can’t find anything on a...

I can’t find any information on what I’m experiencing, (1994 k1500 5.7, tbi chips chip, newer remaned acdelco computer)my IAC moves and reacts to when I open the throttle blades, I can see it moving in the little...

    Tbi cuts off please help

    As for my iac I cannot get the base idle set properly, it’s just a new one that was in the throttle body when I received it, then I swapped it for the almost new one in my old tb, correct me if I’m wrong but the procedure should be Jump A and B Turn key on, wait 30 seconds, unplug iac Start...

    Tbi cuts off please help

    My cam is Chevrolet performance 14097395, distributor is a Delphi for a ‘92 z28 Camaro, vortec fuel pump can’t remember the brand. The truck is a fresh build so everything has been on for less than 5000km. I always get acdelco or Delphi or genuine parts, I want to try messing with the fuel...

    Tbi cuts off please help

    I have a 1994 pickup 350 tbi with vortec heads, 650 cfm throttle body, 18 psi of fuel pressure, a chip, and other supporting mods. I’m having a problem where when I mash the throttle the truck will begin to accelerate and rpm’s climb and then all of a sudden it just dies. It doesn’t stall but I...

    No spark

    I thought it was just cheap crap when my brand new Delphi icm failed in 150 kilometres, so I put on the used gm genuine I had before expecting it to solve my issue but I don’t think it’s a coincidence that 2 have just failed lol

    No spark

    I’ve got a pertronix coil, makes sense that a stock icm can’t handle it. I’m going to try and borrow an icm and coil from work today and if that solves it I’ll keep replace the coil and icm with hood quality new stuff. Eventually down the road I’ll put back in the pertronix coil aswell as a...

    No spark

    1994 Chevy pickup 5.7, took the cap off and it still looks brand new aswell as the rotor none ot the contacts fell off, used an ohm meter to check the pickup coil and I swapped coils with another one. I’m starting to think it’s my icm again I found an article on how to test it so I’m going to...

    No spark

    Had a code 54 ended up being my oil pressure sensor, now I’m getting the injectors to pulse during cranking but I’m not getting any spark. It’s a brand new Delphi distributor the ignition module went bad the night before so I swapped it with my old gm genuine, when the module failed the...

    350 TBI build

    Also I’m curious do your factory guages still work? If so how did you accomplish that I was told the tbi computer controls them so I’m not sure if mine would work with a different fuel injection system

    350 TBI build

    I have think I have a 4L60E, the truck is a 1994. I’m still trying to decide on which direction to go with the motor, now I’m looking at crate 350’s that make 333 hp and 389 torque that why I am considering the fitech over the sniper. But you have a point at the lower power level, transmission...

    350 TBI build

    How about the Fitech go street self learning efi system, it’s $1100 CAD and supports up to 400 horse which is more than enough for me. I saw a post on another site about a guy that did a carb swap and was able to maintain the tbi system to control the transmission and gauges, I’ll try to link it...

    350 TBI build

    I’m looking to go to a different injection system for more efficient fuel delivery, and I have the 4L60 transmission.

    350 TBI build

    Will this kit control the transmission? Or do I have to worry about transmission control at all?

    350 TBI build

    What’s the best way to convert the tbi to efi? I saw a truck trend article about an edlebrock system they put on a ‘95 Tahoe that gave decent power gains, however the article was from 2004 and I can’t find anything similiar to the system they used

    350 TBI build

    I’m planning on building a motor for my truck, something I can drop into when I’m finished it because the truck runs as is, but not well so i want to build a motor that is more lively than stock, but budget in mind what’s the best way to go about it? Stock compression pistons? Mild cam? Heads...

    SAS 2X4 to 4X4 conversion

    I am looking into doing a SAS 4X4 conversion on a 1993 Chevy 1500 2WD that I’m looking at, I’d be using off-road unlimited parts and I haven’t decided between the 10 bolt or the Dana 44 yet or transfer case (recommendations welcome) my main question right now is would there be any transmission...
