Car won't start
The questions, Why all the thermostats? has it been overheating. If so that would explain issues causing a NO start. If its never overheated I need more info about the Pacifica. I could only make a guess.
Amanda, it is not impossible that something was bumped or unplugged when the job was done, but you are going to have to start from square one. what type of no start, no power at all, does the engine turn over? you will have to test for spark and fuel. also, scan the computer for codes.
