October 6th, 2007 03:45 PM #91The throttle potentiometer does not have any effect on the injection pump's performance. It is mounted on top of the pump's throttle shaft to monitor throttle position for EGR (Exhaust gas recirculation) control and/or automatic transmission shift control.
Blocked fuel filter maybe? Or you may have an injection problem as you car is 11 years old, probably with high mileage as well.

October 6th, 2007 04:07 PM #92As I previously stated on our help desk, fuel consumption depends on so many factors. See my previous postings. Your authorized Hyundai agent can give you some figures on your question.
What is your present mileage? Does your CRDI emit a lot of black smoke?
Oil change will have no significant effect on fuel consumption. A non-original air filter could restrict air to your engine at higher rpms and result in high fuel use.
Yes, we can calibrate your CR pump. We have the equipment to do common rail pumps for Hyundais, Toyotas, etc. But before you consider calibration, I suggest that you consult your local Hyundai dealer about your problem. It is possible that you don't have any problem at all.

October 6th, 2007 10:31 PM #94I don't have your injection pump's part number, so I can't be sure about these green wires.
But if this is an ordinary Denso VE pump, these wires would most probably be from the speed sensor on your pump. You are also probably correct in assuming that these wires are connected to your tach. You will probably see a 2-wire harness near this sensor.

Sir dieseldude
Yes this wire has a harness composed of three wire in a triangular connector one of this wire controls the idle solenoid shut-off valve.
I have a follow up question what tachometer could i possibly use on these engine and also I need a guide for the wiring of this tach.
Thanks again for your reply.

October 14th, 2007 04:41 PM #96Send me the make and part number of your injection pump. Part number will be on the pump dataplate. You may also send me a digital picture of your pump. I can research the 3-wire harness for you tomorrow from our electronic database.
I may not be able to help you on your question on the tachometer as this information is limited to the vehicle manufacturer.
What is the make and model of your engine, and it's vehicle application?
Are you doing an engine change / modification?
Bye,
Dieseldude

November 5th, 2007 02:30 AM #100Hi Cocoy,
You should normally put in original ...130 nozzles as these are factory-recommended. I don't know if using ...112 nozzles has caused your problem as we haven't tried doing it this way.
I suggest that you ask the workshop which calibrated your injectors to assist you on your complaint. Workshops normally give warranty on their jobs. Did you have your injection pump calibrated too?
If they cannot help you, I would approach the problem this way:
- I would check the condition of my air filter.
- Recheck injection pump to engine timing
- Check turbocharger boost
- Check/calibrate injection pump
- Replace nozzles with original ones
Bye,
