Intermittent Start Issue, Fuel Pump? 93 300CE
Hi,
I have intermittent starting issues due to lack of fuel to engine. Sometimes the engine fires up in 1 second, others it takes up to 30 secs with foot on gas pedal. Ive been researching fuel pump issues in the forums for a couple hours this morning.I will list some symptoms: When cranking for longer periods (up to 30 secs) it cranks for a while then starts to caugh faster and faster till runs the caughing last sometimes 15 secs until it will start. With key in on position no fuel pump noise ( I have read that this specific pump system does not prime in on position, only comes on when cranking/running. Please verify) When jumpering K38 pins 30 and 87, the pump aubible whirrs, sounds strong. New OVP Rebuilt ETA Thanks! James |
