Engine Stalling

Well, I bought a vacuum gage. They didn't have anything with a handle. They had a gage with different fittings that can check vacuum and compression.

So, my indications when I hooked it into the line I fixed the vacuum leak on (connected to the purge solenoid and the throttle body) were this:
Initially, vacuum comes up to the middle of the green band (18/19 inches) and is steady. Once purge solenoid starts clicking, vacuum drops to the bottom of the green band (15/16 inches). Then right before the engine stalls, the vacuum goes away.

Looking closer at the purge solenoid and the fuel system, all this may be a fuel problem. I just don't understand why it would tend to stall more when I come off the gas or am at idle for a bit.

Talking to my wife, the shipping company tried to start the Jeep over and over for about a half hour before they finally put gas in it. After that, it started right up. So, it was out of gas and the fuel pump comes on every time the key is turned to the on/start position - which was a bunch of times over the half hour.

I'm thinking about dropping the gas tank and taking a look. Before I do, I want to figure out if it's possible to have a fuel pump problem with no fuel pump codes.

I'll be looking at the Jeep more again this coming week.

Thanks again for your help and patience. If you've had any epiphany's, please let me know. Thanks, Jason

My vehicle kept shutting off after the towing comp. Came out 3 time to charge my battery.

Maybe the batter died. However I took it to Good Year and the mechanic said I need a new battery that would cost me 129.00, and I needed a new Radiator. He said at some point the car got hot and the radiator cracked and has been leaking water.

The hot/cold gage always remained in the middle of the gage, and I never notice the car getting hot, since I got a new water pump in June 2009.

They are charging me an additonal 750.00 for this water heater.

Can you diagnose this situation, are they just taking me for granted because we are in a recession.

Please reply: Broke

My Jeep will start but runs very rough. It shakes and runs as if some cylinders are not firing. I took the gas tank off and cleaned it out as there was some foreign liquid at the bottom of tank. I took it to a mechanic and he checked the fuel pressure and it holds at 50-53. It still shakes and acts as if the cylinders are not firing, they are (mechanic checked), and after a little while it dies and I have to wait about an hour to restart it. The mechanic thinks it might be the pcm. Any suggestions before I dish out the money? Any help is greatly appreciated, Thanks

I have a Jeep liberty that stalls when it reaches temperature and gets progressively worse. While it is running at speed it is fine besides the fact it seems as if it isn't running on all cylinders or there is a blockage of fuel delivery. I've replaced the air intake manifold, I've seen some articles about possibly having a valve spring issue. I'm at a loss any help would be appreciated greatly. I'll list symptoms:

Starts fine and runs fine while cold

When it reaches temp it begins to idle rough and eventually shuts down if idling long enough

it has trouble accelerating especially over 3000 RPM's

The check engine light is on and occaisionally blinks.

I have been told it could be catalytic convertor, valve springs, head gasket, etc, etc, but none of the above shops have been able to pinpoint the issue.
