Check your fuses for the turn signal - also the relay unit could be bad - these are located drivers side just below the steering column (there should be a removable panel there) - I have an 89, and that is where it is on mine.- google aerostar fuse dia and you should be able to find the fuse box layout, so you know the ones to check.

I would have said to check a bulb, but since the flashers work, you know it's A) not a bad bulb, and B) not anything with the wiring...

Good Luck

it will not be a chain as you blew out the cylinders to get rid of the excess fuel by turning it over
no-- I would be looking for problem with the injector control, fuel pressure
if you have spark and compression then the thing missing is fuel

First locate the fuel tank then from there two small fuel lines head towards the front one of them will be connected to fuel injectors which is return pipe leve it as it is. Other one is the main pipe which goes through water seperator, fuel filters, speed pump, automizer pump and then to injectors.
Just remove pipe and blow air to clean, drain water, replace filter if cloged and also clean fuel tank if you find more dust inside the pipes or filters.

may be it was not the MAF sensor but bad connections in the wires. Have a technician check the voltage in the wires and connectors to determine if that was the fault to start with

The fuel pump is in the tank, so you would have to drain and then drop the gas tank.
