Filter in the tank? I thought they had an inline type filter somewhere? I know my 91 did... but it's a 91.

I'm thinking the check valve is gonna be back there in that "box" by the tank. I know there's no return line off the fuel rail.

 

So... I'll just turn the key a few times in the morning. Lol

Or fix it if my tank starts leaking. I ain't dropping the damn tank for a check valve and a filter.

 

That's usually the final decision.

 

Yea, later year jeeps and alot of vehicle, put the whole assembly in the fuel tank. OEM Chevy ones for my work van is 400-500 for the part

Lol so true

 

installing a head gasket...i have a fel pro... is it ok to install this dry or do i need to coat it with something?

 

Dry.

 

thanks! any loctite on the head bolts other than 11? I have the specs and order...

 

bought a 2000 2dr cherokee with engine light on changed plugs don't know how old they were but were gap at around .75-.80 restarted jeep
after plugs installed started right up next start 3 cranks before turned over. auto zone for codes shot 4 2 oxygen sensors trani speed sensor and maf? now seeking mechanics assistance. oh yeah it has 255,000 on 4.0 driveline is amazingly tight. first post not sure i'm in the right section sorry guys...

 

That's stuff you can easily fix yourself but I hope you only paid $400 for it if even that much.

Also look into doing a radiator flush and check all other fluids. If the spark plug were that bad, no telling how long since and if any routine maintainence was ever done

 

Oxygen sensors are on the exhaust and the MAF is the Mass Airflow sensor, it's on the intake. Like Syc said, all simple stuff to replace. And yes, all are important unless you want 7mpg and a horrible idle.

 

Hopefully the cooling system has been maintained in his '00

 

This is what I'm worried about specially since its a 00'

 

Weeell if the gap was so large, it's plausible that all 4 of those codes are legit, but before you drop any dough on sensors check for wiring problems. Rodent damage and melting can cause that, along with corroded connectors.

DieselD I'm surprised you hadn't heard of that before. It's a weekly feature in this thread lol

 

Lol. Well, if I don't know what people are talking about and it doesn't pertain to me, I tend not to comment and ask questions unless it sounds interesting. Check valves sound boring.

 

lrn2troll. Sheeeesh.
