Residual antifreeze in the gas tank

Yesterday, I was driving my 2001 Jeep Grand Cherokee and ran out of gas. Needing something to fill with gas to bring back to my jeep, I took a gallon container of antifreeze, dumped out ALL of the antifreeze, made sure there was not a drop in it and filled the container half full with gas to bring back with me. When I put the half gallon of gas in my truck and started it, it would not start, was only cranking. Eventually after many tries, it started, drove two miles down the road, then died.

It hasn't started since.

I do believe that antifreeze can screw up combustion in your engine, but I believe it would be several ounces plus, not some residual film of it possibly left on the sides of the container unless I'm mistaken

Anyone have any answers to this problem, solutions?

Thanks!

Add more gas,at least 2-3 gallons and try again.Running dry you could have fried the fuel pump also.

1/2 gallon is nowhere near enough to prime the system and run for very long or very good.

Thanks for your reply.

It seems I've gotten into a bad habit of doing this, 'cause I ran out of gas back in March. Then, I only had a 20 oz water bottle to fill with gas and put in to make it to the gas station. 20 oz was enough to prime and run for about a mile down the road to the gas station believe it or not.

Also, the fuel pump is working still, I can hear the priming whine and hear gas being sucked up.

Going to spray starter fluid in the throttle body tonight, see if it kicks over and is somehow just not getting fuel.

Any other suggestions are greatly appreciated!!

Have you put more gas in it yet? Also try running a fuel system cleaner in your gas. Sometimes when you run dry crud on the bottom of your tank gets sucked up.
