    Rough idle after installing new fuel pump

    87 k10, 350 TBI. I don't know if it matters, but the VIN codes for a 305, prev owner speapped in a 350. Anyway, after my fuel pump finally went yesterday, I replaced the fuel pump relay and the pump. Now the truck idles like it's running on alcohol, but once I get on the gas and start driving it...

    What have you done to your square lately??

    Just finished cleaning up my engine bay wiring on my 87 and installing an O2 sensor, along with a coolant flush and some new antifreeze. Also chased down a coolant leak to the heater hose connection on the manifold. She seems to run a little better now, and the coolant no longer seems to...

    Fuse box plug

    This should solve my problem, now that I know where it is. Thanks for the pics, saved me a lot of time searching every pin in the box

    Fuse box plug

    I don't suppose you or anyone else has a pic of the wires from the injectors that go to the fuse box, a pic of them actually going into the other half of the plug, or whee they splice into. The supposed ECM 1 pin in my plug is occupied by a different wire

    Fuse box plug

    Can anyone here find or know of any diagrams that show which wires on the fuse box plug in the engine bay go to which fuse? I have looked and looked and cannot find any. I need to know because I want to check the ignition wires, and my injectors have to be hooked back up, but I don't know which...

    Where does it get the vacuum from, is it manifold vacuum or elsewhere?

    Engine removal 87 K5 350 tbi with tranny or not

    That depends if you wanna just do an engine swap, or the trans and the engine. If it's just the engine you desire to change, then don't pull the trans too, but if you want to swap both then pull them together

    Kick panels

    My 87 v10 silverado has kickpanels, or at lat one on the passenger side. My issue is that they're vacuum operated, and i have no idea how the hoses run or where they go to, as my engine bay is missing some vacuum lines and I have no diagrams. Id like for them to work, as the AC is not in working...

    Ecm

    Do the ecms differ in the 87 v10 for the 305 engine and the 350? My truck was originally a 305 according to vin (HXHF) but the previous owner claims the engine that was swapped into it is a 350. Is there any difference in the ecms used for each engine or are they the same?

    ISO TBI vacuum digrams

    Now will this be effected by the fact that the block is not correct? The block is a pre 87, and there's no air pump or ac pump on it. Will this be an issue for the vacuum system, can it be worked around?

    ISO TBI vacuum digrams

    I have an 87 v10 Silverado. It's missing many vacuum lines, as well as has some it doesn't need for egr ECT. While I'm rewiring it, I'd like to get the vacuum lines straightened out, and was wondering if anyone on here has any diagrams for the lines, as I cannot find them

    Vortec heads

    I had meant overhead valve cams, as opposed to the stock 80s pushrod system. My bad

    Vortec heads

    I have an 87 k10, so it's got the TBI. However, the block in it is older, meant for a carburator. The TBI top end bolted right up to it apparently though, since it runs with no issues. However, what needs to be done for a vortec head swap, or would it even be possible with this block? And how...

    Popping/backfiring

    I recently bought a 1987 chevy k10 with the 350 tbi. I just got it registered yesterday, and drove it more than ten feet for the first time today. It had run fine in my driveway every time i ran it over the past two weeks. I bought a few gallons of gas before I tried to drive it because the...
