Alright Guys!

Getting proper fed up now! For a year I havent been able to start the cossie, in between work and stuff I havent had great amount of time to look at it. Basically, a year ago I took it for a drive and it just died on me. thought it might have been the fuel pump wiring but after replacing the relays etc i've checked with a multi meter and there is power getting to the fuel pump. I've also checked the injectors and there is power when I try and crank it over but it just doesnt fire.Anyone have any ideas on what else it could be? A couple of times last year it di d fire up then cut out again after 10-15 mins. Was thinking this morning about changing the Fuel filter incase its blocked, but anyone with any ideads? Desperate to get it up and running for my wedding which is in 7 weeks!!

id check the pump first mate mine packed up on me a couple days ago there was a feed etc just the pump was faulty.

remove the ignition lead from any go the 4 cylinders put a screw driver in it put it across a ground crank the car see if theres a spark mate.

Could possibly be a phase sensor or crank sensor also. What model of Cosworth is it? I'm local I could possibly come have a look when I get a chance.

Fuel cut off switch in boot to is worth checking!

The fact there is power at the pump means it should be running?

Always verify the ignition system before looking elsewhere, i.e. is spark present at one of the leads, as said?

The injectors will always have power with the ignition on!

Had the same problem with a fuel cutoff switch Wel specifically the multiplug in it and the fuel pumps loom. Took fucking ages to find

Also the 2 plugs on the bulkhead panel give trouble on 4wd's.

Dont think I have a fuel cut off switch any more as it was rewired previously, i just seem to have a relay which I have checked and changed.
Thanks mate, again I appreciate that! Nice to know there are lots of helpful people around!

will have a look on the weekend and go from there. Will check the ignition and if I have a spark and go from there.


Thanks everyone for the help so far, very much appreciated!

welshcossie

will check them also, thanks mate

If the switch was open the pump would not have power!

run the pump with another battery so to be 100 percent sure the pump is working, remove a lead put a spark plug if u see spark then ok try it to all 4.make sure distributor cap is ok,check inside cap a small piece of metal that touches the rotor arm .rewire pump at any case!! check current at the injectors check coil for good connections. my cosworth cuts off when i remove the water/cold start temperature (blue)
