Premature Catch When Cranking on 190e

[moomoomeow]

Any time after my car has been sitting and i try to start it, the engine "catches" within second or two, but if i let go of the key the engine fails, or just barely is able to get started.

In the morning it ALWAYS starts immediately, but as i said, after the car has been sitting, when i go to start it, it will catch immediately and not actually be able to start. Second try always works fine.



How do i prevent my car from prematurely catching, or trying ot start before it is ready?


I ask, because i have remote start installed and since it runs based on a tach signal, it stops cranking the engine when it "catches."

Any help would be great. thanks.

No hints, but sympathy. My '87 300TE has done the exact same things since I bought it about 18 months ago :?

fuel pressure loss probably the accumulator/fuel filter/porous fuel lines/loose fittings

Agree with Tecky - my same problem was caused by a leaky check valve on one of my fuel pumps.
