FIRING ORDERS

To avoid confusion, ALWAYS replace spark plug wires one at a time.

The most important thing to remember about the removal and installation of a distributor, cap or spark plug cable is that all wires MUST be labelled before they are disconnected. Keep in mind that these figures depict a firing order where the distributor cap terminals are relative to EACH OTHER only and they do not necessarily depict the tower positions in relation to the rest of the engine. This is true because any distributor which has been removed and reinstalled may have been installed with the No. 1 spark plug tower at any position (360 degrees) in relation to the rest of the motor, as long as the rotor aligned to the No. 1 tower when the No. 1 cylinder was at TDC of the compression stroke (valves closed, ready for the plug to fire). As long as the remaining wires were connected in the correct firing order sequence (depending on direction of distributor rotation) the engine will run. DO NOT EVER remove more than one wire from the distributor cap at a time unless you tag ALL wires and towers to assure proper installation.

SOURCE: 1987 gmc s15 2.8 litre. Clutch only goes half way

I don't know that specific vehicle, but if its a hydraulic clutch it sounds like either you have a leak and your clutch fluid is low, or the master or slave cylinder could be bypassing internally. Check the fluid level in your clutch master cylinder. If its low, you should top it off with brake fluid and will probably have to bleed the system. Also look for leaks. You can probably find info or a video online of how to bleed the system. Its a bit hard to explain without illustrations or pictures. Not really very difficult to perform. Good luck.

SOURCE: replace u joint on GMC S15 pickup

You'll need a bench vice for this. A few sockets help as well. Once you get the shaft off the truck, put a smaller diameter socket on one side and a much larger diameter socket on the other and sandwich in a vice. Compress vice to drive the U-Joint through shaft (smaller socket will drive the one side through the other with the much larger socket). Installation is the reverse of removal.
