s60 2006 t5 stalling

volvomadness · Post by **volvomadness** » 28 Aug 2020, 17:08

s60 2006 t5 have replaced fuel pressure sensor and fuel filter.

Car runs rough (idle bouncing) on initial cold start then smooths out.

Drives fine plenty of power but occasionally will lose power and stall. Feel that it is fuel related since if i feather the gas it will recover (not always). Starts right up but will stall a few times as I begin to drive and then everything is fine.

Also the gas gauge doesn't always work.

I suspect the fuel pump but hope its not. Since its intermittent don't know if it can be tested. Is there a fuel pump relay for these cars?

Any thoughts on how to proceed?

How is the PEM ? May also want to check the grounds around the engine (small wire behind the engine cover), near battery, small wire at the starter, same at the big rad fan connector, maybe test the alternator

You have to diagnose fuel pressure with a gauge, either rented or bought?

How close are you to me in 12054?

Will check grounds. The plugs are brand new. No codes. Just try bg treatment let’s see if this helps engine flush and fuel system cleaner
