2008 Jeep Liberty Fuel Relay Switch location.

My 2008 Jeep Liberty limited randomly doesn’t start. It doesn’t do it all the time. It seems when the weather is warmer and I run multiple errands and start and stop it multiple times it won’t start. The engine turns over but it doesn’t start. When I let it sit about 30 mins then it will start again. I was told it could be the fuel relay switch or fuel pump fuse but probably not the fuel pump. My mechanic is having a hard time locating the fuel relay. Where is it located? Any ideas what else it could be? It runs great otherwise.

Sorry ,but you need a better mechanic . This wouldn't be the relay .if it was the relay it would do it all the time . Hooking up a professional scan tool an checking sensor input data to the PCM- engine computer is what should be done . What are the fuel trims at ? short & long trims , are the O2 sensors switching normally , what's the mass airflow sensor data ? any codes stored . It just so happens the relay on your vehicle is a PCB relay . Printed circuit board relay . Which means it's inside the under hood fuse , soldered to the circuit board . Do yourself a favor an take it to a qualified repair shop.

SOURCE: Ford Escort 1998 fuel pump not working.

good old ford lol, try looking at the crank sensor its located at the front of the engine tucked in right hand side of exhaust manifold and gearbox, two pin plug, i have also known these to have no end of faults with the fusebox.
easy to remove, and solder the connections inside they all suffer eventually, if your not to handy with cars i recommend taking to a auto electrician, easy if you know how. Good luck Davelee

SOURCE: My 1994 suburban engine stops. No fuel, no MIL light.

I checked all of the fuseable links and they were all good. Next I decided to check all the power wires to the ECM and also the grounds from a wiring diagram because the Mil is controlled by the ecm and the bulb was good. The ecm is located behind the glove box. Bingo, the orange wire was only reading 3-5 volts at the ECM, but 12.5 volts after the fuseable link at the underhood fuse block (passenger side firewall). I ran a temp wire directly from after the fuseable link to the orange wire at the ecm and the ecm turned back on and the Mil or "check engine soon" light came on too. The truck started up and has never run smoother.

Note that at first the truck just stalled out and I could restart it right away with no error codes. Eventually the stalling became more frequent with longer reset times required. Once it threw a "code 54" and I thought it was fuel related as each time the gas stopped and I could still start the truck with gas poured into the TB. Ignition ok. My fuel pump turned on and ran if I tested it. I even checked the pressure regulator and the fuel filter to no avail.The orange wire that powers up the ecm is technically part or the fuel pump relay circuit as it also feeds the fuel pump relay 12.5 volts all the time. The thin orange wire from the fuse block is joined to two other thin orange wires in the large group of wires that heads to the ecm along the firewall behind the engine. I had to dig it out of the many wires to find it and remove a lot of tape. It is amazing to me that this one little orange wire could cause so much grief and be so hard to track down. I could not have afforded to take this problem to the Dealer.

SOURCE: 1997 Neon dies, starts after electric fuel pump relay swapped

Hello, I would assume this is your fuel pump inside your tank. I would first however do some basics like a general tuneup. For starters I would replace your spark plugs and wires, rotary cap and button and check your fuses. Run some injector cleaner through your system. You know quick simple cheap things before you get to the fuel pump inside the gas tank which can be kinda expensive. The warm up then dies can be caused by, "blownout or fouled," spark plugs. I hope this gives you a general direction in which to go. A sidenote is that coil packs do not normally run an igntion code and I for one do not like them becuase they are expensive.

My 2002 jeep liberty wont keep the timing


always starts, always runs but stalls randomly, right?

is that a guess. on timing? what is the proof? a timing light?
this car has an ASD, it can drop for many reasons.
the best way to find this fast is to use that magic cheap tool called
a scan tool and OBD2 scan tool. It will tell you why ASD drops
in most cases, and if it dont,. tells you the other by process of elimination.
(still in rough draft) as is all there on jeeps.

Hard starting in cold weather, turns over but does not start easily. Starts fine in warmer weather


check if the car have the thermostat in the cooling system, because in cold weather the thermostat close the water flow in the cooling system (radiator, head of the motor) and the car gets temperature faster to warm the engine to operational temperature.

Possible solution - This happened to me and my battery was dead in my key fob and also I needed an ignition switch because a piece on it was broken which therefore wouldn't turn to start the engine.

2008 Jeep Liberty Starter Issue


cant figure out your post at all !
"When my car will not start it only growls & never roars/never turns over."
it either cranks robustly nor not
then and only the can it start, run
cranks
starts
runs
or maybe stalls
the dealer can fix it , if you demo it and it works.
its not broken then.
if it cranks correctly every time ,say so
that is a failed engine start.
if engine stalls, say so.
if rpm on the engine is real low, too low, say so.

the word turns over means nothing, Im sorry
1/2 say, it means cranking
other 1/2 means its running,
the order is
cranks, starts, runs , and keeps running or stalls.
btw if it stalls, its needs a tuneup'
get one in last decade, (sparks filters)
my guess growls is starter sounds
so if it starter works try cranking with throttle wide open
this is super secret unflood mod. it cuts fuel and clears flooding.
Good engines that fail to start are
bad spark plugs
flooding
starving for fuel.
we discount them 1 by one until. bingo

Jeep Liberty 2004 sport gas cap not sealing


You can get the silicone grease at automotive and hardware stores. Apply to rubber seal on cap about every 2 to 3 months. This will ensure a seal so that the engine light doesn't come on. Worked great on My 2008 Liberty.

My 2003 jeep liberty is showing a P0300 code. In the past we have replaced the computer and multiple vacuum hoses. I think it is prolly another vacuum problem but I dont know where to start. My...


it is multiple misfires on cylinders(random). this can be due to your vacuum leak over somehere on intake manifold. you can diagnose leaks by spraying brake pad cleaner on engine block when it is running. one location at a time. if idle speed or sound changes you will understand that there is a vacuum leak and it is sucking excess air from there. if it is only a misfire, this can be a micro crack on intake manifold.

2002 Jeep liberty headlights cut off and then back on at random times. weather makes no difference nor hot or cold. went a way for a few months and now it has started all over again. hear clicking sound...


the clicking your hearing is the relay trying to stay engaged, its heating up causing the relay to power down, which in turn you lose the lights, the heat is caused by the electrical current supplied to the replay, Not the outside temp , locate that relay and replace it, and your problem should be gone
