Did a panic stop first of month in my 93 Vette, it sputtered and died, wouldn't restart. Towed home, coil was dead, replaced and now starts immediately and then dies. Injectors pulse only when accelerator is being pushed down, hold it steady, it dies, let up , it dies, keep pumping it, it stays running, revving and noid light flashes every time peddle goes down???? What is linked to accelerator movement to trigger pulses??
