Hey everyone...
Finally got the 86 back on the road again and was driving beautifully however when I went to park it the other day, put the car into reverse...died ...and hasn't started since. Checked for fuel pressure at the rail and nothing. There is fuel flow and i hear my fuel pump going when I jumper the grey wire in the engine bay... but there is no pressure. I have an accufab FPR and it seems to be ok. I took it apart and looked at it and the diaphragm is fine. I even replaced it with a Bosch unit I had lying around which was not from a GN but some other car (Mercedes or BMW I think i recall but it fit exactly) and it seemed to not make a difference. Still no pressure. Replaced the fuel filter still same. So my thoughts now is to drop the tank and see if the fuel pump is somehow leaking back into the tank. Is this possible? Is there anything else I should check before doing that? I recall there being a walbro pump (not sure which one but it is about 10 yrs old) installed. I hear it whirring away In the tank but if the fuel pump to the gas line hose or whatever has some sort of breach I think this would be the result. The car is on the street parked so i will be doing it there. I used the pump as is to drain the tank into gas cans, but if i put my thumb over the connected tube I can stop the flow like nothing. No pressure. Fuel pump is hot wired also. Thoughts? Thx in advance...
