Intermitent no hot start 850

The 850 has a "Fuel System Relay" item 2/32 in the wiring diagram
It enables The Plus side of the injectors. It is the same as the notorious RSR
relay, when it quits you might have fuel at the rail but so what if the injectors
cant run. I suppose the relay could get weird before it dies completely.

This relay is mounted above the radiator towards the battery side.

Google for "Volvo 850 Wiring Diagram", they're out there by model year, over 200 pages. The troubleshooters best friend. It has the schematics and component locations etc., and that's the same as the old Green books for 740's etc.
If you can't find it post back.

Bill
