The injection pump hydraulic head not only distributes the fuel to each injector, but also opens the injectors. Unfortunatly, tests for the fuel system assumes the engine will start. I would get the stuff to check the HUEI rail pressure, fuel pressure, the IDM can be checked by unplugging the valve cover harnesses once at a time with the truck idling. For supply restriction a vacuum gauge is tee'd into the lift pump inlet hose and should read less than 6 in/Hg at 3300 RPM. Hope your "friend" get's it worked out.

Firing Order On A 8N Ford Tractors

If you still have points, just stick to the solid core wire. The ignition system can be used to troubleshoot many problems. Ignore the problem and it will only get worse. Checking voltage ahead of and after the switch may not reveal a problem.

Cylinders are numbered 1, 2, 3, 4 from front to back and the firing order is 1, 2, 4, 3. Any resistance added by a bad switch makes for a weaker spark. Some suppressor wire measured with an ohmmeter may show very low resistance, but still not perform well on these tractors. If it looks like black or dark grey fiber rope, it is junk.
This may require pulling the movable arm away from the fixed contact if the points didn't stop open. If your tractor starts and seems to idle OK, but does not want to pull a load, check the firing order. The high voltage spark current actually flows on the outermost surface of the core (skin effect).

On a side mount distributor, take the distributor wire loose from the coil, bump engine till points are closed, and measure resistance to ground thru the distributor wire.

8N Ford Tractor Firing Order Of Distributor

In that case, a regular file can be used to remove pits and valleys, before cleaning and polishing with a burnishing tool. This high voltage resistance cannot be measured with a typical ohmmeter.

If there are problems with weak spark or and engine that runs good for a while then starts a random missfire, the ignition switch may be the problem.

If the conductor core looks like cope or stainless steel wire, you are good to go. Spending a bunch of money on high-end wire will not make it run better.
