Re: no vacumm on injector pump
A cheap fix would be to put a booster pump on there. Run it for a bit like that and hope that the vanes in the pump free up. It will mess up the internal pump pressure a bit though which will mess with your performance and gas mileage but it will run.
You only want about 3psi coming in so be sure to use a very small pump.
Look up "Autobest 12D Externally Mounted Universal Diesel Electric Fuel Pump" on amazon. It is $24.
Run it with that for a tank or two and then take it off and try running it without.
