Not a great weekend

What a crappy weekend....

Lets start Saturday morning around 10am. I finally have everything together to get my car running after three years of sitting. I get a friend of mine to come over and help wrench on it to get everything together to fire her up. So in between afternoon showers and 100 degree hear and 100% humidity around 5pm im ready to hear it. I pull the injector fuses to verify oil pressure without drowning the cylinder with fuel. I put them back in and turn the key and nothing, just turns over. My friend tells me I have fuel coming out one of the injectors o rings. I change that out real quick and at least I know im getting fuel at the rail. Tried to start it again and nothing.
Knowing im already getting fuel. I go to start checking for spark. Checked #1 and nothing, checked it at the coil and then opti and nothing. So I thought maybe the icm is bad and since I have a good one on my other z28 I daily drive I pull the coil/icm assembly off. So..I swapped it to the other car and nothing. I go to put it back on the daily driver and move the car and now that car wont start. Im like...wtf. I verify I put everything back where it goes, made sure the grounds were in the right spots and tight. Nothing....So now I have not one LT1 down but two. I could have worked on it today a little bit heat makes you lazy and it was just too damn hot. Sorry for the long rant but it been one of those weekends.

So....how was everybody else's weekend. Good I hope.

I was working on my regal and I needed a shorter 18 mm wrench so for a stupid 4 in wrench they wanted 8 bux wth. Now that I can get to the nut I cant get enough tq on the nut to get it to loosen up WTF.

Mean LT1, check you opti harness connector ends and make sure your coil has power, it sounds like the PCM isn't telling the coil to fire.

Thank you for the help. But why would it happen on both cars, thats the part that is stumping me.

I feel your pain, spent all weekend in 100+ degree heat working on my wife's C4 and the POS still won't fire. Worst part is I've run through all kinds of suggested tests from others helping me troubleshoot and everything seems to check out, yet the damn car won't fire.

I can send you an ICM to put back on your DD. If it starts then you know there's something in the new setup frying the ICM. You could also try having the two you have tested at the local parts store.
