Hello the location of number one cylinder as long as the distributor has never been tampered with is going to be, As if you are standing at the front of the engine, it will be located at about 5:30. If it has ever been moved then you will need to pull #1 spark plug (driver side front). and put a screw driver in the plug hole at the same time have someone manually turn engine over( not with Key)
but by the crank shaft when you feel the(you must also beable to feel airbuilding up)on the compression stroke, piston all the way up remove distributor cap and look at the button direction. There you will know that is #1.

1993 chevy suburbun 5.7 liter, edelbrock high output fuel injection has fuel and spark still wont start have changed distributor, coil,cap and rotor, plugs and wires are fairly new, timing is dead on,...

When you changed the distributor did it go in the right way sometimes people put it in 180 degrees around as it will drop right in then also take a look at the rotors position when you are at the proper firing position for 1 and check it otherwise it seems like a walk down as in going backwards on all your steps to see if its right

Hello, my 1989 chevy dually 3500 v8 wont start. Distributor was loose moving around

Gasoline I assume?? The timing is probably way off. Using the mark on the harmonic balancer and set to 0. Rotate the distributor so that the rotor is touching the #1 cylinder. Try to start vehicle, if starts, then use a timing light and set to spec by rotating distributor in very small increments. Tighten distributor. A service manual will help and they run ~$20 at any parts store.

Automatic transmission dropping out of overdrive/4th gear

Likely you have a shaft seal or clutch piston seal thats leaking only when the unit gets hot and clearances change. It will require teardown and careful inspection to determine exactly where, then replace worn parts and finish rebuild.
