No Power to fuel pump, no spark, turns over. Seriously confused

I am having exactly the same problem. Changed to a known good CPS...no difference. Fuses all good etc. I might try changing the underbonnet fuse box complete and see if that cures it but it is very strange...first thing i will check wiring from CPS. Did any of you guys cure your vehicles non start issues? Posting updates helps others. Even if the trucks ended up at the junk yard at least we get the idea that 14 year old vehciles with printed circuit boards are not a good thing...

Cheers

Year of vehicle? Is it petrol or diesel?

Read the VERY FIRST POST ON THE PAGE!!!

Do you have spark?

What is the fuel pressure?
