Is the coil connected to the ditributor? did you knock any connections off in the process? Does it turn over but not fire? do you have spark at the plugs? Are you sure of cylinder location in respect to firing order? Did you-and check this first as with any elec. problems-blow a fuse in the ignition circuit? good luck!
1993 k1500 5.7 throttle body injectors clogged?
The idea that the injectors are clogged is almost never the problem - if you're not getting fuel - then most likely it isn't the injectors - you don't give symptoms so I am in the dark but I will suggest if the engine isn't getting full power it isn't the injectors. Also try taking one off - just one - - and see if a local Advance or dealer can check just the one - if one works then most likely all do as they all got the same gas.
Stalls out when shifted in reverse or drive
this is usually caused by a sludged up idel speed control valve, do the following to correct an clean it.
, Get a can of intake cleaner from any local parts store, not carb spray, intake cleaner, it is made by a company called CRC, remove the air intake hose to the engine, hold the idle high so the engine won't stall, then spray the can of cleaner into the intake while keeping the engine running, use at least 1/2 the can, shut down the engine and disconnect the battery for 5 minutes, then restart and complete a number of mixed driving cycles, town, freeway, stop and go etc., after a few days the problem will go away as the system will relearn to the clean intake.
No power to injectors 350 tbi
Check the crank sensor for failure. It is relatively easy to change and it is what tells the computer that the engine is turning over. If there isd no crank signal the computer wont fire the injectors.
90 k1500 tbi no fuel from injectors
from the sounds of it its going to be one of 3 things 1) the injector is bad or 2) there is no power getting to the injector 3) bad relay switch.
1) to find out if the injector is good. pull the injector out and with some wire ground one side and touch the other side to your battery, every time you tap the wire to the bat you should here the injector click..
2) if injector is good get a test light and test to see if power is coming out of the wires that go to injector( on some vehicles you have to have the motor turning over befor power is sent through wire, so have someone turn the key while you check the wires with test light)
I'm trying to replace the idler arm and having a
Make sure the jack is under the A arm and not on the frame. You could buy or borrow a ball joint seperator tool from a parts store. Or try placing a brass drift or a socket on the steering knuckle and hit it with a hammer while prying the joint apart with the pickle fork (two people). As for the idler arm you should use the special puller made for removing it.
