Here you can talk about the joy owning a Volvo 480 brings. Non-technical discussions take place here, like what is the difference between an ES and a S version.

Engine Electrics

Post by yorkievolvo » Thu Sep 05, 2019 12:04 pm

Been going around in circles checking topics on the forum, trying to put together a 'How To' detailing getting a non-starting car to start. No success!
Has anybody got info detailing the whereabouts of the various parts of the engine electrical systems?
Photographs / drawings ( / whatever) showing locations and names would be most helpful.
Also explanations of what the various components / bits do.
My car is a 1991 turbo auto with a B18FT-107 motor.
All info welcome.

Got lots!

But define non-start a little more.

Will it crank?
Can you hear the fuel pump?
Checked for a spark?

And it's got an auto box, so there's the possibility of a faulty P/N switch too (you can only start with the gear lever in park or neutral position)

The questions asked, and info provided, by jifflemon and Brinkie (thank you gentlemen) led to this:
Connected a spare spark plug to the distributor, put gear selector to N and turned key to 'Start'. Engine spun over but no spark.
Same actions with P selected - same results.
Smelled petrol so assume fuel feeding correctly (?).
Made a cup of tea and checked Mr. Haynes notes. Persuaded that a visit to the local Volvo expert was in order.
Busy tomorrow so will arrange for Tuesday.
To be continued.

but if the 'inhibitor' switch is faulty this could be the problem, not sure if it is on the box or on the gear lever?
find switch and 'jumper-it'
that would be my first port of call :wink:

lets start with some basics:

now when you tested for a spark, did you test from the king lead, or a spark plug end? either way....

Sorry, jifflemon, I didn't make it clear. It's a B18FT engine with Bosch EZ210K ignition.
The car's in the garage, has been started but ran for only a few seconds.
These bits have been requested:
full set of ignition leads (inc from coil to distributor),
ignition coil,
distributor cap,
flywheel sensor.
Going to post on 'Wanted'.
Thanks everybody.
