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.

I have 76 2.0 that I start every week or two. Turn the key on then depress the gas pedal two times holding it to the floor while cranking. Mine starts within 1-2 seconds. (IMG:style_emoticons/default/beerchug.gif)

Also, unless the engine is brought up to operating temp ( driven ) for 15 or 20 minutes, weekly starting / run for 5 min is doing more harm than good. Oil becomes contaminated with fuel from cold starts / moisture builds in the oil and exhaust system. ( Water is a by product of fuel combustion ) |
