Feul problem new feul pump still not starting?

Be sure to check the main relay and fuse.

Lots of things could cause a no-start, Hendrik. Is your "Check Engine" light on? If so, please have someone get the OBD error codes from the car's computer.

Does it crank but not fire?

If it doesn't crank, check the battery condition, battery connections, ground connections to frame and engine block, starter solenoid, starter motor.

If it cranks, doublecheck your fuel pump installation. Make sure the new fuel pump is properly connected and properly electrically grounded. Look for a fuel pump fuse. Check for proper fuel pressure at the fuel rail, check the fuel flow rate. Check for spark, check or replace spark plugs, distributor cap, rotor, plug wires. Check valve timing, replace timing belt or chain if necessary. Check compression.
