Could a vacuum leak or poor ground be a starting killer?, 73 914 2.0 - EARLY Sept 72 VIN4732901102 Options

I am having a world of hurt. Car ran on Saturday. Drove it an hour. Got slightly warm and it ran rich the whole time. Crack in the dual tube elbow into the Manifold corrected last night.

Gapped at .017 to start. Waiting for dwell/vacuum/fp gauge/timing light in mail.

Backfires and will not start. I have the ecu at 11, all electrical checks out, changed ht sensor and manifold sensor last night.

Have one chinese relay but the rest are wehrle and good

chinese one ran the fan so it seems OK All hoses new. Fuel hoses too. How serious is a poorly adjusted fps on the drivers side? I am sure mine is not on 29psig.

I am wearing out my solenoid and maybe my ignition switch!

Thanks!

John

Thanks Root Werks and RealRed!

I meant the Manifold Pressure Sensor, and later I was talking about stupidly messing with the Fuel Pressure Regulator. Dope that I was, I have to wait for my fuel pressure meter to arrive and undo my work from Saturday.

Replacing the dual elbows into the MPS may have worked, but the backfire last night was so loud I have to wait till this afternoon to try again.

Root Werks - The green wire seems intact. Rechecking the gap to .17 later today.

Checked all hoses, cut some for tighter fits, but I think I may have a bad trigger.

It sends out some spurious signals when testing with a continuity tester when cranking, but the damn thing ran rich but pretty well on Saturday before I messed with it.

Truly, as it warmed up in SoCal, it starting messing up.

THANKS!

John
