Its your No. 6 Injector. I had the same problem on my 97 Jimmy. Replaced the SPYDER injectors and it runs fine now.

1. For the 4.3L engines which are equipped with screw-in type rocker arm studs with positive stop shoulders, tighten the rocker arm adjusting nuts against the stop shoulders to 20 ft. lbs. (27 Nm) on 1994-96 models and 18 ft. lbs. (25 Nm) on 1997-99 models. No further adjustment is necessary, or possible.
   
2. For most 4.3L engines which are not equipped with screw-in type rocker arm studs and positive stop shoulders, properly adjust the valve lash. For details on valve lash adjustment, please refer to the procedure in Routine Maintenance . (see below)

4.3L Engine

The 4.3L engines may be equipped with either of 2 rocker arm retaining systems. If your engine utilizes screw-in type rocker arm studs with positive stop shoulders, no valve lash adjustment is necessary or possible. If however, you engine utilizes the pressed-in rocker arm studs, use the following procedure to tighten the rocker arm nuts and properly center the pushrod on the hydraulic lifter:

1. To prepare the engine for valve adjustment, rotate the crankshaft until the mark on the damper pulley aligns with the 0? mark on the timing plate and the No. 1 cylinder is on the compression stroke. You will know when the No. 1 piston is on it's compression stroke because both the intake and exhaust valves will remain closed as the crankshaft damper mark approaches the timing scale.

Another method to tell when the piston is coming up on the compression stroke is by removing the spark plug and placing your thumb over the hole, you will feel the air being forced out of the spark plug hole. Stop turning the crankshaft when the TDC timing mark on the crankshaft pulley is directly aligned with the timing mark pointer or the zero mark on the scale.
The valve arrangement is as follows:



E-I-I-E-I-E (right bank-front-to-rear) E-I-E-I-I-E (left bank-front-to-rear)

1. With the engine on the compression stroke, adjust the exhaust valves of cylinders No. 1, 5 & 6 and the intake valves of cylinders No. 1, 2 & 3 by performing the following procedures:
   1. Back out the adjusting nut until lash can be felt at the pushrod.
   2. While rotating the pushrod, turn the adjusting nut inward until all of the lash is removed.
   3. When the play has disappeared, turn the adjusting nut inward 1 3 / 4 additional turns.
   
   
2. Rotate the crankshaft one complete revolution and align the mark on the damper pulley with the 0? mark on the timing plate; the engine is now positioned on the No. 4 firing position. This time the No. 4 cylinder valves remain closed as the timing mark approaches the scale. Adjust the exhaust valves of cylinders No. 2, 3 & 4 and the intake valves of cylinders No. 4, 5 & 6, by performing the following procedures:
   1. Back out the adjusting nut until lash can be felt at the pushrod.
   2. While rotating the pushrod, turn the adjusting nut inward until all of the lash is removed.
   3. When the play has disappeared, turn the adjusting nut inward 1 3 / 4 additional turn.
   
   

Flasher module should be located behind the glove box on connector C203 bolted to the firewall. You may be able to get at it by opening the glove box, and then releasing the stop tab at the top left of the opening to swing the box out of the opening on its hinges.

First, tighten the bolts to 25 ft. lbs. (34 Nm).
Next, tighten the bolts to 45 ft. lbs. (61 Nm).
Finally, tighten the bolts to 65 ft. lbs. (90 Nm).

Did you change the fuel filter? did you put back right?

Chime needs only a ground to work So if that can help try to move the harness and look if chime work normally. If it does then one wire touching the ground on and off (wire touching metal) Hope it helps.

Brake bleeding Procedure 1. First, you have to depress pin location (see Image) Keep this pin block so it will not pop out during the bleeding otherwise air will stay trap inside the system. 2. Start bleeding the Brake cylinder that is the farthest from the Brake master cylinder. Do the 4 wheels in the same matter. Hope it helps.

Could be air in the brake lines. Bleed air from all four wheels and then test.

Plugs are mounted in the cylinder head(s) .Upper most part of the engine. Follow spark plug wire to their location and they are always found on the exhaust side of that head.

The problem is probably a faulty diverter door actuator or vacuum problem at the HVAC plenum under the dash. This is a common problem - see YouTube for help diagnosing this: https://www.youtube.com/watch?v=Nlt9A1sp-4U

where is the fluid leaking from? The transmission or the transfer case? Pretty important to know where it's coming from before asking for help

The only C3500 info I find pertains to pickups and Vans. You need to be very clear about yr, make, model, engine size, 2 or 4 WD. The more info, the better. This is what I see for a 97 Jimmy 4WD.

just get the service and repair manual from the given link and solve all the problem http://toolsnyou.com/

Have you checked the relays?

It sounds like a fan blade is bent and is making contact somewhere , these are usually aluminium and easily pushed back into shape , but if the fan has worn out its bearings it will need to be replaced unless there is some sort of material that has wrapped itself around the fan causing it to jam up .
