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
