Hey guys, I havent done much on my Nissan for a while and I just made my way over to this site (3rd sites a charm right?) Anyway... The Nissan is getting traded today, Sad day I know, Anyways, the harness was undone from the motor cause I was going to take the cab off, I plugged everything back up and it wont start, There is no dash etc in it, But it was running within the last 6 months, I turn the key, no beeps no fuel pump kicking on, nothing, Turn it to start still nothing, Is there any grounds I could have missed or anything else? Hes gonna be here in like an hour or 2 so Im desperate!!

Its got my Optima from my Yota in it, And I put jumpers on it as well, Door poppers work fine as well as lights

It has been sitting a while, But It started within the last 6 months, before I started unhooking the harness, I labeled every connection and put them all back, even moved the engine ground around to a few places, the metal strap on the back of the motor is good and the body ground is good too

Never figured it out, towed it on the trailer wit my Blazer, She will be missed!
