2000 Impala cranks but won't start
Replace module not getting spark cranks won't start
Make sure battery has a full charge and connections all good? Did you check voltage and ground for ignition module, before replacing the module? In the diagram, the top wire on right side, pink wire, that is voltage, fuse protected and goes hot with key on. The bottom wire on the right, black wire is ground. You can take connector loose, use both ends of test lite between the terminals for those two wire colors, turn on key, if the lamp comes on you have good enough voltage and ground, for the lamp. The crank sensor is important, I'm not saying replace anything, but, you can do some testing. How long since a tune-up? Any applicable trouble codes?
