Unfortunate new Volvo owner! (98 V70 AWD)

[Culito]

I guess we'll see what happens. The pump that came out was a Walbro dated 1997.
The DW pump looks like it has a different shape on the pickup end.

[abscate]

The AWD pump is completely different than the FWD pump in both Mounting and pump performance

It delivers near 70 psi to provide the ejector function

Walbro is OE and the TI group builds the Walbro pump, available at link above

So I have the dreaded ETS. Can't find any recent posts.
Had some could replaced.
Cleaned the sensor and the throttle body. Didn't help with the acceleration. Throttle body has not been replaced. Codes at the auto parts store are p 1027 and p 1053. Do I need a better scanner? Mechanic said there were no codes after they replaced the coils. Wondering if I should try to replace the sensor first? Is there anybody in the Bay Area that can run some codes?

I don't know how to help ya there bud ^^

This pump definitely looks correct for the AWD housing - now the question is if the new cheapie pump housing is the same as the original, which I trashed.

Maybe this weekend I'll tear back into it.

In other news, I figured out that my cruise control not working is due to the brake switch. It is adjusted correctly, but the cruise doesn't work unless I pull up on the brake pedal with me toes.

I also got some new rotors (that have been sitting for 9 years) and calipers from a friend, new sport springs, and some misc parts.

Please let me know if the drop-in replacement pump fit inside the PPS housing! I'm in the EXACT situation you're in right now!

Welcome to our world Culito. I'm less than 2 hours from you and have a driveway full, though no AWDs.

Your Pro Parts AWD pump is super noisy?
Mine is still working, but it has developed a bit of a hot start problem where I have to crank it longer than usual before it starts.
Not sure if that's related to the pump or not. I'll pull the pump back out soon regardless because it's driving me crazy.

Check your fuel pressure first and see what you are getting. For -98 years you are looking around 43 psi, when ready to start and it might drop off a bit when running but should still be up there. Also check the pressure when the car is hot and see what you are getting.

How long does it take for the pressure to bleed off once the ignition is switched off?

So I dug into this fuel pump thing..again. I never did check the pressure / bleed of the Pro Parts pump.

In short, to fit the new Walbro pump in the Pro Parts housing, some modifications are required.

The Hole of Shame: I had already cut this open, replaced the pump, and tacked this thing shut (sealing the rest with silicone) once.

Disassembling the Pro Parts pump:

Walbro pump on left. Note that the side inlet on the bottom is clocked 180deg out from the PP pump.

This required cutting a slot opposite the original on the inside "sock". No big deal.

Once I sat the pump in the housing, it became apparent that the bottom inlet facing the other way was a problem. I had to shorten it a bit so it wouldn't hit the side of the housing. I trimmed around 1/8" off the length. This inlet doesn't seem critical, as most fuel will come from the bottom sock.

Now the fun begins. Note how much longer the Walbro pump is compared to the PP.

The Walbro top assembly with the "nozzle" can be removed from the pump. I transferred the o-ring, nozzle, and split sleeve from the PP pump.

Note that the PP pump has a space inbetween the two terminals. The PP nozzle fits in here. I had to trim a bit off the bottom of the nozzle to fit on the pump. (final assembly not pictured, oops)

Leftover parts: Junk pump, Walbro nozzle, O-ring, sleeve, and just the tip of the bottom inlet.

When placing the nozzle on the pump outlet, just make sure the sleeve doesn't push downwards. Now the unit should snap back together.
The Walbro electrical connectors were funky, so I just soldered and shrink-wrapped the wires to the inside terminals.
Upon re-assembly and first test, I thought the pump wasn't working, but it turns out the Walbro pump is whisper quiet and the tired ol' 5-cylinder fired right up.
The downside: the pump is so quiet that now I can hear all the other disconcerting noises the car makes. What was that grinding noise?!

The are cool white with a built-in resistor for 12V operation. I drilled the center of the bulb holders out to pass the wires though, stripped & tinned the wires and wrapped them around the holder in the slots for the original wires. They're nice and bright, and dim nicely with the controls.

Next up is the same deal for the shift indicator light.
