2002 montana fails to start after warmed-up. will have to sit 2 hours before it will.
02 Montana starts great cold and runs good. turn it off for 5 minutes and it won't start for 2 hours. fuel press. good, good spark, turns over quickly. it appears to loose injector pulse. replaced the ecm per dealer diagnostic and does the same thing. will run forever if you never turn it off. help..thanks
Just had a similar issue with my 2006. Very simple fix was to grab some throttle body cleaner and spray and wipe down the throttle body. Just did mine last night and took about 15 minutes. Runs like a champ now.
