Car Forum / Volvo Cars / August 20061991 240 DL Loose Wire in engine compartment
I have a loose wire - It is mounted/screwed to the firewall on the rear of the engine. By itself. It is a flat wire that is sort of cloth/mesh looking about 10-12" long and goes to nothing. The loose end is fraid and looks like its some kind of ground wire, Anybody have a clue what this is? Also how do I know if the Fuel Pressure Regulator is bad? > I have a loose wire - It is mounted/screwed to the firewall on the rear > of the engine. By itself.

It's a ground wire to ensure engine has negative ground. >> I have a loose wire - It is mounted/screwed to the firewall on the rear >> of the engine. By itself.

There should be a crimp-on eyelet for the loose end held onto the engine by one of the cam cover bolts. If you don't have one, get a good book about your volvo which will have diagrams for this stuff, as well as trouble shooting procedures. Even a mediocre one like the Haynes manual would help, but the Bentley manual is better. As I've posted before, the BEST wiring schematic I have come across is in the Mitchell Repair Manuals in the public library. > I have a loose wire - It is mounted/screwed to the firewall on the rear > of the engine.

The FPR is bad when fuel runs out of the vacuum hose going to the intake manifold. At that point the diapragm inside the capsule is ruptured and raw fuel is gushing into the intake manifold in a large enough quantity to flood and hydrolock the motor. Bob SignatureThe goal when driving is to miss the maximum number of objects. Its a ground wire on my 740 which has two , it went as well so I just replaced it after all we dont want power using our cables to earth do we? >> I have a loose wire - It is mounted/screwed to the firewall on the rear >> of the engine.
