SOURCE: Carb gas pouring out of hole on top front of carb

Sounds like the float has absorbed gasoline and can't ftoat anymore. This causes the fuel to not be shut off when float bowl is full causing the carb to flood. You will have to buy a carb kit and a float and rebuild the carb. Hope this helps.

YOU HAVE DIRTY INJECTORS WHICH IS STICKING OPEN CAUSING FLOODING .WHEN YOU TURN OFF ENGINE.THE INJECTORS KEEP LEAKING. YOU NEED TO CLEAN INJECTORS.BUY A BOTTLE OF FUEL INJECTOR CLEANER.FILL UP FUEL TANK. POUR INJECTOR CLEANER IN GAS TANK. DRIVE CAR AROUND SO THE INJECTOR CLEANER WILL CLEAN OUT INJECTORS.

your shift cable is stretched or broke. try starting in nutral. if this doesn't work you need to adjust or replace shift cable. this is a very easy fix but it should start in neutral.

no the transmission shift cable is streached and needs to be adjusted. you should be able to shift the van to neutral and start it in that gear. just watch when you park because it will roll away. use parking brake. if it doent start in neutral then your cable may be snaped and not noving the gear selector on trans at all

Takes long time to start
I may need a tune up. You might try filling you take with gas and then pour on some STP or LUCUS FUEL INJECTION CLEANER INTO THE GAS TANK. You nay have blocked fuel injectors or fouled spark plugs.

Engine stalled out,would not start, pour gas in carb,cranks,keeps running,until idle falls below 12to1500rpm,than stalls out again and will not crank,repeat gas or starting fluid in carb,cranks runs and...
This truck is fuel injected, the problem sounds like a weak fuelpump, it runs when you pour gas into it until that gas runs out, the first thing is to test the fuel preasure, if the pump is weak it may run with gas poured into it but wont idle, also a common problem is the coolant temp sensor and the ground wires to thermostat housing bolt but i wont bet its the pump inside the fuel tank, if you put a fuel gauge on it there should be at least 55-61 psi if its a few pounds lower it can cause problems, you have everything else and it runs with gas poured so its a fuel problem check the preasure, theres a valve up top on the fuel line to connect a fuel gauge to it, start there hope this is helpful.

Check the fuel pump.
Check the fuel filter.
Best would be to also clean the carburator.

generally such problems occur due to sensors, it may be your vehicle's crankshaft sensor. have it checked.
