[88 Dolphin cranks but won't start]

So my beast randomly died on me the other day. She was running fine, and the gas was low but not on empty, and she stalled out and wouldn't start as if it had ran out of gas. Put more gas in her and charged the battery and she'll crank but sounds like fuel isn't getting into the system, just keeps trying to crank but nothing fires. I'm not an expert, but I was thinking maybe the fuel pump sucked some shit into it? Any advice is appreciated.

Hey guys thanks for all the help! Turns out the fan clutch was it, and she's running like a champ now!

[No Propane flow]

Hey guys. So I just filled up my propane tank, and hooked up the regulator and no pressure. I tried to open it very slowly since it hasn't been used in awhile, but no luck. Right when I open the valve, I hear a little gas come out but then nothing, so I'm thinking maybe a bad regulator? Any advice is appreciated!

Thanks for all the help guys. I'm gonna go ahead and change the fan clutch so pretty much everything will be new. As of now, this thing has a new engine core, all new belts, new hoses, new radiator, new tstat that I verified is opening, and a new water pump, and I full burped the system. Does great, runs a little hot still, but once I get climbing uphill it overheats. For some reason, the truck is already so hot when I start climbing it has no choice but to overheat. If anyone can help me figure this out thatd be awesome cause I'm baffled

is there a possably that there is still air in the system . fan clutches do fail but the ones I have replaced froze up stuck on all the time not saying it  is not the clutch.

There is a chance. I'm not an expert on it, so I let it run for about 30 mins with the cap off while occasionally squeezing the top hose. And it does seem that the fan is always running, so maybe that's the issue here?

Have you checked out the fan clutch? Did you verify the Toyota thermostat opened before installing? 

The fan clutch is my next guess. It doesnt offer much resistance, so does that mean it's gone bad? And no, I didnt get to check if it opens for sure so I might give that a shot as well.

Update: she was running good for awhile after I burped the cooling system. Was doing great on the highway, in the city, etc. But it was still running a bit warmer than I like (right under the top white line so over 3/4). So just see what would happen, I installed a Genuine Toyota thermostat and burped the system again, and now the problem is worse and even overheats while idling. Now I'm thinking I shouldn't have touched anything, but didn't want her running at max temp all the time. Anyone know what might have happened?

I had the same thing happen with my 78 Toyota Keystone with the 20R engine, which is the predecessor to the 22R.  Some years ago, my 1970 Ford F150 360-V8 had similar symptoms.  On the '78 Toyota I did the same thing: New radiator, new hoses, thermostat, water pump, radiator flush, everything.  The fix?  A blown head gasket.  Also on the F150.  We didn't think it was because there was no interchange of fluids in the motor (oil with coolant or vice-versa), and no outwardly signs of anything, no leaks, etc...  Sorry to say, but it sounds like a head gasket.  Though rare on these, it does happen.  My suggestion is that if you know of a shop who deals exclusively on engines take it to them and get their opinion.  Toyotas usually run cool when they are running fine, even under a load, so don't get complacent thinking that if you just remain below the red mark you're fine, you should never get that high a reading.

I thought that too, but I just had a new core installed not even 2 days ago by a professional (?) mechanic. I would assume it would have a new head gasket, but I am by no means an expert. Would a new core have that, or would they check when installing? And same thing on mine, no oil in the coolant so I had ruled that out. I burped the system to be sure last night but haven't gotten a chance to test it.

Hey guys. So I've got a 89 dolphin with 4cyl 22re that's running a little hot. I've done full radiator swap (new 3 row radiator, new thermostat, new water pump, new hoses), and recently had to replace the core because of a rod knock. All said and done it's still running a little hot. Gauge reaches 3/4 temp when on the highway doin over 55. Im pretty baffled now, is this thing doomed? Appreciate any advice.
