1999 V70 XC AWD - Won't start / intermittent start.

Post by bbotzer »

Seeking some expert advice on this one…

We have a 1999 V70 XC that doesn’t get driven all that much, but last October (2018) when I was preparing to take it for inspection, I drove it about 5 miles, and when I got home, it wouldn’t start again.

So, I just let it sit in the driveway, all winter long.

1) I tried starting it several weeks ago, and it still wouldn’t start. It ‘cranks’ sufficiently, but no sign of ignition or even a
‘sputter’

2) After doing some investigations into what the cause might be..
a. I checked the schrader valve on the injector rail and it appeared to have good pressure.
(It was a ‘forceful’ squirt).

b. I removed and re-seated (not replaced) the Fuel Pump relay (I actually did that
with ALL of the relay’s I could find in that compartment).


3) IT STARTED ! - So, I drove it around for a bit, but when I came home…
It wouldn’t start again.

4) I then tried ‘exercising’ the shifter for the automatic transmission by vigorously moving it back and forth.
(Something I saw on a Video about similar Volvo’s not starting. )

5) Now, it seems to start normally .. So (maybe) problem solved ?

What I am wondering about is what the actual / fundamental cause of the issue could be ( of have been).

I plan to do some routine’ maintenance, like change the fuel filter ( which probably hasn’t been changed in a decade), We are considering selling the car, but I would like to understand what the root cause of the issue may have been so I can make appropriate corrective actions.

(Like, spraying some ‘contact cleaner’ in he the ‘shifter lever’ or whatever ‘actuator’ it moves
- if that is the correct thing to do.)

Was thinking of replacing the Fuel Pump relay also.

Does anyone know why ‘exercising’ the shifter would have that effect?
Is that a known issue with V70’s ?


All advice and suggestions appreciated. 😊

Could be a simple as oxidation build up on a switch contact from not being used.

Just driving the thing can knock some of the bugs out. Start using the car for non-critical trips, see if some of the bugs leave home.

Things can deteriorate from not being used. That is why people that know laugh when somebody says it ran when we parked it. That was then, this is now.

Hy,

Newbie on the phone

It looks like something I met with my first volvo.

Check the fuel filter could also be a nice idea, the ignition, distributor cap...

May be the issue comes from this part ?
