Re: Fuel Pump Not Running
This from 1995 Volvo 850 Review: cartestdrive.com
Standard on the Turbo and a $500 option for the base level 850 and 850 GLT, the side bags join dual front airbags, Volvo’s SIPS (Side Impact Protection System) and new Daytime Running Lights as the most comprehensive passive safety package yet available from any carmaker.
At the top of the line, the Turbo package adds the side-impact airbags, split leather upholstery and electronic climate control.
If you go to Parts Geek search 1995 Fue/Inertial Shut-Off Valve and has for my 850 turbo yrs '92-'96.

Re: Fuel Pump Not Running
Excellent
Now work your way from the relay and check if the 12V isnt getting to the pump because
either
1 The fuel pump relay isnt getting a 12V feed - check upstream for 12V fault
B The fuel pump relay isnt getting triggered to close, or isnt closing.

Re: Fuel Pump Not Running
Waiting to receive a checked out used Main Fuel Relay from Mayflower Volvo. She supposed to call back. This will have the connector attached w long enough wies that I can slice it in for good connection at the relay. My connector is gone and broke a brittle wire. So need get and do this before go any farther.
Going to clean MAF Sensor and EGR Valve w carb cleaner tomorrow. Might as well. Cheap fix. Trying to knock out any and all suggested problems while car is down.
After all this if not start I'll start into Timing Belt...UUHHGG!!

Re: Fuel Pump Not Running
Checked on a kit for Fuel Pressure...$120...Nope! Have pressure at back by tank and at injectors where release valves are. Doubt this the problem.

Re: Fuel Pump Not Running
Don't use carb cleaner on the MAF!!! It will likely ruin the sensor, and be an expensive non-fix.turboman850 wrote: ↑Wed Oct 30, 2019 4:01 pm... Going to clean MAF Sensor and EGR Valve w carb cleaner tomorrow. Might as well. Cheap fix. ...
I post this over and over again on here: there is no point in cleaning the MAF unless (1) it is visibly dirty or (2) you have tested it and it is known to be bad. Otherwise, 99% of the time, cleaning the MAF does nothing more than sell MAF cleaner.

Did you find no 12 V supply at the fuel pump relay?
Don’t skip steps!

Re: Fuel Pump Not Running
Ok...now still no pump start. Checking voltages Everywhere!! Well...No readings on pin 86 of FPR to the actuator side for pull down switch side and start fuel pump. Put 12v at Main Fuel Relay w jump in FPR...pump runs fine.
Now checking cont. mod for signal/voltage to the pin 86 from pin 27 of Cont. Mod. there is No Pin in 27 and counted out like 5x. This send volts to close switch to pump. Ooww!! Schematic I been using pins not correlate to print!! And no where in the pins give "ohm" reading to pin 86 of FPR!!! So now in a search of "correct" print and schematic of Cont. Module. You got any help out t fellow Volvo there '95 Volvo 850 Turbo Sportwagon????

Re: Fuel Pump Not Running
Watch your acronyms. FPR is commonly used for fuel pressure regulator , which doesn’t have electrical connections.
Using the wrong electrical diagram is frustrating indeed. It’s even worse when you find out you have the right one, but it has mistakes, got that T-shirt courtesy of VWOA.
I think right now
Your pump runs with 12V at the main relay and the fuel pump relay jumped...conclusion, fuel pump and wiring from main relay to pump is good.
You aren’t getting 12V to the main relay.

Re: Fuel Pump Not Running
+1 - check all wiring (power AND ground) to and from the main fuel system relay. Ditch the wiring diagram if its giving you that much trouble and manually trace each wire using a continuity test. Check all the connections, especially any pins inside the connectors. You can back probe both sides of a two part connection to make sure the pins inside are making contact. Be sure to use a small piece of wire (or a paperclip) so that you don't disturb the connector.
