I would guess after sitting 2 years. I will most likely need a fuel pump, fuel filter,possible pressure accumulator , unhook both fuel boths fuel lines together and runs the pumps. So that the fuel is getting returned back to the tank you may have to put a battery charger on low also.let run for an hour ..while doing than take all the injectors.out. and lines off the fuel distributor. Blow them blow out all injector lines and injectors some.B-12 will help run them Ito the lines and blow out again.as for the injectors just spray the top of them leaving some B-12 on the top when to blow the compressed air through them.both that a couple.of.times for.each injector. Don't reinstall.lines and injectors just yet. Now you can unbridge the.fuel pump relay and hook both the fuel lines back up..pm bridge the fuel pump again don't get over the fuel dist back away some and press down on the air flow plate a few times for couple of seconds. See what come out the. 4 holes they should flow about same soaked as the rest of them. If all good install the injector lines and injectors. If fuel didn't flow.the.same.rate you have a bad. Fuel dist. OK al.good.bridge the fuel pump push down on the air flow.plate till you here fuel or a hiss.unbridge relay install relay

And try starting it....if.I.was.doing all that I would.pull the tank and clean it
Good Luck!
