93 grand cherokee larado has power, could this be a relay problem?

 

Check your connections at the battery really get tough with them.
I chased a slow/weak cranking problem for a good long time; ohmed out all the cables my meter read that they were okay, SO I bought a replacement starter ONLY to have the same slow/weak start. Somewhere between cussing and screaming at the gods of Jeeps I put jumper cables on the grounds from battery to starter; SHAZZAM starter was working perfectly.
This got me to REALLY inspect connectors, cables and any/everything associated with the electrical under the hood. Finding several wonkie connections and finally getting GOOD grounds I had a '01 that worked!
Funky gauges, engine stutters etc. were gone.
Hope this helps

 

1. This is the Cherokee section. You have a Grand Cherokee. Not the same thing. The Grand Cherokee section is over here.
2. If you want help, you need to make the effort to provide a lot more information. There are no mind readers here.
3. TJ has given excellent advice.

 

If it doesn't do anything what so ever when you turn the key, this is often a neutral start switch problem. (NSS) Try starting it in neutral instead of park, or try running the shifter back and fourth through all the gears several times.

 

 

BlueRidgeMark, I got that bit of advice from YOU/Y'ALL from this site!
I can tell y'all the most important ground is the battery to body ground at the front.
If you have a crappy ground there you'll be chasing gremlins forever. Preachin' to the choir, I know(sorry)

 

Yep. That's why I upgraded mine.

I took the ground screw out, and drilled out the hole to take a 5/16" bolt. Cleaned up the sheet metal all around it down to bare metal. Made a patch about the size of a nickel. Then I fed a stainless 5/16" bolt through from the back side. I used a stainless star washer back there, and plenty of dielectric grease. On the front side, more dielectric grease and another stainless star washer, then a nut. I cinched that down tight. That gave me a 5/16" stud securely fastened to the sheet metal. To that I attached a new custom made cable in 8 gauge going to the on the battery. I gave it all new battery cables at the same time.

 

BlueRidgeMark,
No joking:^^^^ That should be a Sticky!

 

I should post some pics of it before I scrap the vehicle. At least it can help some other folks that way.

 

Yes the jeep gods like to play this little trick every once in a while. Happened to me over the summer
