First thing you need to do is get a set of the VOLVO service manuals on the Diesel engine. The books are GREAT !! There are four books you need to get.

1) TP30789/1 => Design and Function => Engine D24T Turbo Diesel 2) TP30571/1 =. Fault Tracing Repairs D24T 3) TP30571/1S => Fault Tracing Repairs Supplement => D24T 740/760 1983-1986 4) Tp31134/1 => Reconditioning Engine

These numbers are for the Turbo Diesel but Volvo has similair books for the ALL the engines and sub groups of the car.

The fuel solenoid is located on the front-top of the fuel pump just above the cluster of injection lines. When the ingition key is tunred to the RUN and/or START positions the solenoid is energized (12volts) to open the solenoid and allow fuel to flow to the pump plunger and thus to the nozzles. Check to see if you you have voltage at the solenoid when in the run position, then hold the solenoid while an assistant turns the key from the OFF position to the RUN position and you should feel the solenoid click open and shut.

Try loosening one or two of the injector lines at the cylinder head and crank the engine. You should get fuel at the cracked/loosened injection lines. If you get fuel the problem could be with the glow plug circuit not heating to assist during a cold start.

The shut off solenoid is located on the injection pump and weather open or closed would have no effect on the fuel getting to the filter.The injection pump on the engine does all of the work,there is no in tank pump.If fuel is not getting to the filter housing,you have either a restriction in the line or an air leak between the pump and the tank.My money would be on the latter of the choices.The other alternative is that the pump is not pulling the fuel up.If that is the case you are in for an expensive rebuild.

Needless to say that is exactly the advice I would have given. The situation can be further diagnosed by connecting an auxillary fuel supply to the filter inlet, (a coffee can with a piece of tubing soldered in the bottom) and raising it above the injector pump so the fuel can run in by gravity. This will show you if the pump or filter is leaking. If not look back toward the tank.

Good luck, let us know what happens.
