Heys guys new here and hoping for some help.i have a 97 jimmy 4x4 .shut down on me the other day n been fighting with it since. I had some front end work done on it and after that it shut down driving then picked right back up then later i turned it off n would crank but not start. Fuel pump wasnt workin. Tested pump its fine. Checked relays in glove box they were fine but not clicking when i turn on the key. Heres what i dont understand. I was sittin in the truck not moving or touching anything but had the key in the on position when suddenly i heard theon fuel relay click. Hit the key and it fired up. Let it run a bit then turned it off and wouldnt start all dayn n no click to the relay. Then accidentally left the key on for an hour hit the key fired up ran great then died after a minute n wouldnt start.i checked ground to everything with ohm meter all seems good. If i cant fix it quick i gotta shop it but would rather do it myself cause i know it has to be something simple im missing. Any ideas?
 
could possibly be a bad relay, they aren't really known to go bad but when they do they act up like that, i can suggest is back probing the power wire to see if u have power to the relay, if ur positive that the ground is good,

a relay will go bad it signs are that, it'll work sometimes cause if u leave it on for long enough it'll heat up if it makes a connection and work that one time.

there is a way to check if the relay is bad but it depends on if ur willin to give it a shot
