Right guys this is the story.

A van at work come in with a knocking noise.It sounded like diesel knock.I got the fault codes and im sure they were cam timing?? and fuel solenoid??(eve got them written down at work).So i asked one of the lads at worked who worked on fords for years,he said it was the sensor/solenoid inbetween the fuel pipes on the pump.So i took the inlet manifold and the fuel pipes to get at this sensor.The fuel solenoid valve came and it looked nothing like the one inbetween the pipes.I noticed there was a sensor at the back of the pump.I took it out and it was the same as the new one.I repaced the sensor and joined the wires together.

I rebuilt the engine back up and it wont start now.Ive put an electrical pump between the fuel filter and the fuel pipe to suck the fuel through.Im sure it must have an air lock.If you squirt some easy start down the inlet pipe the engine will run.Ive been doing this and was hoping it would help suck the fuel through.

Ive also cracked the injector pipes off to get the air out.Should the fuel squirt out??

I was thinking about taking the new sensor out and refit the old one.

Any info would help.Thanks.

 

The van is a 55plate too.

 

Has it got a lifter pump

 

Is there fuel pressure at the injectors

 

Tow start.

 

^^^^make sure the timing spot on first.. But tow start would get it going as if the high pressure pump needs that extra boost that the starter can't do it will fire up

 

Should it have a lot of pressure.Its sort of spitting out of the injector pipes.There doesnt seem to be much pressure there.

 

It drove in ok but was just a bit low on power and when i give it a squirt of easy start it ran fine for a while.

 

I was thinking about this.

 

If its got common rail then yeh it should have loads of pressure otherwise it should still have pressure but not as much, I would look at the pump as the diesel knock you may be hearing is low pressure, if there isn't the required amount of pressure to crack the injectors it will knock, has it got 2 pump one low and one high or does it have the lifter pump built into the high pressure pump

 

It defo hasnt got a common rail.The fuel pipes from the injectors go straight to the pump.

 

Ok then it not going to have 150-200 bar ish like the common rails, if you crack each pipe so diesel pisses out, will it try to start

 

Has it bin on a code reader aswell, if yes plug it in again and go into live data and match the desired injection start (degrees) to the actual injection start to see if the pumps too advanced or retarded

 

will no doubt be the computer on top of the pump they tend to cause diesel knock and lack of power then fail pretty soon after causing a non start, they can be repaired and are easy to take off

 

Yeh these are common if its bin running rough it will keep trying to compensate to keep it running

 

When ive cracked the pipes off and cranked it the engine just turns over and doesnt attempt to start at all.

 

I put the ids(the proper ford diagnostic tester) on it and it was still the same codes.I will have to post the fault codes tomorrow when i get to work.

Im pissed off at the lad who told me it was the sensor on the pump inbetween the fuel pipes cause i wouldnt have this fault if he told me where the correct sensor was lol.

 

Are the injectors pressure controlled or electrically controlled

 

These things happen though 90% of the time with transits the faults are pump related, but it could just be a crank/cam sensor

 

Or better yet out of fuel(stuck fuel sender)

 

So what have you replaced Glenn? The solenoid at the bottom of the pump, not the one inbetween the injector pipes? If so, did you make sure that the old rubber o ring that sits at the end of the solenoid came out before you fitted the new one?

 

The codes associated with that solenoid are P0149 and P1564 btw

 

I fitted the one at the back of the pump.Now i think about it.The old sensor came out without the rubber o ring so i thought i was still in the pump so i took the new o ring off and put the sensor in.

I was thinking about taking the sensor back out and checking the seal.

 

Yeh P0149 rings a bell.

 

and make sure if you did change that solenoid glenn that it is as tight as youy can get it .i changed mine a few months ago and it wouldnt start with a tow or anything .gave that big retainging nut a tap with a long screwdriver and hammer and away it went with a bare turn of the key .

 

I think the one your on about is the one between the fuel pipes.

 

When i took the 2 allen keys out of the sensor they were loose.One of the allen bolts was nearlt right out of the threads.

 

It is quite common for the o ring to stay in there Glenn, I'd take it off just to rule it out first personally

 

Yeh im sure the old o ring was left inside thats why i took the new one off the sensor.I will remove the sensor just to check the o rinf to make sure its sat in properly.

 

Right the fault codes are

P1049 fuel timing error

P1564 Requesting reduced fueling mode.

 

It will need that solenoid at the bottom of the pump then mate, there was a tsb about it years ago, it's the pump timing solenoid. If that o ring isn't seated right it could have air ingress which will prevent it from starting.

 

Right i will check the seal again when i get some of these other vans out.

Thanks to you all for your help.

 

UPDATED.

Right ive removed the sensor and the o ring was still inside.Ive check to see if the electrical crips have made a good connection cause i cut the wires one at a time and joined them with the crips provided.

Ive got a 12volt feed at both the sensors wires.

Im gonna build it back up again and hope for the best.

 

Built it back up and it still wont start.Bastard van lol.

 

SHE,s ALIVE......
Squirted some brake cleaner down the inlet pipe and she fired up lol.




Thanks for all your help.

 

Result lol

 

I will try it again this morning.

I hope it starts lol.

 

Best of luck

 

Diesels are hateful when they go wrong aren't they!!!
Hope it worked Glenn!!!

 

Is the tddi or tdci the better of the 2?
