Setting timing in 1996 305 Chevy truck

I've uploaded a diagram that gives you the firing order for the 96 Chevy Cheyenne. The best way to find out which is number one in the firing order is to following the spark plug on the engine block back to the distributor cap. Number 1 is on the right side, closest to the front of the engine. Best of luck!

Sounlike the pickup module in the HEI distributor is not working . Check the red wire for power and a good connection

Without knowing if you have a V6 or a V8 motor I can't look up your TDC for your '86 Camaro, and if you don't have a timing gun that knowledge wouldn't help much anyway. However, you can tune your engine by ear and it may help the sluggishness. To do this mark the block and the distributor so you know how far you are advancing your timing once you start adjusting it. There is usually one bolt mounting the distributor into the block, loosen it until you can turn the distributor but it is still stiff enough to hold in place while the motor is running. Keep it in its original location and start the motor. Carefully, with a warm engine, gently turn the distributor ever so slightly clockwise until the engine isn't shuddering and is idling smoothly. It may take some trial and error to find the right spot. When you are confident your engine sounds right turn off the motor and tighten the bolt. Make a mental note of where you relocated the distributor to in relation to your other marks on the mount and the block. Then take the car out for a test drive. It may feel sluggish by too far advancing or retarding the timing. If so try again using the original marks as a reference. If this doesn't work, put your distributor back to its original location before troubleshooting further.

No, but you should disconnect the vacuum hose from the distributor and clog it while setting the timing if it has a vaccum advance

Man your best bet would be to take it to good Toyota mechanic! When it jumps time their hard enough to get back on!

Engine distributor out of time,,,with crank ,or the cam has jumped time from the crank shaft,, maybe 1 tooth

What do you mean? Its either in time or its not. Why are you checking the timing? You turn the dist to get the timing right. Give some history about the complete problem and what you have tried to do to fix it.

Distributor get taken out? Sounds like it's one tooth off at the gear between the camshaft and the distributor shaft.

Turn the engine by hand till the timing mark on the pulley is aligned with 0 on the timing scale (right side of pulley) If the rotor is pointing at the rear of the engine, turn one more time...it is now pointing at #1.
cylinders are 1,3,5,7 on drivers side, 2,4,6,8 on passenger side (front to back) Order is 18436572.

a lot of shops don't check base timing on the distributor. it could be the timing is set too low, or the module is not advancing{inside distributor} or another comon problem is a tear in the fuel pressure regulator. so pressure is too high all the time.
