Hi all
happy new years !!
just got a 2002 trailblazer 4.2 4 months ago
i was driving 2 days ago and the engine just turned off
all electrical works, the dashboard and all, but truck don't crank,
so i checked my fuses and fuse 28 ( PCM1 ) was blown
i replaced it, the truck cranked, turned on for a second and shuts down
PCM fuse blew again
I watched a video on youtube about some guy who says that most of the time is the fuel pump who shorts or the fuel pump cable
So i removed the fuel pump relay ( micro relay 41 ), replaced PCM1 fuse ( fuse 28 ) and the fuse don't blow
That leads me to think is the fuel pump,
is there any more tests i can do?
fuel pump is around 140 to 300
i do not want to buy one, replace and find out that is something else
Thanks
Rolo
