I have a 1997 Jeep Cherokee Sport SE, 4 door, 4.0L v6

It won't start, it'll turn over but that's it. I just bought a brand new battery and it still won't work so that's not the problem.

It worked fine the day before but I went to turn it on in the morning and it wouldn't start. And my Jeep is kept in my heated garage every night too so it wasn't the weather.

I can start to smell gas when trying to turn it on especially when I open the hood. Not sure what that means those.


Any help is appreciated, thanks.

I'm not a car guru so a little more explanation would be helpful lol. Sorry.

lol, its ok

The coil is what sends spark to your spark plugs. They can and do randomly die. Pretty easy to replace.

There is a pickup of some sort in the distributer that can go bad...should be easy to replace also.

These would be where i would start if it was me

Alright, I'll check that out tomorrow. I'm making a list of possible problems. Other things I have written down to check is: Fuel, air filter, compression, spark plugs, and crankshaft position sensor.

crankshaft sensor is the only one out of there that would make it just stop running one day. Maybe, and just MAYBE the fuel filter.

Alright thanks bro. I'll see what I figure out tomorrow after school.

no problem. I doubt youll be able to tell if most of those things are bad by looking at them. I mean, if they have broken wires you will be able to.

The spark plugs were getting spark but I don't think enough. They sparked like every 1.5 seconds when i was cracking it over. I think it should spark faster than that.

I just towed it up to the local car mechanic and I'm going to see what he says. But he said it'd probably be Monday before he looks at it.

Im going to say its most likely a spark issue. Try that first

distributor cap & rotor, fuel pump, check your major fuses & relays

That spit sputter spark you see when you are cranking it over is going to be some what normal. Your not going to get a good spark(well constant) from it because its not up and running. What kind of spark tester were you using. Also were did you test it.

Pulling that cap off and check the cap and rotor you could of done yourself very very easy to do on a jeep 4.0 motor.

My next thing is you say you can smell fuel under the hood. Its fuel injected you shouldnt smell fuel at all under the hood unless you have a leak some place. Could very well cause a no start.

When you were sitting in your jeep cranking it. Did you happen to look at the RPM gauge did it go up from zero when you were trying to crank it. Or did it just stay at zero the whole time you were cranking it.

All I did to test the spark was take off the cover for spark plug # 6, I believe, and stick a screwdriver in there and laid it across something that was grounded.

I believe the RPMs sat at 0. Can remember that well.

Hmm...makes me wana say its the lil magnetic pickup in the distributer. I forget what theyre called on the jeeps...

and could you here the fuel pump turn on? its uncommon for them to just die. But it is possible

Its a cap and rotor type. What you and others are thinking of is a tad bit older in age, years. This type the rotor sits on a shaft and spins around sending spark to each spark plug through the cap from the coil.




Now saying you think you seen the RPMs just sit at zero while you were cranking it. Says crank signal. Crank position sensor do go bad on the jeeps all the time. And will give you a weak spark while cranking. That sensor sits on top on the bell housing area. Near the steering shaft.

Alright thanks. The local mechanic is going to look at it monday. I've told him everything that has been said here. Hopefully it isn't expensive.

I hear about this a lot on jeeps. I would first look here really.

my best guess is crank sensor, and the whole sparking thing being not often... makes perfect sense, not all plugs spark at the same time..

It was the fuel pump.

It cost $372.06 to fix. wtf

Is that right?

Want to say fuel pump for my s10 was ~$125 for the part... so thats probably about right for parts and labor. Should have done it yourself....

Bologna

It was $269.99 for the part and $82.50 for the labor.

its possible. Remember the mechanic has a mark up on all parts sold through them...

Bologna

Well I just found the exact same part for 199.99 at both autozone and advanced auto parts. Those are the only 2 auto parts stores within 40 miles of me.

so do it urself and save $75 or have him do it for $75, thats basically what he is charging u

or u can ask if u buy the part locally what will he charge ya

Holy **** man. That's insane. I've gotten qoutes from people for 400 bucks for a fuel pump. Then went online to find the motor for 99 bucks. The just swapped motors. That's nuts.

So, the mark up on the part was less than $70.... not too bad actually.

Bologna

You think that's fine? I disagree. They should charge for labor, not for the part plus $70. That's a 35% mark up..

This is just a local business, not a huge corporation. My town is only about 900. I know everyone that works there on a personal level.

I still think it's overcharged.

they are a business, they sell a part, they mark up the price of said part. Simple as that... Is it "fair", yes. They have to make money to run a business. You're $80 labor charge just paid the guy that put it in. Wheres the money for over head come from if they dont mark up the part?

I guess that's right. $20 tax too :(

Thats the world we live in. If ya cant Do-it-Yourself, you're open game for those that can do it. This means you pay what they charge. Thats why I always try to go the DIY route if at all possible.

Just Empty Every Pocket.
Everything to fix on my jeep was expensive. I finally gave up and sold it for a huge loss. Not sad that it is gone sorry to say.

Fuel pump ??? really. What happen you smelling fuel under the hood. Ehh..

I know the price is high but think too. They may add things in there too. I know at my shop we replaced lines and fuel filter at all times doing a fuel pump replacement. Always clamps. It was just prevent maintence( how ever you spell it).

Although price does sound high. But then again prices are jumping up for older vehicle parts.

I had no real problems with either of my jeeps. They where/are cheap to fix and took no time to fix either. Your problem is that your not a mechanic. Shops charge different prices all over the place. Prices of parts are all over the place too.I price shop for things soooo much now days its not even funny any more.

Case in point I was looking for lifters for my dodge truck. Prices for the same lifter. Same model number, part number, brand. I found the price went from 9.95(what I got them for) To 23.50. Per lifter.
