Gti 8v digi rough running

[Craigwilson]

My gti 8v digi has just started running really rough when it ticks over it jumps about and sometimes cuts out then wen i rev it it kina hesitates untill it pulls through.

Its had:

Plugs
Leads
Dizzzy cap
Rotor arm
Coil
Idle stableisation valve
Maf
Ecu
Ignition switch

Any ideas ?

Fuel pump?

[Craigwilson]

To be honest i did suspect that but which one the pickup or the actul pump because the actual pump is only a few years old the pick up is origional.

Might be worth trying a coolant temp sender.
