85 22R no start!!!
I picked up a non running pickup recently and I cannot get it to start.
It is a 1985 22R 4X4 with a 5 speed transmission.
It cranks but will not start and no spark.
I have power to the coil.
I have .7 ohms resistance between the + & - on the coil.
Is there any other checks on the coil I need to do?
How do I check the distributer and the igniter?
Also I cannot get fuel to come out of the tank through the supply line. I can sprinkle a little fuel into the carburator and it will run for a few seconds. I really do not want to drop my tank, ughhh...
Edited to add that this is an intermitant problem now. I had spark this morning while trying to start this truck. Now I do not, same problem as yesterday.
Is there some kind of circuit in the igniter or distributer that cuts off the spark if the starter is cranked to much?
Thank you, Phessor

did you try doing the same with the coil wire? or just the plug wires? When I test for spark I usually take the plug out keep it on the wires and ground the electrode, but I guess you way would work too.

yeah but I never tried doing it with the coil wire. Don't even know if it would even work for that. But checking the coil wire is really just ruling out a problem with the distributor.
oh and please don't think I was being rude by my first question, but I have seen people say they have nor spark because they either assume if they have fuel they have no spark and not even check it.

thankfully, I have had no major electrical issues on mine as of yet other than a POS choke on my original aisin carb, which is why a weber is now on it. lol. But stuff is a heck of alot easier to diagnose then on a 22re. Like a no spark issue or no fuel issue. Or erratic idles.
At least this guy did some of his homework and knows he's getting power to the coil and not out of the plug.

looking more into the whole spark plug in the coil wire trick and guess what I found keep in mind this guy is working on a 944 Porsche, ignore the wire colors !!!:

Ignition Coil Test
1. Disconnect the ignition coil output wire at the distributor cap.
2. Connect a spark plug to the end of the ignition coil output wire which you just disconnected.
3. Connect a ground wire to the threaded portion of the spark plug.
4. Disconnect the ignition coil ground wire from the negative terminal on the coil (Green Wire).
5. Connect one end of a ground wire to the ignition coil negative terminal.
6. Turn the ignition switch to the ON position.
7. Tap the other end of the ignition coil ground wire jumper on an good grounding point (for example the battery negative terminal) and look for sparks at the spark plug that correspond to the frequency of your tapping of the ground wire.
8. If you have a good spark at the spark plug, the ignition coil is good.
9. If you don't get a good spark, check for approximately 12 VDC from the coil positive terminal (black wire) to ground with the ignition switch in the ON position. You should also get approximately 12 VDC from the coil negative terminal (Green wire) to ground
