    Electrical Load Causing Weak Blower Motor?

    Probably the last thing you want to hear after an LS swap and wiring all that other stuff in and all your electric comfort upgrades, but are you running all these new electronics off the original fuse box?? I did a METRIC TON of new wiring but I installed a new second fuse box wired direct to...

    Stolen truck found after 30 years

    I think your cheapest option is to move out of California. Better for you psychologically also………

    700R4 Gear “Hunting”

    Unplug the wire harness on the passenger side of the trans. This will bypass the TCC completely. If you still have problems, I’d say it is the 3/4 clutch pack or you have pressure problems in the trans.

    Random power loss to engine and accessories

    This sounds like a ground issue somewhere but, I think we can solve this. Can you tell us a little bit about your powertrain set up? Is this a stock engine or is this a redo?

    Fuel selector valve low volts

    The fuel tank selector valve gets power from the switch. The switch gets it direct from the fuse block via the pink wire.

    Lost Fuel Pressure

    If you get under the truck and have someone throw the switch, you should hear the valve move. If you hear it working, I’d start looking at the fuel pump

    New guy... LED issues

    Put in a low amp blinker relay first and see what you have. This is an essential part of switching to LEDs. Don’t forget the hazards are a separate relay. 2Pin LED Flasher Relay with... https://www.amazon.com/dp/B0CNK6VM7X/

    700r4 tv cable adjustment

    Get a pressure test kit from Amazon. They are like $25. Test it before you even move the truck, specs are attached. It will smoke 700r4 in five miles if you don’t. This is the only “right way” to do this.

    Fuel tank switch

    It’s the switch, or the switch valve. Have someone throw the switch a couple times while you are under there and see if there is any life going to it. The switch is like $10 from LMC. Put it on a multimeter and see if it’s actually bad first. My bet is switch valve or another wiring problem...

    Fuel tank replacement on 1987 LS swapped square body

    Replacing the tanks is just good hygiene for the motor. After 40 years, and at $90 each, it’s a no brainer. I would expect you have a bad fuel line, but if you are taking them down, I agree with your buddy and just replace it. Also agree with ditching the rock guards. Those were one of GMs worse...

    Tank selector

    Suburban tanks are good, but Way more work switching to a single 40 from dual tanks instead of just swapping the valve if it’s bad and you lose your spare tire mount. Just about every auto part store and Amazon sells the correct 6 port Pollak valve. They are all under $100, last one I bought was...

    Dash turn signals not working

    I’d check the bulb socket with a test light and work backwards.

    No power at some locations in fuse block

    Try checking continuity across the accessory circuits in the fuse box to see if you have a burned cross over, but I doubt it. I think you will probably find the problem someplace in your wiring harness swap. This may atleast tell you what wire to trace.

    I am pretty sure my Charcoal canister is Clogged!

    You said you eliminated the switching valve and hooked the tanks directly to the fuel line??? I am curious to hear how you did this, as the switch valve also switches the return line to the correct tank, not to mention switching what tank you draw from.

    700R4 Lockup Torque converter control issues solved

    The vacuum switch on the passenger side contributes to the spark control system. The vacuum switch on the driver side is for the TCC. The green wire with the orange plug is a diagnostic circuit for a 700R4. If you give it 12v in fourth gear it should force the TCC lockup. So you can determine if...

    Electronic fuel pump wiring

    You definitely want the safety switch. This is a little more cost effective https://a.co/d/0aPCdidk Here is my pump wiring diagram using one or two relays.

    Fuel tank and hose help

    Don’t waste any more time with this amalgamation the PO left you. Spend your energy switching it back to OEM and diag from there. It doesn’t sound like anything is right with that fuel system.

    Anyone running this engine?

    Not the model you are looking at, but I put this one in last year. Positive, it runs as advertised. It actually came with 370 HP on the dyno. Turn-key does not really mean “just turn the key”. I had to spend a lot more money on collateral parts to get it to work, and a lot more time tuning it...

    Any holly sniper 2 experts here

    Holly snipers are awesome pieces of equipment, but they need to be tuned. Even the set up wizard does really set up anything. prime fuel, IAC, ASE; there is a laundry list. I actually used chatGPT to dial in my tune. It seems to be running well now. There are a lot of videos on line that I...

    torque converter lock up

    There is three wires going to the TCC lockup in the 700r4. Yellow goes to an egr bleed valve. You can bypass that, most people just cut it when they bypass the spark control. Green is a test circuit. You may have a green wire by the fuse box with an orange end. If you give it 12v in 4th gear...

    Good R&R 16-gallon gas tank video?

    I usually cut up an old inter tube and use some contact adhesive to keep them in place on the tank
