Default The problem with Prv's

Had to make another thread for this one as I'm ruining my original one with all the other vvos I pickup while building my 242 turbo.


Picked up this non running 1981 262c a few months back and started in on trying to resurrect it!

So far it's one step forward ten steps back !

I've replaced the main fuel pump, tank is clean, tank pump working, new fuel filter, fuel injectors are clean, fuel distribution unit seems to be working (depressing the air metering plate it springs back immediately,indicating the valve is moving freely).

Fresh plugs too!

She's running on starting fluid so I think the timing is ok.

Put some 108 octane into it last night with some premium and nowweve lost spark, think I've lost the ignition control unit now any pointers?

The ignition is the bosch breakerless type similar to what is used in the B21F, and FT. The signal generating coil in the distributor likes to fail and can become intermittent failing when hot. You can ohm it out. I forget the specs but it's in books like the Haynes. Check it for the Volvo wire decay. The connector between the distributor and the ignition module can fail where the wiring enters the connector.

If you don't have spark it won't trigger the fuel pump relay with the coil signal. So, no fuel unless spark is working.

Thanks man I still have some bits leftover from my b21ft so hoping the breaker less pickup bit is the same. I doubt it mind the distributor in the V6 looks massive !

At least you have focused on the fuel system. The K-jet system does not appreciate storage and especially the fuel contamination that goes along with gas sitting for years.

The standard first place to start on the fuel side is the fuel pressure test since everything operates mechanically based on fuel pressure. Easy to say, a little harder to do. Start here: https://www.turbobricks.com/forums/s...d.php?t=289775

Most of what I learned in working through my Bertone that was stored 19 years in a hay barn. I ended up replacing everything from and including the gas cap and injectors.

Good chance that the O2 sensor is dead. New, it was a 25k mile maintenance item.
