just after some help.my vl calais had a rb20 motor in it,since then i have took the rb20 out and put in a stock rb30 motor in.its all wired up and trying to turn over but some reason the injectors are not work.im sure its the injectors i took a hose off and sprayed some deodorant in it and it runs.can any one help me or no what it could be cheers

The RB30 injector feed comes from the body loom. Maybe this isn't connected? There is a 4 pin plug at the front of the inlet manifold, an orange wire in this plug is +12v from the reverse polarity relay.
