Fuel filter electrics snapped! Help!!

[jim_5elf]

Hi, just replaed the fuel filter and the cable snapped out from its housing in the bottom of the filter. Guess when I was screwing the filter in, it twisted and snapped the wire.

Now the car wont start - is this wire needed for starting and driving? I had thought it was only a sensor to say if it needed changing??

Obviously, I will change it anyway - but would have been nice to drive to a shop to buy a new one....

On that note, anyone know where I can buy this sensor? Halfrauds? Wilcos? I really need to use the surf this afternoon so any help would be great!

Thanks

Repair

Trim the insulation back, twist the wires together, Soldering iron, dab of solder, electrical tape the repair, job done.

Thanks Will but unfortunatley it has snapped right next to the plastic bung so its not going to be super strong if even possible. Likewise, there is no way to determine which wire re-connects to which as it is litterally just two bare wires a mm long pretruding the bung.

Does it need this sensor to start and drive?

It seems now the surf wont start and i have primed the fuel pump...

Thanks

Anyone got a second hand one? Ebay has nothing...

you don't need the sensor to start or drive!

If the engine is cranking but not starting then you most likely have air in the fuel system!

Pump the priming head whilst someone cranks the engine!!

Sweet. So do I need to actually replace it?! Maybe I could get away with a month of driving so I can get some funds together...

Thanks

You should be able to drive no problem without it! It's just a water in fuel sensor. My last 4 Runner one was broken all the time I owned it!

Happy days!

Having charged the batteries (well once anyway) over night, she still wont start this morning.

To be clear, I have been running a higher percentage of WVO than usual but with quick start spray im normally out of the shit. This time though, with diesel in the filter and it primed so its pretty firm - it still wont start. Now im having the charge the batteries again...

Is it possible wvo has congealed in the hose and I need to clear them? Im thinking to undo the fuel tank cap and then blow compressed air down the hose from fuel filter side to clear it.

Any thoughts on this idea?! Or anything else I can try to get it started??

Thanks

I replaced the filter with a different unit and have a separate primer bulb.

My filter has no electrics at all... you won't miss them!

I use WVO with 10% petrol, and it works well.

Have you checked all the bits on the IP?

Let me know if you need any more help!

Thanks Surfboy for the info, but I must say - this looks well out of my skill range! I'd struggle to even locate the Injection Pump I think...

Can I blow compressed air down both hoses from the fuel filter? I.e - into the cylinders? If that fails, then I will get more serious with the IP.

Maybe some of that redex diesel engine cleaner type stuff?!?

Thanks

You can blow back to the fuel tank but blowing the other way won't do much. You need to get into the filter bits in the pump and clean them.

If you do have a go, take the air filter assembly out. This gives you a lot more room.

I have also changed all my fuel lines to clear braided pvc so now I can see any air pockets too.

It's all doable with spanners etc. No specialist tools or skills required.

If it's never been done and you're using WVO, then cleaning the IP will be worth doing.

You should relatively easily be able to do:

1. sensor with little cylinder filter behind it
2. banjo assembly with little pinhole (don't lose the ball bearing and spring)
3. spill control valve (use 32mm spanner) and try and take the filter disc apart to clean

good luck!

I just removed the fuel in hose and fuel out hose from the fuel filter pump. When I pump the fuel filter pump by hand (with no hoses attached) no fuel comes out.

Is this correct? Or should fuel be pumped out?

Cheers

Thanks - I only just read this on page two..

This sounds like something that needs doing then. I'll see if I can beg a mate into giving me a hand over the weekend!

But any thoughts on the fuel filter pump?

[Surfboy]

You only need to remove the fuel line from the out port of the filter (or at the IP end but this is a little tight to get to)

When you pump the primer, fuel should easily be pulled from the line into the engine bay, through the filter and out the exit port on the filter.

If nothing comes out after a load of pumping, maybe the diaphragm in the pump is knackered or the fuel line is blocked.

Did you blow back down to the tank?

If the primer is buggered, buy a bulb primer and put it before the filter.

I fid try it first with the out hose removed but nothing happend. I have not blown the lines yet as need to borrow a compressor from someone...

I also just tried to bypass the fuel filter but filling a cup with diesel then insert the line dirrectly into it. Im guessing there is a lot of air in that hose now, but after several turns it still wasnt close to starting and the diesel didnt go down - so no suction there?

I will pick up a bulb primer also as it maybe useful either now or in the future anyway..
