I bought this car about a year and a half ago from my highschool/college auto teacher Mr. D for $100 He said it needed a new head and to be rebuilt. I rebuilt the engine completely, New Gaskets,bearings,oil pump, pistons,rings,waterpump. Just about everything except the crank and block are new or replaced. It has a rebuilt head.
I got the engine back in and mostly hooked back up besides some water lines. I had to pull the fuel tank out due to it being completly full of rust. I wanted to hear the engine run so i tried to use a fuel jug and siphoning the fuel to the injection pump. I thought i had a bad pump because it was only putting fuel out barely on two cyls. I got a different injection pump and cant even get it to do that. I think i wasted my money getting the 2nd pump cause i think both the pumps are good the fuel is just losing suction from the fuel can. So i ask do i have to have the fuel tank in to get enough pressure to get it to the pump. I need to clean the tank i think the only way to do it good enough would be to cut the tank open or is there a good way to use a fuel cell or different tank.
i've run my '82 rabbit diesel from a jerry can before. doesn't need to be from the tank. you might have air in two of the lines... try cracking each injector union until you see fuel seeping out, then close them. do them one at a time. make sure the hard lines arent clogged and i didn't read if you used new injectors but it could be fouled injectors.
On the second pump the stop solenoid may also be bad. I like to remove the "out" bolt and fill the pump that way and then run it from a can.
As itchy said, crack open the lines at the injectors until you get fuel out of them.
I had a pump that was sitting for years so when I installed it I didn't hook up the hard lines at all. I cranked it for quite some time before all 4 ports were squirting fuel. If you do that don't touch the ports at all while they are spraying, the fuel will inject right into your finger and you may end up like me. :lol:
I've had the same issue. There are a few ways around it.
First, without buying anything, take and cover the opening of the fuel bottle with a rag to create a partial seal, while craking, blow compressed air into the fuel bottle to basically pressurize the bottle and force the fuel into the pump.
Second, you can get one of those in-line boat primer bulbs and run that on the line going into the pump. From what I've heard, you're basically guaranteed a good prime every time.
