I didn't touch anything under the hood before it happened. I took the air cleaner off and made sure the chokes were off when it was doing that. Could the pump short it self, raise the fuel pressure, bypass the needle valves and raise the idle? There is no fuel pressure regulator. The ammeter discharges when the idle goes up so I think its fuel pump related.




If the fuel press went to high it would just cause gas to drip from the nozzle's and flood the eng as it would run bad and be hard to keep running. It would not cause the idle to raise. It sounds like it stops charging and takes that small load from the alt away and can cause the idle to raise some as you said it stops charging. I would actually check the charging sysem and make sure the body ground is good as maybe the body ground is bad and it was finding a ground thru the fuel pump ground ?? Ron
