Starting issue
heres the situation, a friend of mine bought a 90 f150 with a 302 in it. From the start it was having issues. We dig into it and determined that the timing chain had too much slack about 1/2 in movement on the chasing when you squeeze them together. We put everything back together, all the electrical connections, vacuum lines, everything. From the start it didn’t run right and one of the first hinges he replaced was the distributor. Once we got it all back together since we weren’t sure if it was right to begin with I looked online to find something on how to put it back correctly. I will say that we did put the new timing on correctly, lined up the cam with the crankshaft key and made sure the dots were lined up on the timing gears. When putting the distributor back in I lined the rotor up with the number 1 cylinder and started installing the wires from the number 1 on the cap going clockwise. I’ve tried the regular firing order as well as the h.o. Firing order for the hell of it since we weren’t sure if it was the original motor. I’ve also tried starting with the plug wires starting at the spot closest to cylinder 1 for the hell of it. I’ve used a screw driver to check spark from the coil and from the wires themselves and we can’t get it to start. It has fuel, spark and air and for the life of us we can’t figure out the timing. And help or suggestions?

First of all you need to go counter clockwise if you are installing spark plug wires using the firing order. ie the distributor rotor turns counter clockwise.
When changing distributors, it is best not to lose track of which stroke the engine is on unless you have a valve cover off or are good at determining the stroke by sticking a finger in the #1 spark plug hole. ie install the new distributor with the rotor pointing in at least roughly the same direction as the rotor was on the old distributor. Then you can line the timing marks up and check the closeness of the rotor.
