Hi all, sorry if this is redundant. I'm a noob, but could use some help. I'm trying to keep my TTA stock (I know, I know). Has had very intermittent hot start issues since the day I bought it. Finally brought it to a Buick dealer, and they said fuel pressure dropping as car warms up, and to replace pump.
This hasn't solved problem, but I'm going to choose to believe that fuel pump needed replacing. Problem is when I looked on my invoice they installed PN: 25116154, which shows as pump for GN/GNX Buicks. When I research, I'm coming up with PN 25163473.
Is there a significant difference in the pumps? should I make them redo?
P.S. Would welcome any comments on the start issues. It randomly just won't turn over. Has a new starter, alternator seems to be fine, good battery, I don't know of any VATS issue...
