spider graduate fuel injection problem

[slab]

i am a new alfa owner. my '85 spider would not start. cold start injectors would work, engine would start for a second then die. regular injectors would not kick in. sent bosch computer off for work. get it back and now no fire to any injectors. sent it back and they say it's ok. please help.

Are you getting spark? L-Jet won't fire the injectors without a tach signal. Check the connection to the inductive pickup on the flywheel sensor.
