Hello,
If you have checked all the wiring at the contact trigger points(look very carefully, it is common to see a single wire strand just barely holding onto one of the metal connectors at the end of the wire) and at the injectors, you may have a damaged contact trigger points set.
The points on this set only send a ground signal, so the contact side usually just needs a wipe with a clean match book cover.
But the rubbing blocks on each point set needs to be lubed during each tuneup and this is often neglected and this leads to wear to the extent that the point set might not open and each point set runs a pair of injectors.
What vacuum sensor do you need?
1970 Volvos came with an "010"(last 3 digits of the Bosch part number), the 1971 Volvos came with a "015", the 1972 and 1973 Volvos with a B20E got a "015", with a B20F and a manual transmission the sensor is a "035 and with a B20F and an automatic transmission used a "054".
The information above applies to 4 cylinder Volvos.
Did you know that the current list price for the one vacuum sensor is almost $3000.00 from Volvo?
I strongly suggest that you have yours rebuilt by Fuel Injection Corp as they charge at lot less than $2800.00 and when I spoke to the owner, he knew about some of the internal workings of this unit and claimed he could fix them.
