rough start?

Hi guys im in he market for a jeep and i found one i think is a good deal the only thing that seems to be wrong with it is when you first start it takes a good amount of cranks to start it.When its warmed up it doesnt take as many cranks.I dont know if this is a commen promblem with the jeeps or a easy fix.Its a 97 4.0l 5spd if that helps.Also if there are anything else i sould look for when buying a jeep let me know thanks guys.

Welcome, mine was hard starting for a while. I thought I had a fuel pump issue, it turned out to be a bad battery. It fires right up now. That may not be your problem but sometimes its that easy to fix a problem. Look for a D44 rear end, the D35 has a rubber plug in the fill hole. Also an automatic would be preferred over the manual transmission.

Try priming the fuel pump.

procedure:
Turn the key to on (1 click before crank) wait 3 seconds, turn the key to off, then repeat to on for 3 more seconds, then off again, the last time, turn the key to on wait 2 seconds and try to crank it. If it fires right up, your fuel pump stopper thingy is dead. I dont remember what it was called but once it goes bad, the fuel pump looses pressure so every time you start it, it will have to build up pressure (which takes lots of cranking). This is why once its warm, it fires up because it still has some pressure built up.

It has something to do with the emissions,charcoal canister and the return line.They say that there is a check valve that can be put in the line to stop this problem but I have got used to turning my key on and back off and then fire it up and it starts right up every time I do it that way.Something about the return line lets the fuel pressure leak back off back into the tank and the system gas to be pressurized again to fire right up.

That is mostly personal preference but most say auto because you will more than likely be offroading this Jeep at some point and an auto seems to be the favorite on the rocks and step trails.

If i was to buy another jeep I would pass on the one with a D35 rear end. When buying used there really is no difference in price between one with a D44 and one without.

EDIT: yes the D44 rear end is a much heavier unit. You can run up to 37" tires on it and no C-clips. Its smarter to get it stock on the jeep rather that spend $800 - $1200 later.

An auto trans is fine for city stop and go, but not for off road.

A manual trans and t-case can be shifted into any gear, any time, without having to go into neutral or fiddle around.
A manual can make descending a hill easy, an auto won't hold you back at all.
An auto has that big fragile pan that rocks love to puncture.
Who's ever heard of a manual trans overheating the cooling system?

I have an auto in one of my rigs - I hate it!

rough start

Hard telling what brand of fuel the previous owner was pumping. I'm huge on ONLY using top tier fuels and the top three are Shell,Chevron and Exxon/Mobil.And secondly I would stop your local auto parts store and buy some Lucas Injector additive. Start with that and let us know the outcome.

There's other ways but that is the easiest and 95% accurate.

The only reason why i see a auto is better is because of the torque converter.

With a manual you have to be on that clutch all the time unless you're geared way low.

I'd say a manual tranny with a torque converter is the best just like the old vw bugs.
