Sluggish starts I think. Fires right up when it turns over. Let's see if I can explain it. Lol.
Normal start:
Key turns, chugga chugga, starts
What it does sometimes now:
Key turns, chugga chugga chugga chugga chugga, starts
Very well could be oil on it, the thing is black, and I suspect it's original.
What exactly does the second part mean? Lol. Poor man's prime? Check valve? The check valve on the brake booster?
It's a 99 btw guys forgot to include that.

Okay, so I'm new to the Jeep community. I just purchased a 1990 Jeep cherokee. Ran awesome when I test drove it, started right up, purchased it, went to move it out of my driveway, and it wouldnt start. unfortunately we dont have a lemon law in South Dakota. the headlights, bells and whistles, all that turn on fine, battery is getting roughly 13-14 volts (I'm assuming) but when I turn the key nothing...We thought maybe the starter, so I replaced that yesterday, and still...nothing. I've been reading alot about NSS, and maybe alternator? (not too mechanically inclined) I'm going to check the feed from the starter to the ignition manifold tonight just to make sure, but any help would be appreciated. I bought a lemon, and this sucker needs to run.
My 1990 Cherokee had to be in neutral with slightly pulling back on the shifter toward drive to get it to start.
Could also be the starter relay located right behind the battery.

If its not cranking its most likely going to be the NSS. Try shifting through the gears with foot on brake and trying again. Could also try it in neutral.

Thanks, I'll definitely give that a try to check. I had earlier tried to shift through the gears before seeing if I'd get anything, but nothing happened, and last I tried it in neutral I also got nothing. I seriously think its the NSS, just after putting a brand new starter in there and still nothing, but I'll definitely check out the starter relay.

The check valve, where exactly is it? On the fuel rail? It's a 99.
If it's back there in that box, I'll may try and fix it, wouldn't mind putting a new fuel filter in.

It may be apart of the assembly. The filter is in the gas tank. Not to sure exactly where the check valve is, possibly at the rail
