Fuel Problems 93 850? 5 cyl

Jun 27, 2008 3 Replies

My nephew has this vehicle which is stuck at the farm 2 hrs away. I will go there this weekend and repair it, but I am not familiar with Volvos.



He said it would stop-go-stop just like it was out of gas, but there was lots of gas in the tank.



Can someone tell me please:


-where is the fuel filter located?


-is it a mechanical pump or electric one?


-if electric, where is it?



Are there any special tricks or suggestions to troubleshooting and repairing/replacing these components? He says he bought a new filter and pump to take with us.



Thanks, Tom

Thanks for the info, Jarkka.

Turns out fuel system seems okay - I have pressure on rail !

But no sparks ???

So I pulled the coil assembly, with the power transistor mounted.

How can I test that to see if it's good?

Are these usually available at a scrap yard?

Is replacing this the likely solution, or am I going to find out it is a mysterious fault involving sensors and a computer, hahahaha?

=============================

Are you getting any trouble codes on sockets A2 or A6?
