- |
- | _Bosch Fuel Injection & Engine Management_,
- | Charles O. Probst, SAE
- | Robert Bentley, Publishers
- | ISBN 0-8376-0300-5

- | more.
-
- Thanks - I'll try to unearth a copy. I received, and replied to, email
- from someone who offered to scan and mail me a schematic if he had one,
- but no further response yet .... (Waiting hopefully, John!)

- | Did I read this right? Surely then it is a sensor/injector electrical
- | fault.......
-
- It's more subtle than that. This unit runs OK in a test rig I made up
- (a function generator to simulate the ignition pulses and three pots to
- simulate the air sensor and thermistors), producing identical injector
- timing to good unit. Put it in a vehicle (*any* vehicle) and the
- engine will fire but not run. It's probably something simple (most of
- the thing is evidently working correctly), but without a schematic to
- work with, I haven't made much progress.
