I'm having a little freak out as of yesterday morning when my '78 300 left me stranded for only like the second time in 6 years that i've had the car as my DD. I'm sure i could eventually trouble shoot the problem but i'm in a bit of a pinch for time this wknd. So, i;m sending out an SOS to all you diesel heads out there in hopes of getting some quick ideas.....Here's the deal.
starting yesterday morning, i couldn't get 'er started right. After trying a couple of things ( changed both fuel filters) i did eventually get it started and i drove about 100 miles with no problems. Then after i left it parked all day its hard to start again!! WTFunk?!
the new primary filter doesn't looks cucked up. i've got yet another one just in case.
I also replaced the rubber fuel lines on the inlet side from the hard line to the filter to the pump inlet.
vacuum siphoned from the hard line. Fuel flow is seemingly good.
Hand pump on the injection pump is not behaving normally. its not pumping. hard to move. back pressure.
That's the jist of whats happening.
Anybody? any Ideas??
