I have a stalling problem. It stalls at any speed and there seems to be no rhyme or reason as to when it stalls. It stalls at all speeds. The kicker here is that it is normally hard to start right after it stalls and usually I have to let it sit for a couple minutes before it will start again. HELP!!!!!!!!!!!!

Well, after many hours of work and time in the shop, here is a list of what has been replaced. It was determined that I was losing spark and it was not a fuel problem. We replaced the plugs, wires, cap and rotor. They were really bad and needed to be replaced. We also replaced the Ignition control module and then it was still stalling. I finally got it to stall at the shop with the mechanic and the code showed that the distributor was failing. So the distributor was also changed. The wiring was traced after this and the mechanic found singed wiring on the Distributor Connector. The connector was tested and a short was found, so the connector was replaced. I have also changed the intake manifold gasket, the mass air flow sensor, the fuel filter, the water pump, the hoses, the belts, and the oil pressure sending unit. It is a lot but it all needed to be done and I am glad that I will be getting my van back in the next couple of hours.

Hope all will be working good for a long time. Thanks for the update.

Man, this van has not run this good in a long time. I am so glad that she is fixed and running. Now I can put the money into the cleaning and painting instead of the running.

I used to drive aerostar for many years. stalls on road? may be when hot? man, seems to me TFI is bad. On my aero it was on distributor and did conversion... now TFI is near radiator, in "cool" place. 7 long wires, 2 used connectors, a hour of work.

How to be sure... well, people say U need oscope to be sure PIP voltage is enought, but... U can use LED with 1KOHM resiator (on TFI pin#1), but when engine is hard to start check for fuel pump zzzzz sound in 2-5 sec. after starter cranks engine... if ZZZZ sound appeares, PIP pulses are good... So check for spark.
