replaced fuel filter CAN'T START

18 posts in this topic

Hi, I've just gave my car a full service and now I can't get the engine to start.

Pretty sure the problems with the fuel filter (bleeding).

I've serviced many cars before and had no problem, I just replaced the fuel filter and turned the engine a few times and they all started no prob.

No fuel was coming through so I removed the outlet hose of the filter and sucked the diesel through but still no joy in starting.

The car is a MK2 Focus Zetec 1.8TDCI.

Any advice would be excellent.

Sounds like air lock. Has your car got a squeeze pump in the fuel line under the bonnet? not all cars have these fitted as standard but if its there, give it a few pumps and it will suck through.

Some manufacturers get you to buy it as a service tool. :unsure:

It'll take forever to fire up mate. Did you fill the new filter with diesel before fitting it? If not you've not only got to pump air out of the lines but also the whole filter full of air too. Theres no manual pump on them as they are self bleeding by cranking the engine.

Your best bet is to draw fuel through the return at the pump.

I'm having the same problem. The computer is claiming there is an "engine systems fault". Again a 1.8 TDCI.

I didnt fill the filter when originally replaced. Since seeing this post I've filled the fuel filter prior to cranking. Still no joy. I'm fairly certain that there is air in the system.

I get the impression that the fuel pump isnt trying to draw fuel from the filter. After removing the fuel pipes from the filter housing, there is no diesel evident. Also, the "engine systems fault", appears at stage 2 ignition. Any suggestions?

How would i go about drawing fuel via the fuel return line?

Thanks.

Yup, they will only fit on one way anyway, due to the length of the pipes.

Hi, you cant get the pipes wrong as there sized and only fit where they came off. you will have air in system still, try cracking open 2 fuel injector pipes a little then turn engine over untill air and diesel starts coming out of injectors, turn engine off, tighten injectors back up and should start.. may take some turning over still though so you may need a jump off another battery.

been there meself!! just the once! :)

Hi everyone, I have a 2007 1.8 tdci Focus Sport. To solve the problem of bleeding the fuel system. I had this problem after changing the fuel filter and resolved it by using a syringe bigger the better 50ml if you have one. Fill it with diesel then pump it down each of the feed and return pipes that lead into the fuel filter, careful not to spill any. Once you have filled each pipe carefully attach it to the filter body. Start your car and keep it turning over, it took mine about five to ten seconds. It worked for me.

Id just like to add to the above comment that I made that you'll also need to refill the fuel filter body as well.

Just got a 1.8 mondeo going that had run out of fuel easiest way I find is to top  up filter then prime the line to the pump with a small syringe might take a few attempts but you won't be there hours

The time delay just shows that this is a long term problem with the 1.8TDCI. I had a lot of trouble last filter change.

I think one problem is that the fuel tank pump is either not present, or not working, on my car, and maybe on others. It is reliant on the 1st stage of the main diesel pump to pull fuel through, and this pump will Not suck air. It has to be primed.

I resorted to a jam jar with pipes connected through the top, and a hand operated pressure pump to ram diesel into the filter inlet, as hard as I could. Then there is the problem of re-connecting the inlet pipe, as soon it is disconnected ( to remove the priming kit), the fuel just whizzed back down to the tank, leaving a pipe full of air. I then used a vacuum pump (I happen to have one, part of my job!), to suck the air out of the top vent port on the filter. Took best part of two days to re-start.

BTW: I really do not like doing anything on the filter outlet side, like filling the pipe. I known what the sizes of some of the holes and ports in the HP pump & injectors are like, and Any dirt (even invisible) downstream of the filter could be a real disaster. All the HP (>20,000 PSI) diesel bits, like pump, pipes, injectors, are a very expensive and critical part of the car. Best left undisturbed if possible!

A permanently fitted priming pump or bulb on the filter inlet would be a very good idea. Anyone done this on a 1.8TDCI?

There is no fuel tank pump on the 1.6 or 1.8 TDCIs.  Well that's not strictly true, there is a pump, but Ford don't use it.  The fuel is sucked up by the High pressure pump before being sent to the rail.

Just fill up the pipes and filter with fuel, connect it all up, job done, (use the filtered fuel)

Wait...there's actually a pump in there?  Sure it's not just an empty pump casing with the level sender?

Mine was, of course it might have been a replacement but the sender unit definitely had a pump in it, the replacements have the pumps so either ford have the pump and don't use it or its a replacement in my car
