Hi I have a CTS 2003 it dose have TCM problems but was still driving to work.came home parked and now won't start.tried intake clner to see if it would fire .? No fire ? Any body know what next..?Im disabled so abilities are limited.
if you have tcm problems why haven't you taken care of them? what kind of tcm problems? could they be related?
fuel pressure, injector pulse and spark. Need all three at the correct times to make an engine run. Even if fuel pressure is not there, some times external fuel will let you start bu other times it might not be enough.
do you have spark?
there are many things that can cause a modern engine not to start. Best bet would be to hook up a scanner and see what data you can get before you start changing parts. Check for crank and cam signal. Check coolant and intake air temp. Check security. Check fuel pump relay... and more.
