Wiring colors for what system?

Big fat red wire from battery to the large post on the large solenoid post and the small purple wire on the small post on solenoid. If there are 2 small posts, use the one marked ign.

Take a sharp pick and with a hammer slowly remove the broken insert a little bit at a time.

Remove cooling fan, all belts, radiator shroud, pulleys, water pump and harmonic balancer. Probably will need to remove the alternator and power steering pump also. Drain the coolant. loosen the oil pan removing the front 2 bolts on both sides. Take all bolts from the timing chain cover. Carefully remove it from the engine. You should be looking at the old timing chain. Rotate the crank until the two dots, one on the cam gear and the other on the crank gear, are positioned together. Cam gear dot on the bottom, crank gear dot on the top. Take out the 3 cam gear bolts. Slide both gears towards the radiator keeping them lined up. Install in reverse order.

This model of Chevrolet uses a throttle body fuel injection. When you state that it does not take the gas, do you mean that the engine cranks over but will not start? If so, first take off the air filtering system and with a flashlight look down the throttle bore while someone cranks cranks over the engine. You should be able to see fuel spraying down the bore. If not, check fuel pressure. If that is ok check to see if the wires going to the throttle body injectors go on and off while cranking. You could have a fuel problem or an electrical problem.

Are we talking about a car engine or an advanced cryogenic engine?

have truck scanned for a trouble code active or pending this will cause no start conditions

Here is the firing order for your vehicle. Good Luck.

You have many problems. 1. For the fuel pump i. Check fuel pump fuse in fuse panel. ii. Turn on the ignition key to start position without engine cranking. iii. Listen at the same time for 2 seconds if you can hear the sound of the fuel pump near the fill fuel neck (remove the fuel cap). iiii. At the fuel pump relay place, a test light back probes the green wire or trigger wire with a test light. It is activated by the PCM (Powertrain Control Module) for 2 seconds (priming the fuel system). /When you start the engine, that same wire will receive a + signal but steady. Then you should find your fuel pump problem. (could be the fuel pump itself not working). If you need to change the fuel pump. You have to remove the fuel tank. When the fuel tank is halfway down (before removing the fuel pump) test the + signal at the tank (could be a wires problems) 2. The neutral light problem belongs to the neutral switch system (PRNDL) attach to transmission. 3. Starter Problem i. Could be rusted positive and negative connections at the battery (Voltage drop in the + battery terminal should not be more than 500mv. if more remove terminal and clean it. Same thing at the starter motor's end (Same thing with the ground at the Battery to the engine. if OK then the starter motor itself is the defect. Hope it helps.

Duplicate questions???

You have to know : it is a question an answer site about "Chevrolet Vehicle Parts & Accessories" What is your question?

Are all filters clean, tank venting, throttle body set correctly. Disconnect baterry and reboot it. Maybe we can get lucky

The fuel tank float assembly is the likely culprit for your bad fuel level readings at the gauge. In fifty plus years of working on cars/motorcycles/boats I've never replaced a fuel gauge because it wasn't accurate.

It might have jumped time a tooth or too

Crank position sensor.
