Fuel filter priming problems
Discussion
Okay so decided to change my fuel filter on my ford focus 1.8tdci and bought a priming pump do it, i changed it filled the housing up with diesel and cranked it it started for 5 seconds and then cut out which i was expecting due to air in the system, so i connected up my handheld priming pump/syphon and it’s pulling fuel through and into a container but doesn’t seem to be pulling enough through everything was air right, anyway i give a good pump for a couple mins and then try crank the engine and still nothing. Has anyone got any suggestions on what i’m doing wrong as i’m really stuck

Does that filter have a separate O ring seal, and if so are you sure it went back in the right place?
Any fault codes showing?
yes made sure it was the right way, put it on the bottom instead of top as i read about people putting it on top and it not working, no fault codes at all Any fault codes showing?
king my car up by turning it over too much, probably gonna toast my starter motor Hammer67 said:
Did you fill the new filter with diesel? If not, take it back off and fill it up.
Whenever I have similar problems I use an air powered brake bleeder to suck fuel through.
yeah i’ve filled it up multiple times now, when i go to bleed the system it seems to just suck the fuel up out of the housing only, i’ve watched youtube videos and i’m doing it exactly how they’re doing it yet there’s works like a charm and i’ve been trying to get mine started for 3 hours now Whenever I have similar problems I use an air powered brake bleeder to suck fuel through.

Weird, you "could" try cracking off the feed pipes on the injectors whilst cranking. Investigate if that is safe to do on your engine first. Worked for me once on an ancient Golf TDi that had the same problem.

what will this do? will it just pull any air bubbles out of the system Worked for me once on an ancient Golf TDi that had the same problem.
Squirt carb cleaner into the intake whilst cranking the engine and it will start up, keep it going by squirting more carb cleaner in as necessary
.
Eventually the engine will run by itself as the air is purged out and thats the job finished.
Not strictly by the book but sometimes needs must.
I have seen people tow a car for miles after a filter change before it would start
DO NOT use EasyStart!!

Again, make sure this is safe to try on your engine.

i’ve heard people spraying deodorant in the intake to get it going and it working but i know i definitely won’t be spraying deodorant into my car, i think i’ve finally given up with it and going to call a mobile mechanic tomorrow. At least now i know to NEVER change a fuel filter again, seems as if some people get lucky and it starts first time and some people not so lucky .

This is a common problem with the Focus and most Fords, you need to find the return pipe and use your priming pump to pull fuel through the return, it will start no problem after that.
Okay i’m having to scrap the mechanic and give it another try anyway so i will definitely give this. a try and cross my fingersGreenV8S said:
Doesn't that suggest something isn't sealing? I assume you do actually have fuel in the tank and it isn't just sucking up fumes.
yeah fuel is in the tank and i triple checked everything was properly sealed, only thing i can think of is i connected the syphon pump to the wrong connection but i followed a youtube video and connected it the exact same place, sorry i don’t have any technical terms for the connections
Don't start flecking around with the injectors or anything on the high pressure side, you've simply got air in the low pressure side which needs removing, you just needs to keep drawing fuel through, the correct bleed nipple is the one on the top of the housing.
If you've got a mate on hand you can crank the car with the bleed nipple open but shut it closed before the cranking stops or it'll suck air back in, that can speed things along. But it's just a case of using your hand pump and keeping on going until there's no air left.

yeah i noticed the little bleed nipple but wasn’t 100% on it, i will give it a try but i also found something online in the ford user manual suggesting to connect one end of the pump to the fuel line on top of the housing and the other end inside the return pipe so i will also give that a tryIf you've got a mate on hand you can crank the car with the bleed nipple open but shut it closed before the cranking stops or it'll suck air back in, that can speed things along.

i have a 2007 ford focus lx estate 1.8 TDCI an after changing my filter i had the same problem followed everythin that people have been replying with an sat there cranking for a very long time but still didnt start
now ino i shouldnt use easy start but after spraying at few times an it fired an vut out agen i just cranked it on its own without the easy start after 2-3 time it started right away an all back to normal
much quicker an easier
