What loom and ecu have you used

got fuel in the tank? it happens lol
with the flat battery, to be 100% get sum1 to use jumper cables to it see how you go then

seems you changed to vs loom and probably havnt got the bcm so the security is on stopping it from running cause it cant see the bcm why does eveyone change to vs loom its so easy to connect the stock loom to the engine and run it.

2 fixes for your problem
1 get a custom memcal with the security stuff removed
2 use the vp harness and sensors to run the engine.

hey me again um yes i have got fuel and ran jumpr leads before i askd these questions but help is much appreciated,and i alredy used the vp loom as i thought the same as you mate! and how do i get a custom mecmcal and what is it lol?

[delcowizzid]

if you ran the vp harness you allready had in no it should just fire up.i presume you have added the inlet airtemp sensor into the inlet manifold somewhere need to get a hole drilled and threaded and changed the coolant sensor as well as they are different too you can buy an adaptor to put the VP sensor into the VS engine.it will need a tune to suit the ecotech though in the end .but it should fire up and run ok.
