85 FJ60 cranks but will not start.

An issue has developed on my cruiser. I filled the vehicle up after it had sat for a while, and as I'm driving back to the house, it blew off some lines from the air cleaner. This caused it to die as I'm sure you can imagine. I got the lines stuck back onto it, which gave me just enough time to get it into the autozone parking lot. I replaced one of the lines that blew off, started it back up, and as soon as I turned the air conditioner on the engine died and has yet to restart.

The cruiser has sat for several more days as I've been wrenching on it, but it seems that fuel is not getting to the carb. I checked the fuel filter, and it seems fine, but I'll go ahead and replace it anyway. So I decided to check the fuel pump, so I pulled the send line off of the fuel filter and placed it into a bottle to see if any fuel came out. I then remembered that its a mechanical fuel pump and I'm an idiot.

My only real question is this; Am I on the right track, and is there anyway to tell if the pickup in the fuel tank is clogged without dropping the fuel tank itself?

EDIT: Just realized saying that lines blew off of the aircleaner and not showing which lines is kind of a dick move. Here they are circled in red.

There is a sight glass on the front of the float bowl on the carburetor, you can see if it has fuel. If that's too dirty you can always pull the hard line off (17mm hex) on the front of the carburetor, place it in a water bottle and have someone crank it.

Make sure there is fuel and make sure there is spark, if you have both of those it may still be a vacuum issue.

If it backfired and popped some lines off there is a chance it popped another off or split it and that could be part of it.

There is a process in the FSM to turn on the fuel pump. You use a small jumper wire on the Service Connector. This will thurn on the pump. Then you can feel for pressure in the fuel line at the filter.

^ 2F. Not 3F-

The question is: why did the engine backfire & blow off the hoses in the first place? That should never happen. Usually a backfire is caused by a lean burn - lack of fuel.

As mentioned-check for other hoses that got blown off too. Often the PCV plumbing hoses on the passenger side can blow off from a backfire. If they did, the engine wouldn't start.

You'll only be able to check for proper fuel level through the sight glass on the carb while the engine is running.

Thanks for all ya'lls help. I do not remember hearing it backfire, but before it died it tried to die on me as I let off the clutch changing from 1st to 2nd. I then put it in 3rd and it died. It cranked right back up after this, as I put it in first it died again and that is when I noticed the lines blew off. At some pint I'm going to have to go back through and replace the vacuum lines since half of them are not in good shape anyway.

I can't figure out how you got positive pressure into the air cleaner, is that blown valves and head gasket ? Better do a leak down test first.

This is an extremely late response, but I still have an issue with the PCV hose coming off. Something in there ain't right. I don't know what though. The issue was the fuel pump. Couldn't handle any load on it what do ever.
