Starting - Troubleshooting Long Cranking Times: Overview

90bmw18 Group 13 Fuel System
Bulletin Number 13 08 90 (3096)
Woodcliff Lake, NJ October 1990 Service Engineering
SUBJECT: Long Cranking Times

MODELS: All

Situation: The starting characteristics, and therefore the starting time, of an engine depend on several factors. All the "basics" should be checked first before any further troubleshooting is conducted.

This Service Information Bulletin outlines basic troubleshooting hints as well as a procedure for checking the leakage rate of an electronic fuel injector. Only leaking fuel injectors should be replaced and will be covered under warranty.

We now have to make every effort to effectively troubleshoot any "long cranking" complaint and perform the necessary repairs while reducing non-defective component replacements.
