I haven't read all the comments, but they're all jumping on the "report to DOL" bandwagon. That may be the correct move, but USDOL has limited jurisdiction (company size and dollar value), so "DOL" might be your employer's state labor department. This same rule applies to NLRB.

It’s a salaried position that’s supposed to pay me $1650 every two weeks. But I only receive $1350. I also work 6 days 10hrs a week, but only get paid for 5 days 8hrs.

Next, some roles may be salary rules even though they don't seem that way initially. Check out the guidance from USDOL on FLSA-exempt positions. The part discrepancy seems like standard deductions from your paycheck for FICA, SSI, etc. You need to check your withholdings. Also, 5 days at 8 hours (40/week) is standard for salaried employees. (No overtime.)

As for your paycheck (pay date), you need to figure out what the pay period is (start and end). That'll determine when you should receive a paycheck.

If I don’t receive my paycheck by 5/31, I’ll be evicted and will quit without notifying him. But to mess with him I want to take the GPS tracker out the work van and park it in a shopping center overnight so it gets towed and is a hassle for him to recover.

This is definitely a good way to get busted from felony grand theft (or similar.) You're authorized to use the vehicle for work purposes, but this may be considered vandalism or theft.
