Hyundai santa fe 2003 diesel difficult starting ok when started.glow plugs all ok. high pressure diesel fault?low pressure pump tested ok.help

if you are talking power steering system, the whine is a vibration in a problem control valve and could be in the steering valves on the rack

what is the probable cause of error code U0019 hyundai starex 2002

there have three factors may be cause the problem,
1.The filter is a source for low fuel pressure, because it is stoped up or is cloged.
2. The fuel pressure regulator is another.
3. The pump itself.

Initially I would agree fuel pressure had dropped off after shut down. This fuel filter is a sock screen attached to the fuel inlet tube of the fuel pump and is located inside the fuel tank with the fuel pump. This screen is rarely the cause. You'll need a fuel pump pressure gauge to verify the low fuel pressure at start up. Caution, sometimes this low pressure isn't a faulty pump, sometimes it's a poor wiring connection to the pump motor. An analog amp meter can verify if there is fluctuation/ing current flow to the fuel pump. A fluctuating current flow could mean poor connections, or could mean the pump has/is gone/going bad.

Petrol or Diesel? If petrol it's probably engine coolant temperature sender and if diesel it could be a defective glow plug or cold start device/pump timing.How you had glow plug draw test done?Is there any smoke and if so what colour?

I think you have a failing fuel pump, the fuel pressure check valve (part of the pump) is defective is my guess

hi there you will have to relpace the pump this is a comon fault.

thanks ****

If I am Correct, This is not a Diesel Burning Car Right???? If not you will not have Glow Plugs. Glow Plugs were only Installed on Diesel Engines to Preheat the Motor Before Start.

possibly 1 of the fuel injectors is malfunctioning causing a fuel lock,try getting them tested

I have just had the same problem but solved it.
Firstly, I went to Halfords and purchased a spray tin of Bradex Easy Start.
Then loosen off the air filter cover and give a quick spray inside.
Turn the engine over and bingo, it should start.

What you need to look for is whether the smoke from the exhaust is white. If it is, there is too much unburnt fuek in the engine and the problem lies with the glow plus.
