86 toyota pick-up won't start

Hi

I've had my truck off the road for a couple months and am trying to get it up & running again. I blasted the carb with cleaner and it will start but will only run for a couple seconds. When it is running, it will conk out as soon as I give it gas.

Does anyone have any ideas?

Thanks

Could be your fuel filter or fuel pump.

Carb may also need to be adjusted.

Have you checked your plugs, wires, and distributor cap yet?

You might want to check for evidence of mice, i.e. chewed wires. I bought a car that had been sitting for quite a while, and I found a mouse skeleton caught in the wiring of the engine compartment

If it really IS loading up on you with too much gas, by pulling a plug, this will be obvious with black carbon on the plug.

If you have a regular older style carb, and it has an accelerator pump...if that dont't work the engine can die upon throttle application, but otherwise cruise for you just fine.

Also, if this older vehicle has a carb with a choke, make sure it is open all the way when warmed up.

Have someone follow behind you to see if any black comes out the tail pipe.

Make sure your engine is not retarded.

Try cleaning MAS sensor

Not sure if the 86 is purely carburated or is throttle body. If it has a Mass airflow sensor, blast it off with some electroclean spray - the non residue type.. No oils or lubricants. You may be getting a goofed up fuel mix based on a mis-sensing MAS sensor. Worked on my 99 taco. I used K&N oil type air filters. The oil gets through and fouls the MAS sensor.
