ZJ won't start gets spark and fuel HELP!
Hey guys. My dad and I have been stumped for a little while on this. About a week ago my ZJ's throttle got stuck, then wouldn't start for a while. This was diagnosed to what we thought was a fuel pump because it started with ether then ran for about a week with just the turn of the key. This morning as I pulled out of my driveway, the display "check battery" popped up. Not wanting to get stranded somewhere I pulled back up and shut it off to see if it would start again. It did not. I pulled the battery and had it tested. It was bad so I got a new one with a warranty. Put it in, and it still won't start. It primes fuel to the rail with pressure. I pulled every spark plug and grounded them and it's getting spark. There was fuel on each plug. The distributer is newish and working properly. And now it won't start with starting fluid in the intake. Turns over but won't start up.

I definitely need some suggestions and I'll be checking back frequently for answers. I can post pictures/videos of anything that will help.
