2008 Challenger 180 won't start

[cjburt22]

Need a little help here. I had someone bring me a Challenger 180 in a million pieces where someone was about to replace entire engine. After sorting everything I had everything necessary to put it together. They brought me brand new SBT engine, SC, oil and water pumps with new front cover all still in the box. Anyway everything went great and I completed the build and now when I attach DESS key the gauges light up then flash SENSOR, then it goes away. I don't have a set or mode buttonon this boat to push 5 times to get code so not sure how to do that. Anyway when I press the start button the solenoid clicks over and over while I hold the start button but never attempts to start. I went ahead and replaced the solenoid to eliminate that and no difference. So 2 questions...
How to read a code on the Challenger boat?
And what does the rapid solenoid clicking mean?
I did connect my start box with a start button on it to the starter and the motor turns over but slowly.
Any help will be appreciated.
Thanks,
Casey

I was able to get it to start turning over. It was an issue with the battery switch. Now it's not starting. I know I have fuel up to the fuel rail and I have spark. It turns over good and every now and then I hear a strange noise. I can't determine if I'm getting a back fire or what. I did get a cam case sensor code once but it went away.

Ok it's definitely back firing and when it does it throws that po344 code. Any advice on what I may have done wrong on assembly. I call myself following the manual to the T but that doesn't mean I didn't do something wrong.
