So I got this '96 Jeep Cherokee XJ that cranks but doesn't start.  It's got around 180k on her but I keep everything in good shape.  Batt seemed strong.

I used to drive it everyday but this past year I've driven it only about twice a week.  It's been just slightly slower to start in the last couple of months, but just barely slower.  Was guessing it had something to do with aging plugs or something.

Drove it yesterday and everything was normal like always, sat overnight and today it cranked but didn't catch.

Any ideas on where to start?

Try checking your alternator and voltage. What about your fuel injectors and fuel filters. Do you have a 30 bar psi gauge?

Start by  making sure you  have  spark  and fuel pressure to the injectors..

I would guess that your coil is getting moisture inside and that’s why it’s been getting worse.   I would throw a new coil and wires with some new plugs.   Def check fuel as @davefrombc said as well. Maybe a new fuel filter wouldn’t hurt too!

Hey guys. This is a 96 Jeep. Not a quad or snowmobile. The only time to check the carb out that way is 87or older Pre obd 1

How is your compression, any check engine lights?

I don't see anywhere we mentioned anything about a carb.. I  suggested  checking fuel  pressure to the  injectors.  If your fuel pump  isn't delivering adequate pressure either due to a failing pump or plugged  filter   the vehicle will  be  hard starting  and running poor ..  As Frank  said ,  moisture in the coil or  other components of the ignition system  could  cause erratic  spark.

If it is getting fuel  and  spark , then the problem is in timing  or  other mechanical problems.  One thing that is  often  overlooked   is the possibility  of a plugged catalytic converter  causing running problems.

So far I've been able to run a couple tests..

Hooked up a fuel pressure gauge and first key turn got it up to only 20psi. Second turn got it up to 45. And third and subsequent turns got it up to 48. It only fell to 43 after 2 minutes so I think that means the fuel pressure is good.

Hooked up a spark tester between a plug and wire and it didn't light at all when cranked so I'm guessing I've got a spark problem. I'll start by doing a tune up with new rotor, cap, wires and plugs then see what happens.

Good diagnosis. My first guess was fuel but since you got pressure and also found no spark, replace those plugs, wires, cap and rotor to start.

      Hi guys I have a 2003 Arctic 250 4X4 it starts idles and runs great for about 10 min. then it spits and sputters and dies but it starts right up like nothing happened idles good till you give gas and it does it again let off the gas and it's idling great again this goes on for about 15 to 20 min. and then it takes off runs good all day like nothing was wrong.
      I cleaned the carburetor it looked like a new one inside found a little gunk in one orifice, new air filter no crimped lines air line to tank good I did put a meter on the battery idling it said 16.5 V that's high I think would a voltage regulator cause this?
      Suzuki shop wanted to sale me a stator for $556.00 but said it could be something else also thought I'd see what you guys say about it
      Thanks

      Hey everyone, hoping to get some help here... my kids 03 KTF 50 Quad has always ran great... they were riding it a couple of hours a few days ago and it died a couple of times (not normal) but started right back up. A few days later my 5 year old wanted to take it for a spin so I started it (2 pulls) and he took off.. he made it a couple hundred yards and it died and we havnt been able to start it since. I have new gas, good spark and 120 psi compression.. it will not start with starter fluid in the intake or even in the cylinder.. the fuel bowl has fuel at the carb... what am I missing? It’s driving me crazy!!

      Hi all new to the forum I have a Yamaha Moto 4 champ (100cc?) (YFM100) so I've been trying to get this thing to start for awhile honestly I'm running out of ideas so I'll start with the things Ive replaced and done first it was not trying at all and then I put a brand new battery then the terminals broke so I bought some nice copper ones fixed that up so now battery is got good voltage and all that I have checked all the plugs cleaned everything off so anyway it still wasn't trying but I couldn't get the crank case off and I didn't think using fire was a good idea lol so I busted the crank case off on the left side(if you are sitting on it) wierdly enough the flywheel started spinning I thought it was odd but went with it then I replaced the spark plug still wasn't getting spark so I replaced the ignition coil then it was getting spark next the carburetor was really gross I cleaned it out still wasn't working so I in turn decided just to replace it with a new one so I did (PS I never figured out how the fuel lines hook up if someone wants to help with that to lol) also for good measure put a new air filter so then I pressing the button Everytime I replace something and nothing so then I think what if it's the stator so I have no idea what a good or bad stator looks like but me being to rough I broke the wires on the thing but still no changes the fly wheel spins gets compression (I think) getting spark from spark plug idk other tidbits that might be useful I don't have a clutch line so idk if that has something to do with it I do have the break zip tied in to bypass the safety feature also the throttle cable is in fact broken and I'm working on buying a new petcock for my gas tank because my current one is broke I have very limited money this is supposed to be a project before I go to school for welding and automotive tech so I don't have any money to get a mechanic lol but I'm pretty confident in my ability to do anything u suggest any suggestions are welcome I'll edit and submit pics
