Saff cossie 4x4 wont start
 

Hi people.

Today ive been on fitting new fuel lines to my cossie.

I went to start the car and it just cranks over. The fuel pump primes but when cranking i dont think ita doing much.

Ive got a very faint spark. Ive took the plugs out and they are bone dry. After ive cranked it i can hear loads of what i think is sensors clicking under the engine bay.

Ive give up for today but i defo think its an electrical fault.

Im gonna try the ecu and fuel pump relays later.

Any ideas people.

Phase sensor would be my first check.

How old is the fuel? Mine hadn't been started for about 6 months and wouldn't start, I put a fresh battery and fresh fuel and starts bang on now.

Also i took the fuel pressure regulator off the fuel rail and there is no fuel coming out of it. So im thinking fuel pump relay.

The fuel is fresh and im sure the phase sensor is ok too.

The car ran fine over a week ago cause i took it for its mot.

Phase sensor is fine, it sounds like it may be a simple air lock perhaps?

Mixed up fuel lines?
Fuel comes out of the rail,not the regulator.
Take the line off the bottom of the reg,if fuel flows the lines are mixed up.
Not forgetting you're window seal,I'm breaking a 4x4 this week so I'll have even more spare,just not been near my mums to get the seals from there.

So the fuel from the tank doesnt go to the fuel regulator??
Yeh no worries about the window seal matey.

I just think its something electrical.

Correct,it goes from the pump to the rail,fills the rail then the reg must release unwanted fuel from the rail back to the tank,I'm guessing it will be a 1 way affair so if it's hooked up back to front it won't start.
Makes sense too as that's all you have done is swap the fuel lines out.

That's it Glenn the regulator is the return line ;)

Never i thought the fuel went to the regulator on the end of the rail first.

Ive had a look at my workshop repair manual and i think i have the pipes the wrong way round. I bloody hope so lol.

I will get back onto the car today and swap the pipes round.

Shhhhhheeeeeeesssss alive.

Im so thick. I just thought the regulator regulated how much fuel was going into the rail.

Thanks people. I just hate it when my cossie isnt right. I just sit at home thinking what it could be till i sort it.

Glad she's sorted mate, the regulator controls the flow out of the rail to keep the rail under a set pressure like 3.5bar for instance just like the pressure relieve valve on some common rail diseasals.

What fuel lines did you use in the end up?

I just feel so thick lol.

I used copper lines and ive used similar joins like the standard ford ones.

Heres a pic of the clips/joins ive used on the pipes. If there good enough to be on trucks hopefully they will be ok on my car.

There very similar to the clip/join on the standard pipe.

Did it start fine before you did what you did? If so it has to be something you have done.

Well it started fine a week ago lol. With the clicking noises under the bonnet and thw fuel pump not sounding right i thought it might of been a sticky ecu relay.

Nice one Lee.

Glenn, it had to be related to the lines somehow, as there was no other explanation for it.

I know i just thought it was electrical.

Thanks for all your help people.

I was going to say you had the fuel lines on the wrong way round but you have sorted it.

Just been out in the saff this afternoon just to check these joins. All ok and no leaks. I got my mate to follow me incase i broke down lol.

Cossies are a bloody old bone shaker but mine still makes me smile.
