with my 2.0 d-jet i would turn the key on and off a few times befor i would crank it, and it started right up... cold or hot. It also had the fuel pump hooked directly to the postive on the coil.
Now with the 1.8, when i turn the key on and off a few times i hear nothing. Then when i turn to crank it, i hear the fuel pump running, but it cvranks and cranks and then starts. This morning i thought i was killing my starter and battery. I dont want to fry the ignition switch. what do you think might be the problem, i am almost willing to hook up my fuel pump incorrectly to see if it starts right up like it used to. The starter is less than a year old, and the condition of the ljet, needs refreshing. car runs with a little hesitation, i think from the throttle switch is worn. (bucking) and i have no power in 5th gear at all. i hear a very low hollw sound when i push the gas down at this speed. When i ease up on the pedal sometimes i can pick up a little speed. (is that lack of fuel?) plenty of power in 4th gear. cheers |

Here's my take on Bosch pumps. The inline pumps provide both high pressure and high volume so that pressure can be maintained at the injectors with excess fuel being bled off to the return line. For each type of fuel injectiion system, it's the pressure relief valve that controlls the fuel pressure and the pump merely has to provide enough volume to meet that pressure during use.
This pressure control system has advantages. The pumps are overdesigned and as the pump wears and output declines, it still works as long as the pressure releif valve can maintian pressure. So, since the engine sizes ( and fuel needs and fuel pressures) are about the same, a Djet or L-jet pump shouldn't make a difference unless it's failing That being said, do you have the L-jet or D-jet ( with knob) pressure relief valve??? Measure the FI operating pressure yet?? Ken |
