Car broke down - advice ?

[BoozerDawg]

Hi all

I took a trip up to Newcastle on Friday in my 2007 Focus 1.6 TDCi (82000 mileage), made it there no problem. On return, I was about 20 minutes away from home (its a 4 hour 40 drive), I felt the engine grumble for a second, and suddenly the car no longer accelerated and was rolling to a stop (all electrics were still on). Pulled it over to the side of the dual carriageway, tried to start it again, nothing, just keeps trying to turn over. Had it towed back home. The guy had a quick look under the engine for me, not sure what he did, but he had me try and start it while he looked at something. He said he couldn't see any fuel coming out, so he suspected the fuel pump had gone.

I checked the codes today, this is what was logged -

End of report.

I also cant hear a fuel pump priming when putting the keys to position II, and from what I can see, a fuel pump replacement on this car is a costly job (I'm not even sure where it is on the car, not up to speed with diesels at all, some say in the fuel tank but not accessible from under the rear seats, others say in the engine bay).

Only thing I can think of is getting a mobile mechanic to come over and take a look at it, but thought id ask here first to see if there is anything else I should try. Kind of gutted, only owned it for 2 months

And yes it did have fuel in it

If you can't hear the fuel pump prime, I'd check the fuses. My brother in laws mk1 focus did this and I diagnosed it and replaced the fuse, job done.

Fuel pump.

P1180 Fuel Delivery System - Low- Permanent
P0087 Fuel rail System Pressure -Too Low- Permanent

I had a 1.6 petrol and the fuse went twice. N the petrol it's in the fuel tank under the seat but it cant be changed that way. The tank needs to be dropped which isnt really a big job. They can cut a hole under your seat bit that's not recommend as it will weakens the structure

 

[BoozerDawg]

Had a look earlier to see if it could be a fuse, looked at what was supposed to be the fuel pump fuse (according the manual, number 111), and there wasn't even one in there. Some forum posts suggest TDCi's don't need them, others said the pump was ran off the timing belt (??).

The fuse I changed in my brother in laws car was a 1.8 petrol, it was under the bonnet, near side. It was a red 15amp job. His was an 03.

There maybe 2 pumps

A Low pressure pump inside fuel tank and a High Pressure Pump ran by the cam belt..


(But I cannot confirm this as I never worked on a diesel focus)

It can - you just need to lift the rear seats, pull the rubber cable bung out and enlarge the hole with tin snips then you can unscrew the fuel pump retaining ring and remove the pump. I did it exactly that way when changing the fuel pump on my wifes Mondeo.

It's the same on the OP's Focus.

Diesels often have two pumps, a primer/llift pump that gets fuel from the tank to the engine bay with an initial pressure of ~25psi, you then have the pressure pump on the engine that outputs the 5000psi and up that the injectors need. A lot of 'modern' diesels don't have the primer pump which make them a grand PITA to get going again after a fuel filter change.

The high pressure pump is ran from the cambelt and that will need checking, not all of the tdci's have primer pumps and if memory serves the 1.6's usually don't.

Lol you highlighted part of what I wrote, but didn't read the rest were you are agreeing with me.

But if you want to do it the cheap way and risk your car folding up when some rear ends you that your problem.

Taking tin snips to the floor to remove the pump, classic.

 

[BoozerDawg]

Thanks everyone, think I will definitely need to get a mobile mechanic out to take a look. Had my brother listen at the fuel filler if he could hear anything when I turned the key, absolutely nothing. Just hope this wont be too costly :|

Its not structural, its fine.

We're talking about a Focus, it's an entirely appropriate procedure

I was advised by 2 "professionals" that it will weaken the car. What's the point in risking it for the sake of a few quid more anyway? Its can't be welded back up either. Or it could if you want to risk getting blown up

It's lazy.

 

[BoozerDawg]

Is it common if the pump fails it has damaged other components (trying to reduce my fear of a big bill ) ?

Its an idea to change the fuel filter at the same time in case the pump has broken up and sent metal upstream but other than that, no, they generally fail in isolation.

It's lazy.

I will always choose a lazy person to do a difficult job because a lazy person will find an efficient way to do it.

You all seem a bit target fixated on a component that I'm pretty sure your car doesn't have...
