hi i have had my e30 325i for about 6months and i have been building her up.got to the stage were shes ready to get fired up and she wont go.i have no spark no fuel.if i bridge the relay fuel comes up if i live the fuse fuel come up but wen i turn the key nothing happens.also no spark i checked the coil theres no live or no earth on the terminals when ignition is on.i think that the two problems are caused by the 1 thing.if anybody has come across this problem or knows what might be wrong with her plaese reply.

thank you.

OP says there's no 12V+ on the coil with ignition on.
12V+ to the coil comes straight from the ignition switch - nothing to do with the ECU, relays or the engine loom at all.
