I'll try turning key to II for 2 seconds on and off a few times and let you know if that has an effect. Bad line makes sense to me. Fuel pump does not because the problem has been happening for at least 3 years.....the pump would be dead buy now.

Thanks guys.

 

Stranger things have happened. Sounds like you have a fuel pressure issue. If you have spark and air, next on your list is fuel pressure.

 

So far cycling the key between II and I prior to starting has been working. There was one time that it took 2 cranks, but it fired right away.

I'll trace the fuel lines from the tank up and see if anything is out of place. Can anyone help me out by telling me where the fuel filter is? I checked in RAVE and the only fuel filter I found was for diesel engines. I've noticed LR likes to use weird names for some parts, so maybe I'm just searching for the wrong stuff.

 

The fuel filter on a D2 is unfortunately built into the fuel pump itself and is unserviceable unless you want to replace the whole pump. I am 99% sure on this, some one please correct me if I'm wrong though.

 

Another thing you can do to verify fuel pressure issues: get the car running and turn it off. Then after a couple seconds turn it back on. Even with a bad pump there should be enough residual pressure to start right up immediately. Not sure if anyone has mentioned that yet.

 

Same exact thing with mine. I can hear fuel pump when in number II position. I will be renting a FPR tester from autozone tomorrow.

 

I have a this same issue, was told to try a new pump and installed it. This did not help, same issue, fuel bleeding down to 0 and pump not priming. Starts fine immmediately after shut off but after pressure bleeds take 5-7 seconds of cranking to start. Please HELP! What did you end up finding out on this?

 

I have not checked the LR DII myself, but on some fuel systems, there is a check valve that will not allow the fuel to return to the tank. Could there be a Bad check valve that is allowing the pressure to fall back to tank?

 

There is no check valve per say other than the fuel pump. The fuel pump regulates fuel pressure internally. Once fuel leaves the pump it goes down a single fuel line to the back of the fuel rail. There is a schrader valve on the back of the fuel rail in the center to check fuel pressure with a gauge. The most common reason for your issue is a fuel injector o-ring isn't sealing correctly or one of your injectors is bad. Both allowing the pressure in the rail to bleed off. Basically the fuel pump, injector o-rings, injector, or a old cracked fuel line/bad quick connect seal where it plugs into the fuel rail fitting, or bad crank sensor are the things to check. If this only happens when the engine is warm. Crank sensor.

 

Hi everyone, first time poster here! Thanks for all the great advice so far over this whole forum, has helped me multiple times work on my '04 Disco II. I'm having a similar problem with the engine taking 2-3 cranks before it starts and thought maybe I could bring this thread back to life!

These are the symptoms and things that I have tried so far.

First off, this only started once I replaced the fuel pump. I had the truck for a whole year with zero issues starting ever. Fuel pump died, towed the truck home, ordered new fuel pump, installed it and everything worked great! I went off roading one afternoon and the first scenery stop is shut off the engine and the next time I started it and every time after that it would take 2-3 cranks to start.
Exceptions - Cold starting the engine works first cranks but about 3-4 seconds into cranking. Starting the engine within 2-3 minutes of shutting it off it starts immediately like a normal engine would.

If I leave the vehicle sit for 10 mins or 30 mins it goes back to taking 2-3 times to start. No matter how long I let it turn over on the first crank it will never start. If I let it go long then it usually will start on the second crank. If I do 2 quick turn over like 2 seconds each, it will always start on the 3rd one.

Thing I have tried - I took that new fuel pump back and got them to replace it under warranty - The new fuel pump does the same thing ( so that could rule out a bad fuel pump or I'm unlucky enough to have two crappy ones)
Thing I have tried - priming the engine first 2 or 3 times with the key all the way on in the ignition. This works when the Vehicle is warm sometimes but doesn't always.

There is no fuel leak anywhere that I can find, and to be fair I'm not totally sure where to look, I have check and cleaned the Schrader valve on the fuel rails, there is pressure but doesn't appear to be leaking at all.

I do feel as though this is hard on the starter and is going to ware it out quicker than it needs too and it's just a pain in the butt. Wondering if anyone has any insight or experience with this type of issue? Thanks again for all the help everyone, it's really appreciated and I'm hoping one day I will be able to help some one else with their vehicle troubleshooting and repairs!
