Probably? To be honest, I have no idea. It cranks quite quickly though, both when it starts right away and when it's trying to start but taking awhile.Original battery?
Lol. Yes, I believe the battery is completely capable of starting the car. It always cranks at the same speed, just sometimes longer than others. And I spoke too soon about the multiple attempts. I just went to get some dinner and it didn't start on the first try. It had been sitting since last evening. Then again, when I started it after four days of sitting, it started right up.It depends. If it's cranking at different speeds it's probably a symptom of the battery having different charge levels and the starter struggling more some days than other. If it's always cranking at the same pace (assuming it's as it should, not just barely turning over) but it'll crank for a longer period of time, a new battery is probably as helpful as checking the tire pressure. I'm not saying it's not the battery, but if you're going to start in that end I'd also make sure the exhaust is clear of bananas (just kidding)
Edit: when you say you pushed the button before starting it, did you press and hold or just press it? In the former case, it'll enter ignition mode II and in the latter mode I. If the pump was going to activate in either mode it would be in II of course but I have no clue if it actually does.
I don't have a VIDA/DICE yet, as this is my first foray into "modern" Volvos...and it's all pretty useless on a 121/1800/240/740/940. I leave for vacation tomorrow, so hopefully it doesn't get worse. Maybe I'll order a DICE unit while I'm gone.Edit: as always, checking for error codes with VIDA+DiCE or with a reader than can read volvos codes is if you ask me always starting at the right end.
I do mean the return valve, which as I understand it is part of the pump assembly (and as such is hundreds of dollars, vs. the what, $5 that I'm used to in a redblock).posaune: Off the top of my head, if the fuel pump is bad then the car would probably not work as it should under high load, e.g under a kickdown. I'd guess it's losing fuel pressure. Not sure if by check valve you mean return valve but in that case, I'd suspect something like that and thus it taking the car an extra second or two to build fuel pressure to get it started.
Sadly, I know that dropping the tank is necessary. P3s are the first that don't have the access hole under the rear seat. Of course.It also seems that removing the fuel pump requires dropping the fuel tank. Which is a "saddle" type as it's called, sitting on both sides of the prop shaft. So you'll need to drop the panels on both sides of the prop shaft, and then the prop shaft itself. And then the entire tank and remove the level sensor and all that. I'd pay for troubleshooting before anything else if you don't want to buy a dice yourself, rather than changing the pump on a hunch. which is insanity anyway.
My S80 sometimes does that. Seems to be rarer than on your car though. I remember in 18k miles I've owned the car that maybe 2 times it took a second try. Maybe 10 times it cranked for more than a second and started.Just another update, though I don't have much to add so I'm probably just talking to myself here.
I finally had a little time to do stuff at home, so I ordered a fuel pressure gauge and will report the findings. One thing that I find really strange though, is that if the car sits for a long time, sometimes it'll start right up. Wouldn't that sort of point away from the anti-drainback valve in the tank? Or does it prime itself if it's been sitting for a certain number of hours/days?
A summary of what it does:
Fairly regularly now, if left overnight, it'll require two tries to start, with a bit of a stumble when it finally does.
After that, during the day, it always starts normally.
Left for seven days, came back, it took three tries to start.
Drove it for a few days with the usual behavior- maybe more mornings with two or more tries.
Left for eight days, came back, and it started immediately and normally.
Mine always cranks quite quickly. It just takes a long time to start. It's almost always in the garage too, so angle isn't an issue in my case. If it did it as rarely s yours, I might not car, but I'm worried about premature starter wear at this rate. Of course it also is a bit sad to have your beautiful Volvo not start....My S80 sometimes does that. Seems to be rarer than on your car though. I remember in 18k miles I've owned the car that maybe 2 times it took a second try. Maybe 10 times it cranked for more than a second and started.
Also replaced the battery once, when the battery was shot it just didn't even try to start the first time, then I insisted and it finally cranked slowly but enough for it to start. I replaced the battery 30 minutes later - that was 2 months ago - and the second time I remeber it needed a second crank was with the new battery.
It's hard to say for sure, but it looks to me that if the passenger side is higher when parked, it cranks longer... I don't think it makes any sense but that's what I feel increases the chances of long cranking.
