OK. Any thoughts would be appreciated. Have a Ford 3400. I had the head rebuilt after the engine got "drowned" during a heavy rain. Installed the new head, new points, coil, etc. Here's my problem. After going through about a hundred times of regapping points, plugs and bypassing resistor wires, I decided to replace the points with a EI Pertronix distributor system. I have plenty of spark to the plugs but still it won't start. I've removed the carburator and squirted starting fluid direcly into the intake manifold to see if a spark would happen. Cylinder compression is between 70-75 for each cylinder. I've have suction at the intake manifold, and pressure at the exhaust manifold. I do have a slight pressure at the oil dipstick. Any thoughts of what to try next?
 
70-75 is not enough compression, sounds like all the oil is washed out of the rings, try putting a small squirt of oil in each spark plug hole.
 
I'll give that a try. It seems that any compression would at least let the air/fuel mixture enter the cylinder. I'm kind of at a loss of what to do. I've tried just about everything, and a few bucks also. When I had the head off, I douched the cylinder's with PB, but I'll put some oil in it to make syre the rings seal.
 
You say you have "spark", BUT do you have blue spark and with a snap that you can hear? ALSO do you have spark at the RIGHT time? Need all this to fire. Should at lease backfire or fire with 75# of comp.
 
I guess the timing could be off. I've loosend the distributor holddown bolt to rotate it by hand once it fires, but no smoke at all, not even any backfire. After putting on a EI the spark is blue and I can hear a snap. I've tried to open the gap to see if I could create more spark but no luck. I'm running a 40kv, 3ohm coil now, with the resistor wire removed. I'll try putting some oil into the cylinder in the morning, but any suggestions that anyone has would be greatly appreciated.
