Cranks but No Start - ZR-1 Net Registry Forums

green zr 1 · 11-18-2006

In the last month, ZR-1 has started and on warmup when the idle comes down to 700 RPM, it stalls. Got sys on gauges, battery light, no ses light. Replaced battery, cleaned grounds to frame under the battery, Engine cranks fine, battery light still on, no ses light. GM service manual says I should have ses light. Do not hear fuel pumps and did not get spark on last attempt. Air conditioning comes on sporadically during cranking. It has started sporadically and run fine a couple of times with no symptoms during these problems. Any help is appreciated. Thanks, Shannon Walton 1990 ZR-1#1066
