2000 ZR2 Blazer Hard Start and High Temp Input Code
I have a 2000 ZR2 Chevy Blazer with 120,000 miles on it. I recently changed one of the injectors on it because i had a misfire. Changing it stopped the mifire but created another problem that is just as troublesome. I've checked the wires coming off of the Coolant Temp Sensor and they all seem fine. Since changin the injector its been a hard starter and the SES light stays on none stop. I'm wondering if anyone can help me with this problem.
Pleas Help.

well than, if the gauge doesn't move than the pcm thinks that the outside air if cold so its adding alot of fuel.. which temp sensor did you replace? was it the one next to the egr or the one on the side of the cylinder head?.. and better yet, did you plug in the temp sensor on side of the driver's side head? did the wires maybe melt on the exhaust? let me know.

Found out that the wires were covered in coolant so the wires were shorting out making the pcm think it was too hot. Got the wires cleaned off and replaced and now it works like new
thanks for the help
