ZTT non starter any ideas

[doctor.g]

ztt xpower 2.5 v6 petrol turns over but will not fire, changed fuel pump (common) any ideas?

Have heard of a retaining clip breaking (assume locating or connecting the fuel line into the tank) solved by dealer fitting a new stronger clip.

sorted, it was the valve on the side of the other pump (the one with the fuel filter in)recirculating the fuel round the tank, and not sending it to the engine.
What a place to put the fuel filter, under the back seat inside the tank. AND NO DEALER DIAGNOSIS REQ
