Fitted new pump as I'm going BPU, already have 3" decat, 3" catback, restrictor ring and colder plugs so thought I'd take it out and see what it's like .....drove off boost for a couple of miles to the bypass and then put my foot down for it to start spluttering and then die, I managed to roll to a safe place where I suspected it may have been a fuel issue as I was on empty and it happened going up hill but then it fired up so I trundled to the fuel station and filled up, coming back up the bypass I put my foot down only for it to splutter and die again but it fired up again on the turn of the key so I trundled home and took the pump out again to check it was ok, I changed the filter on the bottom of the pump and re soldered the wires then put it back in and took it out again....back to the bypass off boost then after putting my foot down it spluttered and stopped. I coasted to a lay by but it would not run, it would fire up and then die, eventually I managed to get in touch with someone to bring me some tools so I could take the fuel pump assy out of the tank and for them to drive me home where I refitted my original pump and then drove me back to the lay by where my car had started to attract attention but luckily it was still in one piece and after refitting the pump and sender assy in the lay by it fired up first turn of the key and now runs sweet again.
Please can somebody tell me what I did wrong as I'm sure it was fitted correctly, is it the pump thats faulty? Yes it's a brand new pump.
Would just like a few opinions before I contact the seller,
Thanks.
