Hi

I changed the fuel filter a few weeks ago and all was well, had it ticking over for 10-15 mins, Went to start it again today and now it not start
It will fire the once but thats it. Any ideas?

Cheers

I'm having similar prob with my s1 drove it all afternoon then cut out on me and won't start again checked all the obvious

How much have you checked guys, spark etc and i will hopefully be able to guide you to fixing it ! (dont worry i know what im talking about !)

I feel for you mate, I might get mine off the drive one day lol

90spec_RSmith

spark is fine mate, All was well until I changed the fuel filter

Fordmad!

Id check to see if filter is blocked. Is the pump priming...

90spec_RSmith

Brand new filter so it shouldn't be blocked, yeah the pumps priming. Just seems very strange as I had it ticking over then i go to it again and nothing....

Have you had a mate try pressing the metering flap as you try start it, i think it is due now to the metering unit needing setting up as if your OLD filter wasnt letting loads of fuel threw and your new one is, you could be flooding or starving the engine

You got it running mate if not do you need a hand???

I'll get the missus to hold the flap down for me 2moz, I was going to take it for a set up soon anyway as it was holding back on boost plus the old filter was leaking so i fort that might of been the culprit

In a way it is mate, I own a garage and work on all sort of fords every day so just drop me a PM and we will get it going for you, i should spend more time fixing the cars in my garage than been on here lol

I'll give the flap a try 2mz and if it dont work I'll drop you a pm

The engine ran some time, you turned it of and now - a few weeks later - it won't start?

Spark's ok you said.
Fuel pump primes, but does it run when you try to start? -> Fuel pump relay fault. Don't think it's the signal from dizzy or ECU because ignition works.
I don't think the new filter causes the problem. When the old one would have been too restrictive, you already had the problems when you changed the filter. And the car would have caused problems with the old filter.

Next step is to check the fuel system. Easy with a pressure testing equipment

If he changed the filter the fuel flow could have changed mate, doesnt take anything at all to change the MFI fueling even a little adjustment will change the starting of it etc, we had loads at ford like this when i was there

Tried the flap down trick 2day and ended up with a flat battery, guna give the battery tray a lick of hammerite while the batteries out.

I think your right about the fuel flow as the old one was leaking alot, So now its probably over fueling.

Cool you have the answer now your over fueling, turn the adjuster on the metering unit (alan key) one full turn anti clockwise then very gently try the flap, it only needs about a milimmeter at a time until it fires, if no fire after a few seconds back the screw again and then do the flap again, once its fired i will tell you how to set fuel which is very easy with a C0 machine for a trick we used in the old days that will get it bang on

90spec_RSmith

I got it started, Just adjusted the idle screw a little bit and it fired up not sure how its guna run but it will go for a setup soon

Good man hope it was some help

Sure was mate, Nice one
