Died while driving, no start, 2003 Volvo V70 base wagon 2.4l, 285,345 miles on the car, 90% interstate highway.

Intermittent shutdown for the last 17 months.
The first time was assumed to be a six year old battery.
Nine more intermittent shutdown, until magic #10, and it has not run in three months.
Initial diagnosis: No pressure in fuel rail, pump not running.
Due to miles and vehicle age I assumed the pump was bad.

With my current health issues it has not been a priority.

In the past three weeks a friend has replaced:
#1. Fuel pump.
No signal from CEM to fuel pump.
Dropped CEM under driver dash, no sign of corrosion or water intrusion.
#2. Inspected / tested all related relays, shunts, fuses, and re-seated them.
No signal from CEM to fuel pump.
#3. Fuel pump relay.
No signal from CEM to fuel pump.
#4. Cam position sensor.
No signal from CEM to fuel pump.
#5. Saturday April - 8 2023 the crank position sensor will be replaced.
Early stages of crank position sensor failure on most vehicles = random overheat fail, cool down function cycle, eventually leading to total failure = no signal to ignition or fuel pump.

If that fails, I will invest in the Volvo VIDA DICE OBDII Diagnostic Scan Tool.

Advice or suggestions welcome.

Use a low cost scan tool to check for codes. If you do not have one, go to one of the many parts store that offer free code reading.
Has the Electronic Throttle Module (ETM) been replaced? It would be well past typical failure miles if it has not been replaced or up graded to contact less type ETM.
Has the car had routine maintenance? Many things could fail at this age/ miles.

If it has a PEM, the signal comes from the ECM,
I believe the PEM commands pump when ECM grounds the PEM,
the PEM gets constant 12v.

My thoughts too Jones but I think the 2003 has no PEM and the pump is always run at full demand. No FPS either.

I feel like someone else had this same issue before. Any possibility it’s immobilized or something to do with the key?

immobilizer stops cranking on mine.
Whatever system it has should still be able to read fuel pressure somewhere.

Thanks for the feedback.

Update: New crank position sensor just installed.
No PEM on this car.
The immobilizer and key did not occur to me, will try resetting security with the key, and pulling codes.
NO, the Electronic Throttle Module (ETM) been NOT been replaced.

I have been catching up on maintenance with "NEW" parts for three years:
#1. PCV.
#2. Coil packs, spark plugs, air filter.
#3. Ball joints, tires, alignment.
#4. Four strut assemblies.
#5. Driver master window switch.
#6. All fuses replaced.
#7. Headlight and tail light bulbs.
#8. Removed garbage jammed in driver seat track.
#9. Cleaned throttle body.
#10. Power steering reservoir and hose.
#11. A/C compressor.
#12. Serpentine belt.
#13. Water pump, tensioner, timing belt.
#14. Brake pads, rotors, and master cylinder.
#15. Battery.
#16. Left rear tail light lens assembly.
#17. Rear hatch assembly.
#18. Left, right front axle shafts.
#19. Engine oil changes with new plastic cap, as needed.
#20. Wiper blades every year.
#21. coolant temperature sensor.
#22. Radiator.

Thank you.

OK.

No codes.
Reset security with key and fob.

Cranks but No start.
No fuel in rail.
No signal to fuel pump.

Thank you.

Just wondering...

How do you know your 2003 does not have the PEM?

well if it cranks its not the immobilizer.

No fuel , no run.
Fuel pump relay is where I'd look first, pulling the seat is a chore on the wagons.
If you pull the seat you have to disconnect the battery, but you cannot reconnect to test for power at the pump without setting a SRS code, then you need a decent scanner or vida to erase it.
