Hi everyone, my 2006 Hummer H3 started fine in August, but the metal fuel pipe under the car leaked due to rust. I replaced the rubber pipe. In June, when I turned the key, there was a crankshaft and fuel pump, but it would not start. I tried the On position for 10 minutes, off for 5 seconds, repeated three times, but it still had passlock. I once replaced a Colorado pcm bcm assembly with the same engine as this car, but it still would not start. I cleaned all the ground wires in the fuse box and engine compartment, but it still would not start. In October, when I turned the key to start, the car made a relay pull-in sound, and then suddenly lost power. It felt like something was shorted out. The vehicle was completely out of power as if it was dead. I had to remove the battery cable and wait for a while before the light came back on. It felt like an overcurrent protection circuit. Does anyone have any suggestions that can help me? I am currently in Toronto.
Passlock light sometimes flash.sometimes keep light.

 

Welcome to HF.

MOVED from the FAQ Section where it tells everyone NOT TO POST ANYTHING just because you thought up some question.

Can we assume your Battery is fully charges and has 12.6V at rest? Can we assume you replaced the crappy azzed OEM Battery Terminal Connectors with a quality aftermarket set like Stingers or your favorite brand?

Did you take apart the fuse block from the fuse box tray disconnecting the main harnesses and not put it back correctly?

 

I'm sadly at a complete loss. I do not understand your post. A focused explanation of vehicle history would be wise in getting possible assistance.
