Help!

'94 Aerostar, 3.0 auto 2wd, 165k miles

Running a little rough at higher rpm so I replaced the fuel filter.

Now she turns over but won't start.
No spark on any plug wire.
No codes besides 111

I've replaced the cap, rotor, TFI module and coil. Plugs are still young.

Started only once after I replaced the cap. Ran for a minute with a bit of peddle then it quit running with I let off. No spark after that. Got a code 212 and then I replaced the module and coil. Code is cleared but still no spark.

What to do next?

 

I would guess that the distributor is bad. In my history with distributors the TFI is usually the culprit, but It could be the distributor itself.

 

Thanks for the tip. I may try that next but it's in a really lousy location to work on.

I suspect ford only intended to put a straight 4 cyl in this design. worst vehicle I've ever worked on so far.

 

may be the Hall effect sensor plate, sensor under the rotor or wiring connector got damaged when changing the rotor. check with a mirror or pull distributor.

I have not swapped out the distributer yet, but I'll see if I can do the test mentioned in the article. Thanks for the info.

I've learned how to work on this heap while leaning over upside down between the front seats. What were the designers thinking when they came up with this arrangement? Now I know why every Aerostar forum has instructions for removing the engine! I have two 302 engines sitting on the bench but this truck is far too rusty to bother swapping one in.

Cheers!
