1.6NA can't get pump to prime
« on: February 06, 2011, 03:41:13 pm »
My injection pump was leaking in my 79 Rabbit 1.6 at where the governor cover meets at the main pump. I took the cover off and replaced the gasket and put it back together. I can't get any fuel to come out of the pump. Not from the injector lines or from the pump itself. I checked all my hoses for cracks and what not. I changed out the fuel stop valve and nothing seems to work even after a dead battery worth of cranking.   

Please Help....... :'(

Make sure it ain't suckin' air and also make sure it has 12v to the solenoid.

'82 Rabbit, I put on a euro vnt-15, 2.25" DP, 2.5" exhaust, the result.....it whistled.

I removed the turbo, made a toilet bowl 2.5" DP, the result....it was deafening. Now it has a homemade muffler up front and a thrush in the rear, the result.....less loud.

Yeah it has 12volts and you can hear a click when you turn the key.

Where/How would I look for air leaks?

Did you use a vacuum device (MightyVac etc..) to prime/fill the pump with fuel ?

Or did you fill the pump with fuel through an inlet/outlet bolt ?

IF the pump is full of fuel - or even Half Full - it should produce fuel out of the delivery valves (where injector hardlines bolt to pump) while cranking car.

In other regards, you may have dislocated the throttle shaft alignment when you re-assembled everything.

According to B_Y_M - it makes no matter whether you put the throttle to wide open or let it sit at idle while cranking the engine. At that point, the throttle/fueling operation is working off a self-governor. If you have that misaligned, it could be your problem.

Just putting it out there.
