My V70 when cold will never start on the first attempt. I can let it crank for 20 seconds and it won’t, but it will immediately on the second try. While this is no problem, I am curious if it is normal or a problem that I don’t know I have.

 

Have the fuel pressure and rest pressure checked.
The fuel pumps have a valve built into them. When you shut the car off the Valve closes. That allows the system to hold pressure for the next startup. Those valves go bad then the fuel drains back into the Tank.

Then whe you try to start you need to pump fuel from the Tank to the engine before it will start.

 

Yep, sounds just like mine. I usually turn the key all the way and let it sit there while I put on my seat belt and then crank it over. That gives the pump a little bit of time to prime. Time for a new fuel pump DAMMIT!!!

 

Try turning the key to the run position without attempting to start, turn it off again and then try to start. Maybe a fuel pump switch problem?

 

I've been having the same problem with my '98 XC.

Where would my fuel pressure regulator be located?

And, is it easy to replace or in to the shop it goes?

Thanks.

 

The fuel pressure regulator is mounted in the Fuel Rail.
Some have a vaccum line going to it some don't.
If it has a vaccum line remove the Vaccum hose and see if it has Gas in it. If it does then it is bad.

It is fairly easy to do. Pull the Fuel rail out of the intake. Then unscrew the Keeper plate and remove and replace.

 

Ok, thanks for reply.

 

Let me know what you find.

 

Does my 98 T5 have a fuel regulator or is it in the tank with the pump? Thanks in advance.

 

You have a fuel pressure regulator on the fuel rail.
The fuel pump also has a check Valve in it.

 

Update...

So, I acquired a fuel pressure regulator from a Volvo dealer.

My mechanic who is not a Volvo tech or a Volvo service person, but is no dummy, could not figure out how to install it.

He showed me the current regulator on my Volvo (looked bigger to me) and that he thought that they sent me the wrong regulator or that I needed to get the whole rail.

I called Volvo later re the part (#9146761), hoping maybe they sent me the wrong
one. Running through my VIN, they determined that what I have is what I need.

So, is there anything further I could tell my mechanic regarding the pressure
regulator or its installation?

Thanks.

 

Maybe it is an Updated one.
Any way you can post a picture of it?

To install as long as it looks close to what is on there. The Fuel rail will need to be removed then the Retainer strip will have to be removed with the Torxes screws then the regulator will pull out like the injectors do.

 

Ok, I just took a couple of photos of it. Am trying to figure out how to get it to you on this system.

Did the regulator fix it NorthernVolvo? Inquiring minds want to know. If I can fix the hard starting I might just keep mine, I've had it in the Auto Trader for two weeks and no calls yet.

 

I'm back.

So, after aquiring a fuel pressure regulator from the dealer and having no luck with my local mechanic re installing it, I decided to take the car and part to the dealer to see what they thought.

Typing off my invoice, they said... "Checked for DTC's. None. Checked parameters on monitor test. ECT sensor seems high. Ran fuel rest pressure test. Pressure gradually drops. Removed injector rail and found #2 injector leaking badly. #1 dripping a bit but #2 is excessive."

They did not have part.

Went back today a week later and #2 was replaced. The service guy who waited on me said to see if it gets worse, if so, come back and they would replace #1.

Service manager indicated to the service guy that both should have been replaced.

Me, not knowing what to do, left with plan to see how car started.

On starting, I notice no real difference.

Later, seeing that injector part was only about $25, I don't know why #1 was not replaced too.

 

Yes they should have replace #1 as well.

 

#1 has been replaced and vehicle now starts like a dream.

 

Congrats.

 

I am having same problem with my '00xc70. It takes a while to start it. I wanted to check and replace fuel pressure regulator. Or swap it with my '98v70 non turbo just to see if that is the problem. One seems bigger than the other but I think fitting is the same. None of them have vacuum lines coming out. After checking on eeuroparts.com, both cars require same fuel pressure regulator (same part number) but picture shows that they should have vacuum lines coming out. Is it possible to have more than one regulator??
