Fuel/Starting Problem

I have a 78 CJ7 Golden Eagle with the 304 that I bought from a man about a year ago. He had put a new battery, distributor, plugs, wires, filters etc on it. I drove it for a few months then had the jeep body work done last winter. Got it out of the body shop and drove it a few weeks. I had recently had the timing set but it was still having problems missing. I assumed trash in the carb or fuel tank as it had sat a while. While driving down a back road about 35 it spit and sputtered and quit. I could not get it to restart and while cranking on it it would puff vapors from the carb and on certain rotations the motor would lock down until I let it sit a moment. When loading it on the trailer liquid fuel (I assume) flowed out of the exhaust. I'm assuming a quart at most. I have let it sit up a while and now have started piddling with it again. The plugs wires are getting fire (the two I checked) and it sputtered once but will not start. Any suggestions on where to start? I recently bought an Auto Parts store so Im ready to get some things replaced and get it up and running for the fall.

A quart of fuel would be a LOT.

Could it have been water???? If water, did it look like coolant or rain water?

It could be that you have a major water leak. Have you checked the collant level?

Have you checked to make sure your fuel pump is getting fuel? Do you have a fuel filter with 2 hoses coming out, 1 going to carb and 1 to the gas tank? If so, do you have the line going to the tank on top of the line going to the carb?

I would also check the plug wires to make sure they aren't accidentally crossed and they are all tight

1. Fuel - Confirm fuel is getting to the carb.

2. Air - Confirm the choke is functioning properly.

3. Spark - Confirm you have spark at the plugs while cranking.

I my memory serves I went back and looked and it was defiantly fuel....however, I was having some problems with it getting hot before I parked it and looking in the radiator yesterday it appears I have lost some coolant....I'll examine it more today....

I pulled the fuel filter, which does have three lines, and it was bone dry.

Pull the oil dip stick and look for signs of fuel or water. Pull the radiator cap off and check for oil in the coolant.

Beat it to fit, paint it to match!

Pull the fuel line off of the carb and have someone crank it over while you watch to see if you have a good stream of fuel coming from the fuel pump.
