I recently replaced the fuel pumps in my Cabby and I'm having trouble getting it started now. I figured it would take a bit since there's no gas in the lines but it just won't start for me.
One of the lines to the fuel accumulator was disconnected (not by me) and a friend of my mom's said to take it off again while trying to start the car. I don't see how it will help because then air will just stay in that line anyway but I know I don't know everything so I wanted to get others opinions on the situation.
I'd try his idea just for the sake of trying it but I won't be home until late tonight anyway.
Yours is an 89 cabriolet ? Im no expert but is there anyway you could've swapped the fuel feed line with the return line on the in-tank pump ? When you turn your key on can you hear the pumps running ?
Try un-hooking the line from the in-tank pump where it feeds the outer unit and turn your key on to see if fuel is reaching that point, if it is then un-hook the line coming out of the outer pump and see what you have there ? Did you get a new pump or used ? Cis and Cis E runs on higher fuel pressure than newer Digifant systems. Do you have part#s from new pumps ?
and the other with a Bosch pump. Both new.
I had tried starting it a few days ago (but had forgotten a washer so it was leaking) and fuel did reach the main pump since that's where I saw it leaking from. But maybe it was fuel that was already in the lines, not new gas being picked up? So I'll try what you suggested tomorrow.
