    Found my problem or rather it found me today

    Fuel-Pumps.net Another option might be to pull the module from the tank, open it up and replace just the pump inside with a Walbro.

    Transmission swap help/instructions

    If he's swapping to a 4L60E transmission, the transfer case will have to be changed to a 27 spline input if it's 4WD.

    Help please: glitch in 4Hi + HD quad wiring, and I used schematic!

    The following information is intended for novices, "old" heads probably already know all this. That said : In the schematic, the "Low" and "Hi" relays could be 4 pin relays while the "4 Hi" must be 5 pin. 5 pin relays have an 87 and 87a pin, some have pins 87 and 87a both normally open (NO) and...

    Upper control arm contacting frame (stop)

    Be careful using the "lift" keys. Simple geometry says if the control arm pivot points remain the same you can only raise the vehicle a set amount before contacting the droop stop, regardless of which keys are used.

    10 bolt to 14 bolt swap

    I think a lot of the greasable u-joints that break are because of being installed improperly indexed. The cross should be installed with normal direction of rotation compressing the grease zerk (threaded) passage.

    Coolant loss 5.7 vortec

    Most if not all with the bleeder screw is because the top of the engine is higher than the top of the radiator. Vortec heads are known to crack, especially if they've been hot (overheated), so don't overlook that possibility. Hopefully you have it fixed.

    Lost 4th Gear; Code 28 and 58; 4L60E

    My ATRA books say that 4L60Es with a KCD code (5.7L, 4WD) or at least some of them came from the factory with the "Corvette" 2-4 servo. Might want to check it out before laying money out for a new 2-4 servo.

    Spider injection issues

    I don't know but it seems to me that the cylinders with wet plugs are the ones misfiring and all that raw fuel is being sensed by the pcm, causing it to pull fuel and driving the other cylinders lean. The old black box pcm had two boards inside, GM issued a TSB and kit to fix a bad ground issue...

    Bad fuel pump?

    The regulator is as you say on V6 models (as shown in the Haynes manual 14.11) but your C1500 is a 5.7 correct? The regulator is on the passenger side as the "fuel meter body" is rotated 90* from the V6 orientation.

    1994 350 TBI Running Super Rich!

    Might want to check the fuel pressure regulator in the throttle body, hard to tell if it's leaking when the engine is running though. Seen them leak enough extra fuel to foul a spark plug. If it's leaking and the injectors are good otherwise then a regulator rebuild kit is available.

    K2500 lower control arm sizes???

    This type LCA is in my 96 Yukon 4WD.

    Bad fuel pump?

    Rich on bank 2 could be the fuel pressure regulator as that's the side it's on. And if it's constantly rich I would think the computer would pull fuel to lean the motor out but only in closed loop, should be running off a fuel table in open loop until it warms up.

    New Fuel pump and assembly, no fuel pressure 2000 ét

    "mine is unique under my hood", "Took 3 fuel pumps and 2 FP assembly's to get everything together", " I just put a new fuel pump in it, had to frankenpump the assembly". So this truck has had an intake system change to a throttle body injection system? What computer is controlling the injectors...

    Here's a link to the siu automotive YT channel, covers the 10 bolt rear rebuild. Looong video but good info.

    Fuel Starvation.

    Might try replacing the fuel pump relay if it's the original, contact points do quit sometimes. Something to think about anyway.

    Where can I find a 4L60E Label code deciphering chart or Guide?

    How involved is removing a shift kit?

    Probably the first thing to do is a little research. Educate yourself on the 4L60 series of transmissions. Get a manual with all the updates or go to YouTube and watch the video series from Transmission Bench. Good info and Jimmy walks you through a full rebuild, or you can buy the whole series...

    Who has the best reputation for reman 4L60E’s?

    Unless you're in a hurry I'd be inclined to agree with stutaeng. I rebuilt my own several years ago using an ATSG manual, which is written for the 93-94 transmissions. It took me a couple days and wasn't too bad but mine was a 96 model so there was some differences. Afterward I found an update...

    5.7 vortec not running right

    Have you checked compression? Low compression on one cylinder is generally not very noticeable until it's put under load.

    Very persistent misfire, help

    Have you checked the injectors for those cylinders? Any possibility the injector wiring for those two are crossed? An injector noid test light would tell you if the injector signal from the ECU is getting to the connector.

    1997 3500 vortec issue

    Does it have an aftermarket security system, if so uninstall it. Or is it the security light in the instrument cluster, if that's the problem it may be VATS is preventing it from running. Right in that time frame GM started using keys with a RFID chip, which means a switch with key replacement...

    That line is the PCV and yes that will create a big vacuum leak.

    Upgrading to mpfi should i do the lower intake gasket?!
