I have had hesitation problem with my vehicle. Now there is charcoal pebbles getting blown back through the vacuum line into the vacuum pump and possibly into the intake. Could you give me the location and a picture of evaporator canister? I am pretty sure that is what is doing this. I will replace canister and all vacuum lines associated with it.
Do you
have the same problem?

We don't' have a pic of that location. But it should be along the frame by the gas tank.

I checked and tested charcoal canister. It seems to be fine. I'm still getting tiny bits of charcoal in vacuum pump and possibly in throttle body. What could cause this? Would it be the EGR valve solenoid? A vacuum line goes from it to the charcoal canister

I'd say the canister more than anything are you sure it's charcoal and not burnt fuel/oil? Take canister and shake it if you can if you hear stuff moving it's getting sucked into system. Or broken inside.

My 1995 chevy s10 had a faulty ignition control module so I changed it. Then fuel pump went out so I changed it. I tested it for fire/spark. It has yellow spark not blue or orange. Could this be caused by faulty coil packs?

Scan for codes first it may be something else causing it other than coil paks. Besides I think your has only one coil pak

I tried with a paper clip. The dash light is burnt. So I can't tell. I changed coil packs. It's firing bright orange now but still not starting. I changed ignition control module, fuel pump and coil packs. Both coil packs. I have a spare computer for it so I tried swapping it just to see. It's still doing the same thing

If you can't read the codes you will probably never find what is wrong with it. check fuel pressure with a gauge as well auto parts rent it. try a spare key if you have one that may be problem. not a new key.

I changed ignition control module, coil packs, plugs and wires along with crankshaft position sensor. The engine turns over fine but still doesn't start. As I attempted to start engine it backfired and a cloud of white smoke came out of what appeared to be under the truck. I can't say where it came from. The hood was open and I didn't see any smoke coming from the engine itself. Please help me with this.

The spark plugs are all gapped properly. I went over them three times to make sure everything was correct before attempting to start the engine

Check the map sensor a lot of times these cause it or a vacuum leak or soft hoses. Also check engine coolant temp sensor. It may be out of time too.

I just purchased a 1996 Isuzu rodeo with a 5 speed manual transmission. It has a 4 cylinder engine with 285000 miles. I drove it home but had a hard time shifting the gears. Now it won't even go into any gear. I tried to bleed the clutch better than it was but it still does the same thing. Tried putting in reverse all it does is grind the gears. Is there an adjustment cable for clutch on this model? Or could it be internal?

It sounds like a clutch problem and in future post this question as I normally don't answer posts like yours on a different model. There is no adjustment as it's hydraulic. See pic for bleed instrucionts.

I recently purchased a 1996 Isuzu rodeo with a 4 cylinder engine and manual 5 speed transmission. The gear shift has a curve to it. The curve is facing to the front of the vehicle. I have a hard time putting it in gear to take off and it shifts pretty rough. No grinding or anything but still shifts rough. Is the gear shift backwards or is it a clutch problem?

Bobagurl it sounds like a clutch there is no adjustment to it so check for a hydraulic problem like air in system. In future post this question not an add on as they generally dont' get answered.
