2005 XC90 Died on hwy, fuel pump?

Post by Skenda02 » Thu Sep 13, 2018 8:00 pm

Driving to work yesterday morning, car died when I came to complete stop. All lights came on dash then they all turned off. Not triangle warning sign, nothing. Had it towed home. Not throwing any codes. Turn key and it cranks but won't start. Pulled cap off fuel valve, reservoir empty, there was no fuel to release. Took gas cap off, can hear fuel pump engage when turn key on. Pulled a plug and I have spark. Shot starter fluid in intake and it started then of course died. Pulled fuel line from fuel filter on both ends, tried to start, no fuel pumping out. So can my fuel pump be bad even tho I hear it run? I might add that when the car is cold no matter the temp or time of day, if I don't give it gas a couple times before putting it in drive, it will choke and try to die when trying to drive off. This started a little over year ago. Took into Volvo to replace timing belt and told them about it, they charged me another $2500 to drop oil pan and replace a sensor. After getting car back, it still chokes if I don't give it gas before putting in drive.

Could you identify which engine you have? I think 2005 had three available (I5, I6 and V8). What is your mileage?

Yes the fuel pump could be the issue even though it appears to be working.

Do you have a fuel pressure gauge? You need to check actual pressure at the rail to see how the pump is working.

The pump can run and not build sufficient pressure. What you are experiencing fits this type of failure.

At those miles the pump has done well. Two options, 1) change the pump and filter and bet you made the proper diagnosis or 2) get a fuel pressure measurement.

As far as I know there are no sensors in the oil pan of your car. So I don’t know what the dealer did and charged you for.

Repair only with used parts this time, it will get too expensive otherwise (can get parts off Ebay)

There are fuel pressure sensors that go bad (FPS) and also fuel pump controllers (PEM) - google up a bit. All cheap used off Ebay or on sites such as fcp, ipd. The fuel pump is solid on this car but you never know, maybe it was already replaced with some aftermarket part. If replacing, keep away the old one. Again, get used parts, or it will cost too much to guess.

..Running fine/no issues then seconds later died with no fuel pressure. The pump runs (obvious buzz/whine that sounds normal?) but zero flow from the hose at the inlet of the fuel filter. Sounds like one of the hoses on the pump assembly inside the tank broke or came loose. Depending which one, either the pump is sucking air or the fuel is spraying back out into the tank instead of out to the filter/engine. My vote is the pressure hose that jumps between the pump outlet to the top plate (and out to the filter/engine).

No pressure at rail. Was bone dry.

Replaced PCV Box said possible pan was clogged, replaced boost pressure sensor

So..... several weeks later, after receiving the wrong fuel pump and finally getting the correct one, that did not solve the problem. Again, the pump is running but if I disconnect the line at the fuel filter and try to start the car, no fuel is coming out of the line and if I connect it back to the fuel filter, there is still no pressure at the rail.

Fuel pressure sensor may be on the gong. Bosch 31272730 is the part number.

Also as mentioned by Oragex the PEM can be at fault. It's possible it still supplies voltage but not enough current. Time to test with a load PEM such as a test lamp with at least a 21W globe.

FPS is a 10 min fix. Would start with this first - use vaseline on the seal before inserting the new one

Easy to check the PEM for corrosion Again any used clean looking unit from Ebay will work - $100
