I installed a Fleece grid heater delete. Everything went fine, or so I thought. The engine turns over, but won’t crank. I’ve double checked all sensors and everything is plugged in. When it tries to crank fuel is spilling from the overflow valve so I should have gods pressure. Seems like maybe the injectors aren’t firing. Any ideas would be much appreciated!!

Never installed a grid heater delete, didn't figure I'd need one because it's just not as big of an issue as it appears on the forums.

That said, if the engine is turning over it's cranking. Do you mean it won't start? Do you have any trouble codes?

I saw a utube video, that stated there was a current load expected at the engines cpu, that was looking at the load the grid heater presented. And the guy on the video had to use a cheater resistance/ voltage divider on that lead into the cpu to fool it into thinking that the grid heater was still there.
