i need help

I got a 1990 yj with a 4 cyl. and I was driving it and it overheated and stalled on me. It still cranks over and starts with ether but will not stay running, and there is two relays on the side of the battery that click, I was told that were fuel relay switches so i bought two new ones and they still click rapidly, I already replaced the crankshaft positioning sensor. I have been reading around and people talk about an asd relay on my 1990 i can not find it but my buddy has an 89 and its rite on his firewall. I was just going to buy a fuel pump but it threads say i may waste my money due to it just being some capacitors, if i could just get some insight on what you guys say it would be appreciated. Nobody out here that I know, knows much about jeeps. Thanks

Overheated then stalled, I would start with a compression test. you may have warped the head and blew a gasket. Most likely between cylinder #2&3.

ok so it randomly cranked and kicked over today after work i tried it just to try it and it drove good for 2 miles, maybe a bad fuel connection ? would that cause the fuel relay to click ?

YJ Fuel Filter Replacement

Replace the Fuel Filter located on the Driver's side frame rail about one foot (12 inches) in front of the rear tire. It may have a metal "shield" you'll have to take off first.

It's simple. Here's some Pics:
