'89 740 GL Cold Start Problem 700

posted by  someone claiming to be swede4 on  Fri Feb 27 15:42 CST 2004 [RELATED]

There is a checkvalve at the outlet from the main fuelpump. If the spring in the valve breaks(just did it on my 740 2nd time in 5 yrs) there is no residual fuelpressure in the injector lines and it takes quite a bit of cranking to get the engine started. Easily checked with a fuelpressure gauge.
