Just replaced my dirty fuel filter last week, after replacement its noticed in hard restarting for almost 1 day used. For the second day in the morning I started my Starex CRDI 2005 model and won't start until now. What are the posssible defects since the fuel filter had been replaced with new one? I pump the fuel filter pump just to removed the air bubbles, It has been successful, there's a fuel going to fuel pump.Please help of what are the specific defects with my crdi engine. Your assistance is high appreciated. Thanks and more power

Could be something as simple as a dirty fuel filter.
Get a can of quick start at the store and have someone start it up, when it wants to die squirt a shot into the intake ... if it runs again for a bit you have a fuel delivery issue. Check the fuel pressure to see if the pump is functioning properly.

What about a worn out fuel pump & fuel pressure
when it shuts off?

A vacuum hose cut will cause a lot of symptoms, A code indicating a rich conditions indicates a lack of air, or too much fuel. A dirty air filter or a leaking injector will cause this. A faulty O2 sensor will also cause this condition.

change air filter clean fuel injectors and replace fuel filter.

Removal Procedure
Important: Always maintain cleanliness when servicing fuel system components.
Important: There is no service interval for fuel filter replacement. Only replace a restricted fuel filter.
1. Relieve fuel system pressure. Refer to Fuel Pressure Relief . 2. Raise the vehicle. Refer to Lifting and Jacking the Vehicle in General Information.


3. Disconnect the quick-connect fitting at the inlet of the fuel filter. Refer to Plastic Collar Quick Connect Fitting Service . 4. Disconnect the threaded fitting at the outlet of the fuel filter. 5. Drain any remaining fuel into an approved gasoline container. Installation Procedure
1. Remove protective caps from new filter. 2. Install a new O-ring.


3. Connect the quick-connect fitting at the inlet of the fuel filter. Refer to Plastic Collar Quick Connect Fitting Service . Notice: Refer to Fastener Notice in Cautions and Notices.
4. Connect the threaded fitting at the outlet of the fuel filter. Tighten
Use a back-up wrench in order to prevent the fuel filter from turning. Tighten the fuel filter outlet nut to 27?N·m (20?lb?ft).
5. Lower the vehicle. 6. Reconnect the negative battery cable. Refer to Battery Negative Cable Disconnection and Connection in Engine Electrical. 7. Inspect for fuel leaks. 7.1 Turn ON the ignition for 2?seconds. 7.2 Turn OFF the ignition for 10?seconds. 7.3 Turn ON the ignition. 7.4 Inspect for fuel leaks.

Based on the condition of the plugs it sounds like its running rich. I almost wonder if someone sold you the wrong pumps and you have too much pressure or something.

Could also very well be whacked injectors. I am thinking it may even be a timing issue...

Try replacing the fuel filter and check the fuel pressure at the shredder valve. Low fuel pressure from a week fuel pump or dirty fuel filter will cause hard starts, a bad ground will also do the same thing so check the ground wire for the fuel pump which is separate from the main wire harness to the fuel pump sending unit.

Good luck and thank you for using FIxya.

Your fuel filter may have gotten to the end of it's life and needs to be replaced. Start with the simple and replace the fuel filter, a dirty fuel filter will not set the check engine light to come on, at worst it's a weak fuel pump and that may need to be replace. Good luck and thank you for using Fixya.

Have you replaced the fuel filter, spark plugs and wires? A plugged fuel filter will cause a fuel pump to go bad because it works harder to pump. It also may cause less pressure. Plugs, wires cap and rotor will cause lack of power and fail you on a load if they haven't been replaced for a while.

tell your mechanic to replace the fuel filter. This part is usually less than $10. It should be replaced aout every 50K miles.
