Cranks, but won't start!!?

I have an '00 LS v8, changed the oil & air filter and now it will not start. It's got 135k+, fuel shuttoff switch is not tripped. Any suggestions?

did you disconnect the MAF when replacing the air filter

Yes, and that was one of my first checks. Unless wires have pulled loose inside that's not it. I also disconnected the battery to clear any codes that might have been created.

Thanks

did you spray any cleaner on the MAF? How about the throttle body, did you spray any cleaner in it?

Do you have a multi meter?

Solved it....I did not spray anything, while apart. After spending all day w/the kids at an ice rink, I sprayed a little starting fluid into the air box and it tried to fire, which told me it's a fuel problem. Started checking fuses, and found the fuel injector fuel had blown. Why? Don't know, but it does start now. Hopefully it's cured, time will tell.

Excellent.
