hi folks does anyone know what would cause no pulse at the injectors on my cossie? ive got fuel up to the rail ive got a good spark ive got all the wiring plugs on the correct way. i do have power at the injectors but will not pulse when cranking its got me baffled! any help on this will be greatley appreciated. thanks

 

anybody have any ideas? cheers

 

Is power present at the injectors?

Have you got your earths all on with good contact

 

hi lads yes i have power at injectors but they just wont pulse. i have X2 brown earths which are bolted to my inlet manifold how many more is there mate?

 

Verify the the Phase sensor output is ok...

Martin

 

im not sure mate i will be checking that tomorrow morning and il report back to you, thanks for the replies

 

2wd on the throttle bracket and 4wd on the back of the plenum ,two on the same connection .
Check if you had the wiring loom disconnected that you have the plugs on the right sensors as they can be switched easily enough

 

I have put a new crank sensor on and its now pulsing but very weak it juat manages to light the bulb. still wont start. Fuel pump is working and got a spark. Cheers

 

The car now tries to fire but will not start grrrr!

 

the phase sensor wiring looks rough as f:@k also would this stop it from starting up and getting a very weak pulse? also when i first crank it over it will pulse bright then immediatley dim to the point where its barely visible.

 

one more thing, when i use the test light on the X2 injector wires they are both constant live is this normal? ? with (ignition on)

 

Definitely stick a new phase sensor in it mate

 

will do mate got one on order cheers for that .)

 

so do you rekon that a knackered phase sensor would cause a weak pulse?

 

New phase sensor fitted No change any other ideas?

 

Ok its burst into life but only running on cylinders 1 and 3. The other two cylinders are sparking and pulsing but wont fire.

 

Are all four lugs intact on the crank pulley, do you have fuel to those cylinders?

The injectors have a permanent supply, re your question, so this is correct.
