What happens if you burn out the injector in a Jeep Liberty?
Just like you can burn out anything electrical, you can burn out one of the injector drivers in the PCM while the rest of the PCM remains and functions fine. The engine would run like crap, because one cylinder would be getting no fuel at all.
Why does my Jeep have a P0 300 code?
Recently the jeep has thrown a P0 300 code and I have changed spark plugs and coil packs and still have the issue. I am being told It could be exhaust valve sticking on the head.
Why did my left side cylinder on my Jeep misfire?
I just had my left side cylinder head replaced at dealership after a year and a half of them telling me the symptoms (rough run with loss of power intermittently, usually on hot days) was caused by dirt in the cylinder . !! So they replaced it under recall at 138000 and 9 years believe it or not.

Where are the coils on a Jeep Liberty?
This motor has 3 coils and they snap directly on top of the spark plugs 1,3,5 on the right side. The left side does not have their own coils. Three spark plug wires run from the left and snap on to the side of one of the three coils that are on the right side.
How to write firing order on a Jeep Liberty?
– THE BACK COIL, WRITE A (5) ON TOP OF IT & WRITE A (2) ON THE SIDE OF IT AND A (2) ON THE END OF THAT PLUG WIRE. ON THE LEFT SIDE DO THIS: – AT THE FRONT SPARK PLUG, WRITE A (2) ON THE MOTOR NEXT TO IT AND A (2) ON THE END OF THAT PLUG WIRE.

Is the wire from injector to PCM good?
Wire from injector to PCM is good . Could anything besides a bad PCM cause the PCM to not send the ground signal to fire # 4 injector only ? Welcome to Allpar.
How many relays are in a Jeep Liberty?
Engine Compartment Fuse Box Diagram № A Protected Component 1 40 Blower Motor Relay 2 30 Radiator Fan (High Speed) Relay, Radiato 2 40 Radiator Fan (High Speed) Relay, Radiato 3 50 Park Lamp Relay, Daytime Running Lamp, H
Why is my PCM not working on my Jeep Wrangler?
You also lose communication with the OBDII data port & a scanner will not “communicate” & not read. The cause may be a failed PCM but also possible that one of the sensors or its wiring is shorted to ground.
When to set p0202 injector circuit open cylinder 2?
The P0202 is set if the Engine Control Module (ECM) is detects a low or high voltage drop or resistance at the injector 2. Engine Control Module ( ECM) checks the injectors circuit resistance and monitors the voltage drop during normal operation.
How can I find the correct resistance for my fuel injectors?
Tip: You can find the correct resistance for your injectors by searching online or in your vehicle’s repair guide. Step 1: Turn the car on. Turn the key to the second (ON) position for this test. You want battery power flowing, but don’t want the engine running. Step 2: Set up DVOM to measure DC voltage.
When do I get the p0202 code on my Jeep?
The ECM will trigger the P0202 code when the resistance or voltage drop at the injector 2 is out of specifications. Need more information on how to fix the P0202 JEEP code?
How to diagnose a p0204 jeep fuel injector?
Visually inspect the related wiring harness and connectors. Check for damaged components and look for broken, bent, pushed out, or corroded connector’s pins. How much do you know about cars? The cost of diagnosing the P0204 JEEP code is 1.0 hour of labor.
Wire from injector to PCM is good . Could anything besides a bad PCM cause the PCM to not send the ground signal to fire # 4 injector only ? Welcome to Allpar.

Why is my PCM # 4 injector not working?
A P0204 is likely one of 3 things, either the #4 injector itself, the circuit to (+) or from (-) the injector is shorted or open, or the internal PCM #4 injector driver has failed (serviced by replacing the PCM). Resistances can be OK, but misleading.
What causes no power to fuel injector pulse?
Ans: The engine control unit is the electronic brain that used to control the fuel injector pulse by gathering data from various sensors along the fuel line Question: What causes no power to fuel injectors?
How does the engine control unit control the injector pulse?

A P0204 is likely one of 3 things, either the #4 injector itself, the circuit to (+) or from (-) the injector is shorted or open, or the internal PCM #4 injector driver has failed (serviced by replacing the PCM). Resistances can be OK, but misleading.
What does it mean when your fuel injector is leaking?
If the valve seat in the injector is leaking or the pressure regulating valve leaks then it will not build enough rail pressure to start the engine. The fuel system contains high pressure fuel up to 23,500 PSI. Do Not use your fingers to find leaks!
What causes the solenoid on a Jeep Liberty to become sticky?
Fuel contamination can cause the Fuel Quantity Solenoid to become sticky and erratic. Buy Jeep Liberty 2.8 Fuel Pressure Regulator If the engine hangs at higher rpm or is slow to decelerate, injector wear is what normally causes this problem due to excessive return. Injectors will need to be replaced.
Why does my Jeep CRD fuel pressure solenoid not work?
Buy Jeep CRD Fuel Pressure Solenoid If other work has just been performed be sure that the #4 injector connector and the fuel pressure solenoid connectors are not swapped. This will cause the fuel pressure solenoid to dump pressure and the engine will not start.
How can I tell if my fuel injection valve is bad?
Check for return with the engine running, and if possible, use a scan tool to run the high pressure set point test. There should be minimal to no return from the fuel pressure solenoid. If there is more than 15-20cc in 30 seconds, the valve is likely bad. A good solenoid will typically not leak any fuel while cranking or at idle. It takes about 2]
