need help, wagon wont start
 

hey guys i had been driving my wagon for a while with no issues but i had to park it cause the tags are now out of date but it was running fine when i parked it. tried to start it up the other day and nothing. the battery is dead and woth hold a charge but it still wouldnt start with jumpers to it. it trys but got backfires and just crancks.

How long was it parked? Any other work done to it just before parking it?

No just tune up stuff that I did before driving it a bunch. I live on the coast so I'm wondering if something corroded or is just wet in the ignition system. I took the cap off and gave it some compressed air but still nothing

Backfiring suggests either firing-order is wrong (plug wires crossed??) or worst case maybe the camshaft timing.

Look real close at the distributor cap. Tracks across the smooth surface can make it much easier to short. With the engine cold, before dawn when it's still completely dark, have someone try to start it while you watch for arcing across the cap or around the plug wires.
