How does the fuel pump work? 300D won't prime.
Hey there, I've looked at the archives, but I'm still stumped. My car acted like the fuel filters were clogging, I changed them, it started fine, ran for about 2 minutes and crapped out. Started again and made it down the street. Died and needed a tow back up the block to my driveway.
When I try to prime the air bubble out of the lines (I can see the air bubble in the clear line immediately downstream from the primer pump) the primer just moves the bubble back and forth a little bit. I thought I'd replace that clear line. I also wonder if the fuel pump can fail in such a way as to prevent priming. How does the fuel pump/primer assembly actually work? I've got a spare fuel pump on my spare motor.
Oh, also, I checked the primer pump, it's of the new style and seems to function properly. I just don't know where it's pressure is going to... not into the secondary filter, that much is clear. Also, with the secondary filter unscrewed a little, the primer still won't push fuel through the line. I blew the fuel back up the line, made the primary filter clean, then used the primer would re-prime it... just a data point.
Thanks for reading!
Cheers,
Ash
