Remove the distributor cap and #1 spark plug.  As Gildardo stated, rotating the engine clockwise, bring the #1 cylinder to TDC compression and align the timing marks on the balancer exactly to zero.  The terminal at which the distributor rotor points is #1.  Connect the spark plug wires accordingly.  Take the time to apply a dab of white or yellow paint to mark the #1 cylinder on the cap for future reference.

While you have the distributor cap off take the opportunity to check one more thing.  Before you fasten the cap back down, watch the distributor rotor and slowly rotate the engine counterclockwise.  STOP as soon as the rotor just begins to move!  Look at the timing marks and post the reading.

the wires attach to the distributor cap and spark plugs lol j/k
if you didnt remove the distributor you shouldn't have to find tdc.

An easy way to tell if you are on the compression stroke of the #1 cylinder. Remove the spark plug place your thumb over the hole and when you feel air being pushed out you know you are coming up on the compression stroke,......then stop at the 0 mark on the balancer.

I didn't remove the distributor so is 1 the 1 after the little tongue where you put in the wires like the tach etc? If that doesn't work ill try lining it up to tdc. Do you crank it by hand?

Number 1 could be anywhere, it just depends where it was set up initially. Its easier to set to 0 by cranking it by hand. You can bump it over with the starter until you get close and then finish by hand.

I'm reading this saying wth ??

So your truck won't accelerate is what I'm gathering under load correct? And because of this you replaced your transmission and torque converter  ??? and now you're going to replace the starter ? :o

Totally confused here -

If your problem is acceleration under load you need to check fuel delivery and ensure your exhaust is not restricted.

The transmission was making all kinds of noise and slipping. Fuel delivery is fine and the exhaust is 2 years old with high flow cat and flowmaster. It does this in park and neutral as well. so when the mark on the harmonic balancer is on the 0 mark its at tdc?

It all started when I was going to work one morning. I was going up this big hill cruising, no overheating or anything else out of the norm, when it started to deaccelerate out of nowhere. So I left off on the gas and it slammed back into gear. Made it fine the rest of the way with a few shifting problems. The way back if you revved it past 2k you would hear a zing and nothing would happen. Felt like the transmission was slipping like heck and my max speed was about 25 and to get it to go into second you would have to let off the gas. It died one time and barely started back up kinda backfired a bit. Then it was like that since then.

once upon a time i had a dodge pick up.. yes a dodge... anyways at high speed or uphill there was no power whats so ever... check everything, until i thought about the exhaust... turned out to be a clogged up cat converter... isn´t that something...

Ok so I fixed the spark plug wire dilemma, got it running but the module did not fix the problem. I was revving it up under the hood with the air cleaner off and when you rev it up the carb makes like a vvvv sound when it stops revving at 2k. not the sound of it sucking air though. Truck idles like a dream, totally smooth, no misfiring. this is weird.

Should I try blowing out the fuel filter with the air compressor or just wait to buy a new one? I don't have the money right now to go up and buy one, I know they are cheap. I would bypass the filter (take it off) but don't wanna take a chance on something getting into the float bowl or jets (if there isn't already something in there). dang this California weather, feels like im in the sun outside ha. I appreciate all the help and ideas from you guys. I don't know much about motor internals/diagnostics, just know how to do tune ups and most everything else.  ::)
