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.

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. 10 seconds of cranking or turn the key wait 10 seconds and then crank? Key on without cranking the pump should only run for roughly a second or two. If you are talking about 10 seconds of cranking try cycling the key on/off a few times before you attempt to crank. If after cycling a few times the car start immediately upon cranking than it is most likely due to you not holding pressure in the fuel rail properly. If it still takes a bit of cranking to start you have other issues to address. A properly working d-jet car should start on the first crank without touching the pedal. I had my 1.7 in Colorado last week and was doing exactly that, didnt even need to be in the car to start it. |
