Lexus Troubleshooting Questions? Ask a Lexus Expert
Hello my name is***** am an ASE master tech, and can gladly help you with this.
You need a scan tool to check for codes.
If you ruled out fuel, are you getting spark? are you getting injector pulse? do you have good compression?
If it turns over it is not a security issue.
If do not have spark, you could have an ecm, fuse or harness issue.
To check injector pulse. You can make a noid light out of a 194 license plate bulb, bend the tabs out and stick it into the connector of a fuel injector, have someone crank the engine and watch the bulb flash.
Compression check is done with a compression gauge. You remove all spark plugs and check each cylinder while cranking the engine. Do this last, as it is the most labor intensive. Check for spark and injector pulse first.
