What did you do to your Volvo today? Topic is solved

[abscate]

1998 1999 2000 will take the 9480152 Volvo fuel pump on a FWD vehicle.

Replaced the fuel pump on the 98' S70 yesterday after confirming that there is no fuel pressure. The car still won't start. And yes, I dropped in another good pump relay before.

Did you give the pump time to prime?
A full tank may help priming.

Thank you. I tried cranking 3 times and for pretty long. It never took that long when I replaced these pumps on P80 non canbus cars in the past. Tank is actually full.

Today I took some time to look further into this. First I confirmed that there was power at the pump. I never knew that the pump only gets power when cranking, I thought it would come on when the ignition is in pos 2. But maybe canbus P80 does that, not sure.

So power was there but I was not able to hear or feel the pump. Then I took the pump out again and put power directly to it, and there was nothing. Looks like a bad brand new pump. I looked over the installation instructions again, because this was the first time I replaced the actual pump in an assembly. Can't see anything wrong though.

I need to get this car moving again soon, so maybe I can temporarily use the pump from the non running 99' S70. Need to get confirmation if that's the same pump.

We call it a fuel pump relay, but it is truly a fuel pump controller. It starts the pump in key on, but won’t stay on unless it detects a ~ 50 Hz signal from the ECU? Indicating the engine is running.

Covered in great detail, worthy of a Tomy Award, from Mr Al in NJ, here….

Thanks Abscate,
But I already confirmed that power comes on at the pump when the key is turned. So the fuel pump relay works just fine. I got the new pump yesterday, a Bosch unit this time.

We expect a running car tomorrow am, we have standards to keep here.

I got it running today, but unfortunately it was in the afternoon. Sorry I missed the standard
This pump looks like a decent quality option with some modification. Write up to follow.

Prepare to be judged.

Whoever says Oetiker clamps belong on every hose in the car might be a little bit of a silly billy. I spent two hours replacing the turbo coolant hose on my S70, when the same job took me 20 minutes on my 850. Yuck! What an awful place to have them in that spot. I couldn't get any tool in my box on there with any sort of relative ease.

They're perfectly fine on easily accessible hoses. But on that coolant elbow on the turbo? No thank you!
