If you have an engine warning light fitted then wouldn't a paperclip test bring up an immobiliser fault if one is indeed fitted?
I had a problem back in the early running days of mine where I couldn't get the fuel pump to run from the ECU. So I wired in a seperate circuit to energise it when the ignition was turned on. The engine would then start after a few hesitant turns and usually plenty of backfiring when attemting to fire from warm. As all the position sensors were new when the engine was fitted I was reluctant to start replacing them. I took it to a garage where they replaced both cam and crank sensors and this cured the fault. After a few days I undid my earlier bodged fuel pump feed and since then it has been fine (running up the fuel pump in advance of cranking).
In short my ECU wasn't firing up the fuel pump because it knew in advance there was a problem with one of the position sensors (probably crank) - sounds wierd!
if its an immobiliser fault and the em light is wored up correctly then it would constantly flash on turn over.
But as perviously ruled out it cant be that.
Sorry mate, i'm not ignoring you at all.Originally Posted by ck
There is a live fuel pump wire down at the relay, so there is power down their. Also the EML light is wired in, and it stays on whilst cranking the engine. I assumed this doesnt go out until the engine starts, same as my cavalier SRI.
I've tested my ECU in a friends cavalier turbo and it works, and he has given me another fuel pump relay which we tested first. I'm just waiting on a crank sensor next to try.

Yeah they all stay on until engines running,
Don't know if this would help, but with my car one of the lamba sensor wires which T's into to the Fuel pump wire in the loom, or power to the relay - can't remember, was earthing during cranking, so stopped the pump from working.. So disconnected it, and the pump works
Although this wasn't the main thing stopping the engine running (as I had bridged the relay), it was something that needed sorting..
maybe of use....maybe not...
