No start problem. Car cranks but won't start. Will catch if sprayed with starter fluid. Checked fuel injector signal with Noid light, and NOTHING.

ECM Problems? Ground missing? What do you all think?

First, it helps to state the year of the vette, and fill out your profile. On a l98 the signal is picked up from the pickup coil..sent to the ECM and from there the signal is sent to fire the injectors...there are also injector fuses in the fuse panel.

Sorry, '90 L98, auto, bone stock.

Fuses. Didn't think of that one. I'll have to check that out.

If both fuses are good and the distributor is providing reference pulses to the ECM, then the ECM is suspect.

Pardon my ignorance...

How do I check the reference pulses from the distributor to the ECM?

Can I check it with a light?

Thanks!
