Default 2002 Sedona fuel pump issue

2002 sedona 2.9 deisel


Initial symptoms
It lost all power (without stalling tho) while driving, which could be rectified by removing my foot off the accelorater then putting it back on. After a while, it happened while driving on the motorway but wouldnt be rectify....it just glided to a halt.

Current situation
it wont start at all, i have had a few mechanics take a look and they seem convinced that its the fuel pump (mechanical) after testing a few things. It will try and fire if 'easy start' is sprayed in the air intake while turning over, but other than that there is nothing.

All local mechanics are running a mile and wont touch it, so it has been left to me.

HELP!!
I have found a breaker with good condition second hand pumps so want to try and fit it myself.

EDIT: I have managed to find instructions on how to remove the pump, I have also found out it is a CRDI pump....well it looks like this one.

Is it possible to refurb these pumps? or test the sensors as it is described in the listing?

any help/advice would be greatly appreciated!!!!

Thanx in advance

first thing to check would be the fuel filter, has it been changed recently?
take it off and see if there are metalic particles in the bottom as this will almost certainly show your pump is fubarred
there are several outfits who can refurb injector pumps (will try and find links)
first test is a pressure gauge on the rail to test pressure
the next test is where a set of graduated bottles are connected to the injectors to measure leakage

Thanx for replying! its nice to finally have some help.

The mechanic who last looked at it, took off one of the pipes from the rail to show me the fuel pressure, and it just trickled out - he said it should be under massive pressure, which it definately wasnt.....although pressure did build up after about 30 seconds of turning the engine over. do u still think i need to test the actual pressure with a guage?

I just epmtied some fuel from the filter, and i cant see any particles in it. Also, i dont know if it is a good enough test, but the primer pump on the side of the filter pushed fuel thru with ease so i would say the filter is not blocked.

injector systems operate at very high pressures but rather low flow so just opening the rail and getting only a dribble out,only means a low flow so i would suggest getting to a specialist to check it properly
as for the filter if you are not sure when it was last changed i would advise replacement but first take the old one off and remove the water drain from the bottom and drain into a clean bowl

WARNING fiddling with high pressure lines can be very dangerous as you could inject diesel through your skin

Ok i will drain the filter and try that.

do you think I should put the engine mount back on before turning it over? I have the engine supported on a block of wood under the sump?

As long as the engine is supported well it's ok to turnover/run the engine for short periods, I've done it lots of times on my Sedona and on other cars. Just make sure its not in gear and be sensible and you'll be ok.

OK thanks, i thought it would be ok, i have it well supported and it wont take long to find out if it has worked.

Just a thought.....with second hand pumps being £200, and the known issues with them; Would it be worth trying to modify the car to run on an electric pump if i can find one that delivers the correct flow and pressure? (assuming i can confirm if it is the pump)

also, there are two wire connections on the pump, and one on the filter... is there a way i can check these sensors or what ever they are, are doing there job?

UPDATE:

Following 93fxdl's advice, i removed the filter and drained it. I found there to be lots of bits and crud in the deisel so i thought i'd check just how blocked it actually was.

I read online that a crude check of a filter is to blow thru it (using clean pipe on the connector so not to poison myself). when i done this i could barely get any air thru it at all; so i have now come to the conclusion that the filter is majorly blocked.

The particals didnt look like fragments of metal so there is a slight hope the pump may be ok

A new filter has been ordered and i will edit this post to show the results.

UPDATE II

The new filter made no difference

I took the fuel container that I drained out the old filter into and placed a magnet underneith....low and behold the particals where metal.....the pump is fubar!

I know the offical way of doing the job would be to replace the pump, rail, injectors, pipes, filter and clean out the tank...but is this my only option???? coz it is way too expencive!

My thoughts are;

1. Find a running sedona being broken down and buy all the parts i need (assuming injectors are interchangeable)

2. Have the pump re-built and injectors checked/repaired and hope the rail,pipes and tank are ok after a clean out

3. just stick on a second hand pump and prey.

Anyones input on this would be great! Thanx!

Do the injectors need to be programed in when being replaced?

Default debris in fuel filter

Hi,
If there is any debris in the fuel filter wouldn't it be from the fuel tank? Not sure about yours, but my Sedona and every other diesel engine I have ever worked on has its filter located between the fuel tank and the injection pump. Why would you want to filter fuel that has already gone through the pump???
My 2001 stalled recently and I am not getting any fuel to the filter unless i manually prime it. Therefore there is no fuel for the injection pump to deliver. There are 3 wires going to the top of the fuel tank, one has low voltage for the fuel guage and the other 2 have nothing. Any ideas? Neither fuse boxes have anything labeled "fuel" or "pump"
Scott
