    Dies without throttle until warm

    @Road Trip Man thank you for this OLD-SCHOOL-NO-SCAN-TOOL, methodical, logical, rational, and most of all freely offered elementary troubleshooting plan. THIS SHOULD BE SOMEHOW AUTOMATICALLY PINNED AS A NUMBER ONE COMMENT FOR EVERY POST REGARDING POSSIBLE SENSOR, MECHANICAL, AIR, FUEL, AND...

    Dies without throttle until warm

    Here's a video of exactly what's happening.... starts by barely hitting key (ONLY WHEN COLD START)..... Runs as smooth as you could ask with idle at 1500 rpm... AS SOON AS it hits 1k rpm it's like I switched key off..... I can get it to restart with fluid but I have to keep throttle to it...

    Dies without throttle until warm

    Alright guys I have a lot going on right now so didn't get to touch truck until right before dark tonight and just wanted to see what it would do one more time. I don't recall if I mentioned it but when the idle is coming down, as soon as it hits the 1k rpm mark (factory dash tach), it...

    Dies without throttle until warm

    Brand new everything... fuel pressure is 15 constant, except when off of course. But for it to run so perfectly then just stop dead. And after that rough idle until motor warms up then running and idling perfectly until motor is cold then same process over. I don't have scan tool nor access...

    Dies without throttle until warm

    Ihave gone through every diagnosis and repair and service manual. Have you not noticed that there are about 5 or 6 parts and about 5 or 6 problems that are mentioned in EVERY SINGLE issue on a tbi? And usually unless you find the exact combination that works for your particular truck it doesn't...

    Dies without throttle until warm

    I posted a reply to a thread I had covering my long process of learning about this motor and haven't received any responses and I also think this situation is one that may help others because 99% of what I find is the opposite of what I'm experiencing. 94 k1500 5.7TBI NV4500 transmission. What I...

    Tbi backfire through intake

    Ok gentlemen, I have gotten everything back together yet again and got her fired up. But I still have an issue, albeit different from the last. I started it, ran at about 12-1500 rpm idle for several minutes then just cut straight off like the key was switched off... would crank back up but...

    Tbi backfire through intake

    One more side note..... the icm (039) that I picked from my treasure yard pile of course unbeknownst to me needed thermal paste. I searched thru 4 or 5 local parts stores with no luck (WTF i guess everybody uses dielectric grease which is the opposite of what you want and is my suspicion that...

    Tbi backfire through intake

    Thanks for the words of encouragement. I never intended to do anything other than replace a leaky power steering hose and redo my grounds. But with no knowledge of all the things that went into making it right I began disassembling things I had never seen before except in pictures but things...

    Tbi backfire through intake

    If it was enough for my wife to smell it that quick, it's too much...... but seriously from the few seconds it's run here and there, it's way too much... I would be adding coolant every time I stop..... it has to be at the China wall I will confirm today

    Tbi backfire through intake

    See above re: quick connects.... My leak appears to be coming from intake/ head junction..... but with my borescope being suddenly inoperable when I need it most, I can't get a good look or picture...... being blind in one eye don't help none either it always seems to be in a location where I...

    Tbi backfire through intake

    No quick connect José No quick connect hose anywhere on my truck..... This is what I have and it's solid and not leaking a drop but yeah that was my first suspect lol.... Thanks for the info though.....I wish that I would have been so lucky..... looks like I get to take all this pretty work I...

    Tbi backfire through intake

    So at the end of the video you can hear my wife mention antifreeze.... This morning I look under the truck and see a little puddle.... crawl under and it appears to have been dripping from bellhousing dust cover.....I look further up and yep wet at back of block.... Get my little borescope out...

    Tbi backfire through intake

    Ok so let me back up and punt..... I know my timing is dead set on zero by timing light..... All my sensors have tested out with the exception of the esc module, which is unplugged at the moment..... Est bypass wire connected..... I can get it to crank and fire..... I can only get it to crank...

    Tbi backfire through intake

    I still would like to know if anyone has any info that could help me not waste any more time with wrong parts.... Got my old injectors back in, they're both clicking strong with a DC pulse, but I'm not getting any spray now in the TB..... ALL SENSORS ARE CONNECTED EXCEPT <ESC MODULE> ...... I...

    Tbi backfire through intake

    I have one more question..... I have a pile of MAP sensors, ICMs, and TPSs...... Can someone help me out with knowing which part numbers I should/ should not use of these parts? Or where to reference that info.... It is also quite possible that one of these may be leading to some of my...

    Tbi backfire through intake

    Ok so I got the injector part of the equation figured out at least..... Upon closer inspection, it appears that the injectors I pulled are specific to a 4.3.....‍♂️‍♂️ At the time I pulled them, I had no idea there were any differences but I did at least look at the numbers and thought they were...

    Where exactly is my tach wire?

    So that's what the unused 2 wire pigtail on my 94 is there for!! I been wondering lol
  23. Rustjunky67

    Tbi backfire through intake

    Yessir that's what I gather.... I've read some posts about bypassing it but not sure yet if that is actually a viable option...... So any clue as to why both injectors are streaming so?
  24. Rustjunky67

    Tbi backfire through intake

    So for some reason I have paid ZERO attention to this bugger...... the ESC module...... and it hasn't been mentioned in anything I've watched, read, or seen posted..... But I disconnected it and truck crankeded up and was idling on point and just as smooth as you please..... for a minute that...

    Blinker making the injectors pulse.

    DANG Y'ALL!!! Finally we have circumstantial; and possibly imperical, or at least anecdotal evidence for someone who is not low on blinker fluid!!! That's a first I've come across
