Engine (fuel?) problem from USSR.

Hello.....or Zdravtvuyte

Can somebody help me with my problem. I use my compass (2008 53 000 kilometeяs) in UKЯАINE. We have low quality gas here. Maybe that is the reason of my problem. The car starts to twitch when I am pushing accelerator to fool throttle (sometimes engine signal lamp blinking over 4200 rpm). I have regularly change oil and oil (air) filters. Maybe problem in sparking plugs or in fuel filter... How to change fuel filter in compass? Please help me or I'm going to install vodka fuel system...


Thanks for help

The fuel filter is part of the fuel pump module and mounts inside the tank. I'll post some pictures tomorrow for you. Do you have FWD or 4X4 and what octane is your fuel there or is it just dirty fuel?

The MK's only require 87 octane so that shouldn't be the problem. I do suspect contamination, primarily water in the fuel. I would first try some kind of gas "drier" or "de-icer" to try and get the water to mix with the gas. If you have already tried that then follow these next steps.

FUEL CONTAMINATION

If an engine's fuel supply has been contaminated, the following procedure must be followed:

1. Remove all fuel from fuel tank. Use an appropriate fuel container. Dispose of contaminated fuel through the proper procedure of disposal. Clean fuel tank. This will require removal of the fuel tank to make sure all contaminated fuel is removed. (Refer to 14 - FUEL SYSTEM/FUEL DELIVERY/FUEL TANK - REMOVAL).
2. Install fuel tank to vehicle, (Refer to 14 - FUEL SYSTEM/FUEL DELIVERY/FUEL TANK - INSTALLATION).
(I can post instruction for removal and install if necessary)
3. Fill fuel tank with fuel.
4. Check for DTC's and clear DTC's.
5. Start vehicle and run engine for 15 minutes and turn off vehicle.
6. Check for DTC's and clear DTC's.
7. Road test vehicle.
8. Check for DTC's.
NOTE: Dispose of Petroleum based products in a manner consistent with State, Federal, and Provincial Regulations.

The engine should then be evaluated to determine if the contaminated fuel has caused any damage to the fuel system and or engine. Indicators that the fuel system and or engine has been damaged are the following:
  • Unstable fuel rail pressure. This can manifest itself as instability at idle speeds, excessive undershoot/overshoot at engine start, or excessive undershoot/overshoot when the engine operating conditions change. A typical engine response to a large rail pressure undershoot would be a decrease in engine speed or engine stall.
  • Excessive noise from the engine. This could indicate poor rail pressure control or the inability of the injection system to inject the proper amount of fuel.
  • Excessive smoke (black or white). This could indicate inability of the fuel system to inject the proper amount of fuel.
NOTE: If any of these conditions are exhibited after cleaning the fuel system, proceed to the appropriate fuel system information. Repair fuel system and or engine as necessary. (We can cover these areas later, if necessary.)

All instructions start with releasing the pressure when working on the fuel tank.

FUEL SYSTEM PRESSURE RELEASE PROCEDURE

1. Remove lower rear seat cushion. Fig A (NOTE: requires T-55 Torx bit)

2. Remove the fuel pump module cover. Fig B

3. Disconnect the electrical connector for fuel pump module. Fig C
4. Start and run engine until it stalls.
5. Attempt restarting engine until it will no longer run.
6. Turn ignition key to OFF position.
7. Disconnect negative battery cable.
8. One or more Diagnostic Trouble Codes (DTC's) may have been stored in PCM memory. The scan tool must be used to erase a DTC.

Removing Fuel Pump Module ALL WHEEL DRIVE

WARNING: Release fuel system pressure before servicing fuel system components. Service vehicles in well ventilated areas and avoid ignition sources. Never smoke while servicing the vehicle. This may result in personal injury or death.

Fig A shows the AWD Fuel Tank with left and right modules. Front Wheel Drive will only have one module, I believe it’s the left side.

1. Perform Fuel System Pressure Release procedure.
2. Remove the air cleaner lid, disconnect the inlet air temperature sensor and makeup air hose.
3. Remove the negative battery cable.

Fig B
4. Remove the rear seat cushion.

Fig C
5. Rear seat cushion loose.

Fig D
6. Remove plastic cover.

Fig E
7. Clean top of tank to remove loose dirt and debris.
8. Use special tool Spanner Wrench #9340 to remove left side module lock ring.

You are aware that octane ratings are calculated differently in the U.S. and Europe? American 87 octane rating would be roughly equal to European 95 octane rating, AFAIK.

It's a Jeep Patriot thing. You wouldn't understand.

I did know that they were different but I wasn't sure how, thanks for the info. Tony, it sounds like you have the manual that goes with the export model, is the "95 octane" stated in there?

I did find this rather handy chart Googling. It looks like the 92 EURO rating is about the equivilant of the 87 US rating.
