Make sure the fan clutch is plugged in firmly. The fan clutch shares a 5v reference signal with the throttle position sensor. That could be the cause. It's where I would start, anyway.
Replaced water pump, but now…..06 gmc envoy
Hey all, I’ve got a 2006 GMC Envoy and about 2 months ago my old lady was driving to work when the engine started overheating, and after pulling over and her coworker noticing coolant leaking out they added more which proceeded to just gush right back out essentially and they had to get it towed back to the house. I did some research and decided to replace the water pump since that’s right where I noticed the coolant had come out from. After that and adding coolant, I have not been able to get it to start (except once or twice the first few tries only for it to shut off a few moments later). I haven’t touched the Envoy since then, because I have no clue where to focus my efforts. Really want to get my baby running again, all ideas and suggestions would be greatly appreciated.

Thank you. I’m going to check that, but my buddy who actually works with vehicles told me last night he thinks it could just be that I tripped the anti theft since I did the whole replacement while still having the battery fully connected. Not sure, but going to check your idea and his and find out!Make sure the fan clutch is plugged in firmly. The fan clutch shares a 5v reference signal with the throttle position sensor.

Well --- your buddy is wrong ... but buddies are like that.......
NEVER disconnect the battery unless the car's on fire or the battery is being replaced - but there's a caveat with that too.
CAVEAT #1 --- If you ever have to disconnect the battery - you MUST use a KAM device to save the adaptive strategies in the computers - and there's lots of 'adaptives' that you should not want to mess with.
CAVEAT #2 - is closely related to CAVEAT #1 --- these 'adaptives' are usually manifested in the HVAC system getting hit with radical swings to the extremes of their travels (the HVAC motors and controllers that move things - secretly - under the dash and in places where you do not want to go) --- because they have by now, really aged-to a crisp their plastic parts that will not like to make those motions again.
There's nothing to fear in changing water pumps, transmissions, brakes, light bulbs - all those mundane things that do not require you to take their power away.
If you suspect they might get zortched and/or you cannot trust yourself with a wrench under the hood for fear that you'll cross the battery posts (kinda impossible on a sidepost battery in a plastic box) - but you can just pull the respective fuse(s) to the circuit upon which you chose to not create fireballs.
Raise the bridge - don't try to lower the water.

PS --- if the Anti-Theft system is armed - the light on the dash will be ON or blinking --- I forget which since it was a while ago that I tripped one.
But all will not be lost as there's a simple - if not somewhat time-consuming process to UNarm it again that does not require a scanner - but if you are trying to steal the car --- as a thief, you have to stick around for at least half an hour to do so.
Yup - that was GM's answer to anti-theft devices from the factory - this on a vehicle that doesn't have a locking steering wheel!
