Default saff 4x4 dying when warm now fixed.

Hi all, You may remember a few weeks ago me writing and moaning about my car choking and dying when warm.
After changing ect ats map and phase sensors and checking all resistences and so on, Its finally fixed it was the fuel pump, put new uprated 1 on and all is fine again yeha after 8 wks of head scratching.
When i bought the car it had a crushed fuel pipe at the front where some dick had jacked up on it, so maybe that made the pump work too hard.
I changed the pipe and all seemed ok till i took it on the track after taking it to stg 3. Just goes to show its not always so obvious to find these faults.
Big thanks to all who helped. cheers steve

You need 13v at idle, rewire the pump, its better to be safe than sorry.

3rded - rewire the pump. If you've got 13.8V (ish) at the battery at idle, 11.8V at the pump suggests that the current wiring should be upgraded.
