Need help
got a VS commodore, ive changed the DFI, coils, changed the CAS, tank is 1\4 full. changed the fuel filter ( the buttons on the keys are missing dont know if that would help) took the sparkplug out and shes sparking...
is there anything im missing? shes turning over but not firing up
are you sure it's getting fuel?, sounds like no fuel to the engine if it wont turn over and u got spark, check your lines from the fuel pump to the injectors and make sure you don't have a kink in the line or if you've got something blocking it.
also when you turn the key to the on position can you hear the fuel pump turn on and prime the system?
yeah im pretty sure its the fuel pump thats humming

It should only hum for 1 - 2 seconds....just long enough to prime the fuel line....then it turns off till the engine starts and oil pressure comes up.

best bet i guess is to buy a new one... another question... how do i check the fuel lines to see if there blocked.. take them off ect??

Fuel lines will not be blocked as there is a filter just in front of the fuel tank and the fuel lines just never block up. If you want to know if there is fuel pressure just loosen the clamps on the fuel filter and see if fuel sprays out - be careful and don't get it in your eyes! You could also loosen one of the injectors to check. If no fuel squirts out with either of these check then it would be a fair bet to say the fuel pump is not working, however that may be due to a relay or fuse or connection being faulty. Do either of these within 5 mins of turning the ignition off.

if the fuel pump is humming like you said when you turn the key to "on" then the fuel pump sounds like its working. maybe your injectors are stuffed
I would highly doubt that all the injectors have packed it in at the same time. even with 2 bad injectors the car would be getting enough fuel to fire but it would idle rough as hell.
What happened prior to you changing DFI, coils, changed the CAS, tank is 1\4 full. changed the fuel filter. Did it just suddenly stop???? or was it running rough?????
Easy way to find out if lack of fuel is the problem of the motor not firing. Grab some aerostart and give it a spray into the throttle body with the butterfly open and then crank the motor over. If it fires and then dies then lack of fuel will be the problem.
Another thing that can be overlooked is when you changed the coils is there any chance that the leads have been put on the wrong way? As that would explain if you have fuel and spark but the motor wont fire.
