I've got a problem with my cosworth I'm not getting enough power to my injectors. The plugs are reading 0.1v whilst cranking. The injector relay clicks on ignition,so it has power. fuel pump primes.etc
I'm running a 2wd engine loom and a L6 ecu with a chip

 

bad earth on intake manifold

 

Cheers for getting back, ive checked continuity between the earths on the loom and chassis thats fine. Is there any other checks i can do? could the earths still be bad? cheers, really can't get my head round this one

 

try

www.bigturbo.co.uk for the wiring diagrams it may help a little

I'd change the relay and fuse and check voltage at the ecu

Relay and fuse fine, ecu has voltage. It's very strange i can't work it out.

 

so its a non starter ?

if so you need to check Phase sensor and TDC sensor

This is not an earth problem, at the injectors when ignition is on you should have on 1 terminal(each injector) 12V LIVE, permanently, the earth at each is pulsed as needed by ecu, so see if they are getting pulsed or it it's the 12v dissapeared, if so temporarily reinstate it then try.

hi mate, did you have any luck since this is the same problem im having? cheers hugh
