Wont Start!!!!

[fieromatty]

i just rebuilt the ls1 from my 97 automatic corvette... it has been driving around for about a month but it died... and it died hard. I dont know what happened but it wont start anymore... its getting spark its getting fuel... the tach moves and sometimes it does start up but it will only run for like 5 mins... if you put it in gear it dies... the computer reads at 128 psi which i think is the max readout..... when i put my foot on the brakes when the car is completely off.... the interior lights kick on.... i cant figure it out....its crazy where do i start.... the engine rebuild was done by a shop

Check the battery. Sometimes a bad battery will make all kinds of crazy things happen. Check grounds and charging system.
