Hi,
I recently swapped my chassis wiring harness on my 350zHR because the old one was having issues due to a security system that the previous owner wired in. Before the swap, the car started right up and drove fine every time. Now that I have swapped the harness (with a new one that I know was perfectly fine before the swap) it will crank but not start. The way it cranks, it sounds like it could be a ground or a connection that s messed up I think. The grounds that I'm aware of are the two in the interior behind the dash, the two large ones in the engine bay, and the one small one near the battery also in the engine bay. My only concern is that when I was pulling the wiring harness under the heater core hoses, I had to pull relatively hard. I don't think anything would be damaged, but the car also won't start.

The things I've double checked so far:

• the grounds that I listed above
• The connection of the gas pedal plug
• the connection of the ecu plug
• the interior fuse box connections
• all fuses in all three fuse boxes
• the connection of the ignition plug

If anyone has any ideas or can help at all that would be great. Thank you!
