Mechanic Job in Rainier, Washington

Of these 3 vehicles I need my suburban or Astro van running. The suburban turns over but doesn't start. I have replaced the plugs and wires but it still doesn't start. I don't have the time or the knowledge to continue to troubleshoot the issue. The van has been sitting on my driveway for about 2yrs. When I parked it there was metal on metal sound. I'm sure I need the do a front end brake job. But it docent help it sitting for 2 yrs.
