Since as you've said you have no relevant job experience, your educational experience should be the focus of your resume. And don't worry, at this point in your career you don't need job experience to get a co-op/internship position, what you have is potential. I didn't even realize you were engineering looking at that resume you posted, let alone mechanical. List your school with Bachelor of Science - Mechanical Engineering and the date you plan to achieve that degree - i.e. "Expected Spring 2014" or whatever. List any actual engineering classes you've taken thus far under "Relevant Coursework" or something. List stuff like Solidworks, Matlab, Excel, Word, whatever under "Related Skills" or something. I wouldn't put a GPA on there under 3.0 - they'll probably ask at some point and you can explain your situation then. List the jobs underneath that. Even if you would consider them irrelevant, we learn something in everything we do, and it shows you have a history of being responsible enough to be employed. Just some random comments. Personally my resume sucks - it's just a list of degrees and job descriptions. Someone in a hiring position could give you much better details on how to gussy it up with all the buzzwords and key phrases and whatnot.
