Jeep - Cherokee :: Lack Of Fuel Pressure - Sputters At Start Up / Dies Silently While Driving
Jul 9, 2013
I purchased a 1990 Jeep Cherokee Laredo at a steal . . . I've already replaced the head gasket sealant. My biggest current concern is the fuel pressure. The car either starts up beautifully or sputters and gurgles for a good 5 seconds before finally idling normally (either occur during cold or warm starts).
The sputtering at start-up has become more commonplace as of late. If I drive away without providing a good three-to-five minute warm-up, the car will drive as normal while applying gas pressure to the peddle, then once gas pressure is no longer applied, the car dies silently; The battery stays on, but all power steering and engine power disappear and the car coast into nothingness. If I allow the Jeep to warm up significantly, it will drive as normal for hours, except for it's struggles to compensate long upward hills.
The fuel regulator has a slight leak. Worse at start-up, lessens up over time. The seal may be improperly seated, but is in physical working condition as I can tell. Spark plugs were replaced. Battery was replaced. Injectors have been tightened. There is a slight oil leak (it seems to move around a bit), but is far better since the Head Gasket was replaced. Could this be a bad fuel regulator or something else that I have missed?

I have a 1987 jeep cherokee with inline 6 and multi port injection.
Sometimes this vehicle only starts when hot
Some times only when it cold
I have recently fixed the fuel leak.
When its hot or cold and not starting if i relieve the fuel pressure at the fuel rail, in most cases it will start immediately. However if fuel pressure relief does not work. I disconnect the vacuum line at the what looks to be the EGR valve or the pressure regulator at the front end of the rail, then usually starts right away.
I have not tested at this time to see if the fuel pump is failing nor have i tested fuel pressure. I am trying to narrow down the problem to one specific part. There is no problems with cranking. There is spark - coil, plug, dist cap have been replaced.
It seems the problem is with fuel delivery of sorts. It was mentioned that sometimes the heat from the engine could be heating the fuel rail to a point which turns the fuel into a gas not allowing it to atomize.

My jeep is having two issues. First, almost every time I start the vehicle it idles fine, but then when I start to accelerate it bogs down for 1 to 2 seconds. I will accelerate through it and after that it runs fine and doesn't do it again until the next time I start the vehicle. My second issue is that after driving for a couple of hours with the AC on, the flow of air out of the vents drops. The air is still cold to the touch just barely blowing. Once I cut the motor off for about 30 minutes it works fine again for a couple more hours. Also, when the intensity of the air coming out of the vents dies down the blower motor sounds like it is working harder to put out the little bit of air pressure.

95 jeep cherokee. My oil pressure gauge sometimes jumps up to 80lbs or bobs between 40 and 80lbs. Could this be anything other than sensor or gauge itself?

I have a 1998 Jeep Cherokee L6 4.0 Liter automatic with 223,000 miles.
The oil pressure usually runs around 1/8-1/4 when driving around town and now I am getting temperature spikes. I had the coolant and water pump replaced last fall when I was having similar idling issues then. My coolant isn't a perfect green color--it is a little bit grey, but it is full. I cleaned the entire throttle body last January, cleaned the IAC today, and redid the NSS this week (not that this probably matters, just being thorough in my explanation).
It seems to happen worst on hot days (of course) when idling in traffic for a few minutes and makes the air conditioned air run warmer than it should.
Is this a busted radiator? The mechanic said I did not have a leak when I had him check last week.

I have a 1999 Jeep Cherokee Sport with 140K + and recently had an oil change. I went on a 8 hr road trip split up between 2 days (there and back). On the way home I noticed my oil pressure gauge acting funny, going up and down but not past 40. Today, I drove home from work (10 miles or so) and the check engine light came on and the oil pressure gauge was very low, almost 0. I made it home but was very nervous and noticed both today and this weekend there was smell, burning or burned type smell. What should I do? I don't really trust the garage that changed the oil and was skeptical taking it there but was in a pinch.

I have a 4.0 6 cyl. Jeep wrangler manual transmission. When the jeep is driven in higher RPM close to redline the jeep sputters a bit (doesn't have full power at or close to redline). Is this a governor or does the jeep have a problem? I do not redline often at all. however i live in the mountains and need to travel up steep pass for 1-2 miles every few months.

'95 Jeep Grand Cherokee Laredo 4x4 (bought used 3 years ago), The Jeep sometimes dies while we are driving it. Most of the time we can restart it right away, but others it will make the turning over sound and not "catch" & go vroom.
Other times we'll be driving down the freeway (for example) and it will do a little shutter, like it's going to die and if we push on the gas it kinda skips over the dying part.
We thought it was the fuel pump, so my father-in-law took it to a mechanic and he checked it out and said the fuel pump is fine. His assistant drove it around for a while & it never died on the (of course). So he said it was fine and suggested we got some bad fuel and told us to put in some Chevron, but later that night we drove it close to home for 20min & it worked just fine. Ate some dinner at Mom & Dad's then it wouldn't start up again.
We've changed the Fuel Filter, it has a new Radiator, New Brakes and Just got an Oil Change, we filled it up with Regular Chevron and added 'HEAT' (additive to get rid of moisture)... We are at a loss...

I have a 93 grand cher with 194,000 miles on it. I have never had a problem until now. When driving the jeep sometimes it stalls and then starts back up again and you keep driving. Or othertimes it stalls when you are stopped and you need to start it back up. I had it at 2 dealerships but they can not find anything wrong because it is an intermittent problem and never happens when they have it.

So i have a 1999 Jeep Grand Cherokee Laredo, 4.7L v8 , it has been running good until as of lately. It has stalled or died on me 3 times, I can usually drive it for about 20 minutes, or travel short distances before it stalls out on me, the stalling is completely random, any speed/RPM. I have read everything under the sun about what could be wrong here, but where to start, have been hearing a lot about new Crankshaft sensors, TPS's , etc...

I have a 95 Volvo 850 2.2 L (non-turbo.) I recently replaced the fuel pump, and filter. Now when I try to start the engine, it turns over and sputters before it dies. I let it sit for about 10 minutes and try again with the same results and the same with a longer wait time due to having to charge my battery. I have checked the fuel lines and they seem to be clear, up to the fuel rail. I also checked the plugs and although they need to be replaced, after sanding and re-gaping them, there is plenty of spark. The plug wires and distributor cap are fairly new, and the points look good. So the only problem I see as logical, is the fuel rail, pressure regulator, and injectors. I have bled the fuel rail at the shrader valve, and I am getting little to no fuel from it. I want to remove the injectors and rail, and check out the regulator along with the rest. But how do I tell if the regulator is good, and what is the best way to clean injectors so they will at least last till I can replace them with new?

I have a 97 Jeep Cherokee with a 4.0 V6, fuel injected, 4 wheel drive with a 5 speed. It has developed a stuttering or a hesitation at times while driving. It's hard to describe, but feels like the engine is not getting fuel or air at short quick bursts, thus a stuttering feel.
Some things I've noticed: It happens mostly when the engine is cold, but can happen any time.It seems to be worst during rain or snow.At low throttle, it can cause the whole vehicle to shudder violently and at full throttle (gas pedal down for acceleration) it is very noticeable but doesn't seem to cause the vehicle to shudder as hard. I think I hear a metallic pop or clack when it happens, especially at high throttle. It doesn't seem to matter what gear I'm in.It doesn't matter whether I'm on a flat or a hill. It doesn't seem to matter what speed I'm going, but it is a little harder to notice cruising along at 65.
Maintenance History: The vehicle has had several things replaced in 2011: Alternator, crank position sensor, relay on the ASD, serpentine belt, spark plugs, plug wires, cap and rotor, battery, engine compartment fan.
The vehicle went into the shop when it started dying at stop lights or stop signs and starting hard. The diagnosis was the crank position sensor and that did indeed seem to fix that problem. Within a few days, however, the vehicle started running rough and would come close to stalling when idling at a stop. My mechanic sprayed a bunch of cleaner down into the air intake part of the engine (a part that reminded me of the butterfly valve on a small carburetor). The problem went away, but this stuttering problem started up about a day later.

I have a 1999 Jeep Cherokee Sport v6. I have replaced the fuel pump, fuel filter, Battery, cables, alternator, distributor cab, and plugs and my car keeps stalling out on me. It drives and idles just fine but when I am driving or accelerating the vehicle dies, I let up off the gas and it restarts itself. When I hook it up it does not read an error code!! Not sure what to do next.

My inline 6 engine softly stutters and misfires while driving and has the check engine light on whenever this happens. It's becoming more frequent now - 20% of the time I'm driving I'd say. The codes are 11, 12, 27, 34. I've looked up the meanings of the codes and I'm leaning towards its bad fuel injectors or a bad connector leading to the fuel rail. I have lots of bad wiring on my 93 Cherokee haha. I've fixed so far: a bad head light connector, and an exposed wire that connects to my distributor - it would swing and touch my engine block causing the engine to die.
But now I am struggling on how to fix my small stuttering engine problem. So the problem only occurs after I make a strong left hand turn such as a 90 degree or a uturn so that means a connection is being pulled to the right. It doesn't have an issue turning to the right though. I don't have sway bars on my 6" lift so there's a reasonable amount of body roll to pull on the wires etc. When I open the hood with the engine running smoothly I can touch and wiggle the front fuel injectors and sometimes I hear it softly misfire or sputter. What connectors lead up to the fuel rail?

I have had no problems out of my jeep except my check engine light came on and it was a bad 02 Sensor and I was told I didn't need to replace it. Well I was driving down the highway and all of a sudden my jeep died. The radio cut off my air and I put it in neutral and I tried to start it and it would not crank. I coasted in a drive way and it cranked and them died. Now it acts like it wants to start but it wont. Replaced the fuel filter. I am getting fuel to the fuel rail. It will not start with starter fluid. I took the crank sensor off and it replaced it and it still wouldn't crank. My fuel pump makes a whinning sound. My lights come on..My windshield wipers won't. My radio doesn't work and the inside lights well I couldn't get them to go off before I before my vehicle died on me, about 3 weeks before I just took the bulbs out. Would the 02 sensor make it not start?

I've had this car for a little over a month, when I first bought the car it ran fine, until I drove it home. It stalled out and would not start up again, turned out I had low fuel pressure so I replaced the fuel pump. After this the car had been running fine up until a few days ago. It was stalling out and starting right up, now I am lucky if it will start up. I am still getting fuel pressure to the fuel rail. Would it be my injectors?

I currently have a 1997 jeep grand cherokee that I seems to die on me. I will charge the battery to 100 percent and its actually a good battery. The vehicle will run fine and then out of nowhere it wont start. I throw the battery jump box on it and it starts. I was thinking that something has been obviously drawing power from the battery. What it could be?

My 98 cherokee sport(xj) 190k has always been reliable but now its hard to start. I must press on the gas pedal and rev it up so it doesn't die. Never has done this, after a few revs it seems find. Is my fuel pump bad.?

This past week when I went to leave work my jeep would not start. It would turn over once, and then die....but if I kept my foot on the gas and kept the RPM's up it stayed running. So, I drove it home with one foot on the gas and one on the brake so it wouldn't stall out on the road. The next 2 days the same thing happened when I went to leave work. It starts fine the rest of the time, even first thing in the morning when it's cold..
