Could have a faulty low pressure switch. The low pressure switch is located on the air conditioning line in the right rear of the engine compartment near the firewall. The low-pressure switch in your air conditioning system is used to interrupt power to the compressor when the low side pressure drops below 25 psi. This prevents freeze-up of the system and possible damage to the compressor. When the switch is faulty, the symptoms of freeze-up, or no compressor function, will be present. Replacement is straightforward, but requires the removal of refrigerant from the system.

you should have your fuel pump pressure tested. your pump may not be holding pressure and loses power while driving also when its parked the fuel may be leaking back into the tank. whoever told you your cats were bad got you for some money.

you could have a bad parasitic draw on your battery this video might help you. How To Perform Parasitic Draw Test EricTheCarGuy

was the ecm flashed to the vehicle and also timing belt might be installed incorrectly ----vehicle off time both of those will cause a non start but also check connections and power to ecm as well as to other sensors that were disconnected during repairs

If the relay clicks, you're not getting power to the field coil on the compressor and I doubt it the control circuity is the problem. We've replaced compressors on Sedonas and Sorentos for this same problem. Uunplug the compressor field coil and hook a test light between the field coil power wire and ground and have the a/c button on. If there's power there, then you have a bad field coil. You can buy the field coil separate from the compressor but you'll want to buy 2 new snap rings. one snap ring holds the pulley on and one snap ring holds the field coil on. I don't recommend messing with taking any part of the compressor apart unless you're experienced with a/c systems and have the proper equipment to recover the system. the pressure in and a/c system isn't anything to play with.

One other thing, have you checked the compressor fuse (thermistor)? I can think of checking before giving up is the thermistor. I know the connection is behind the glove box somewhere but I'm not sure where.

Hope this helps.

it should be easy

If it's miss firing then I would check plug and ignition coil first usually ignition coil is the problem.

blown head gasket

I have change almost all engine set and cost me around 276000.00 ngultrum. Now no problem

Hi Rodney. Can you tell me what makes you think the oil pump might be faulty. Is your motor noisy at idle ? How often is the car serviced ? Do you know what grade of oil has been used ? Do you have a "check engine" light on the dash ? If you can fill me in with a few more details I'll be more than happy to help you :) Cheers Peter Smith

Who did the work? take it back. If it's DIY double check your work. Knoking as in metalic engine , or knocking as in gas preignition. If gas preignition, timing belt is off a few notches. If it's similar to this google: 2003 kia sorento interference engine You may have valve timing off so much that your pistons are running into the valves. Bad news!

Please check the following: - Manifold Absolute Pressure sensor (MAP) or MAF. - Fuel injector's connectors and wiring. - Ignition coil's connectors and wiring. - Vacuum hoses and pipes. - PCV Valve. - Spark plugs for any cracks on the insulators. - Spark plugs gaps. - Fuel pump pressure. - Engine Coolant Temperature sensor. - Cam position sensor. - Crankshaft position sensor. - Valve timing.

These foreign cars usually light up like this when the alternator is bad. Check battery voltage with vehicle off. Start vehicle and check again. It has to be at least 1-1.5 Volts higher than when off. If not, charging error and usually the alternator. Good luck, Vinnie

If the coolant temp is hot the fan will keep running till cools , if it stays on after this the censor may be at fault.

You answered your question. The light is on because the computer detected a problem, which is noted by the trouble code. You would need the diagnostic chart for that code to find the actual problem.

Yes the Green squares are locks. Press them inwards and remove the fuel lines. Also watch vedio at the following you tube link: https://www.youtube.com/watch?v=fYR5me-Nqeo

check your connections, also the cable adjustment...it may be working but the adjustment is off If you need further help, I’m available over the phone at https://www.6ya.com/expert/david_4c166ba81493f541
