What do trouble codes 67,81, and 82 mean for a 1993 Chevy Astro Van? THX

Does it blow if the compressor is unplugged ?

loosen fuel lines at throttle body when turning key to on possion , careful not to spill gas all over engine, do you hear fuel pump running and try to put at least 4-5 gallions of fuel, you could try a (LITTLE ) shot of starting fluid ?good luck hope this helps.

With a testlight you can check every fuse in the box without pulling a single fuse in about 10 minutes.
Find a good ground for the testlight near the fusebox. The tops of the fuses have a little opening on both ends that accept a testlight's probe.
Start by turning key to on (engine off), and turn lights on. Now every fuse in the fusebox will be powered. You touch the probe into both ends of each fuse to test them. Good fuses will light the tester on both ends. Bad fuses will only light up on one end.
Good luck.

have system scanned to get trouble code

If You can start the vehicle off ether only then you have a fuel issue. the pump is working and the fuel pressure regulator is too. so either the injectors are not getting an electrical signal to open and close of possibly, Your oil sending unit is defective and has shut down your fuel system (a safety).

Also check all of your grounds, a little corrosion caused the same problem on mine. Just had to find the right ground. Mine was on front under pass headlight causing mine. Good Luck

Has the 'Check Engine' light come on? I had this problem at 30,000 miles and the trouble codes set were transmission component slipping. Ultimately required replacement of the transmission.
