Just wondering. I have Bosch FI at Colorado altitude. My car will not start up right away unless I turn the key and wait about 10 seconds for the fuel pump to prime. All plugs and wires new, new fuel pump, and fuel filter. Moroso electronic conversion. New battery. I try to drive the car once a week. Just looking for advice. Car is a 1976 2.0 with 1973 2.0 engine. OEM fuel injection.

Right in the middle of the picture is the check valve (and overpressure bleed off). BUT there are a couple of o-rings on that little guy and they can get sticky over time, so it's not uncommon for them to not be working correctly. And these may not be appropriately addressed in the rebuilds. |
