Ignition Module???

[plowboy]

In my expierence if there is fuel in the oil it usually caused by cranking a fuel injected engine for long periods of time with no ignition and flooding it. The injectors keep squirting fuel in and it eventually drains past the rings into the oil pan. If that has happened, change the oil. I had to learn this the hard way.

Past GM's I have owned if you held the gas pedal all the way to the floor it prevented this if you were cranking for an extended period. I am not sure if that works on a Ford or not. Haven't had to find out yet.

Where are you checking for Spark? At the plug? at the dizzy? Is it a weak spark? If you have flooded it badly enough to get fuel into the oil, I would change the plugs. Most likely they are too fouled to fire. You may have spark down to the plug, but it may not fire itself. I have flooded them badly before and tried to dry them out. Even baking them in the oven, but it never really helped.

Something else to check would be the MAP/MAF. Someone correct me if I'm wrong, but I think the 2.9's have a MAP (Manifold Air Pressure) sensor. A faulty MAP can cause the computer to screw up the air/fuel mixture. Although I'm not sure how you could have fuel in the oil(flooded) and have dry spark plugs. Something doesn't sound right there.

Another sensor check would be the throttle position sensor.

MAP, O2, and TPI sensors can be checked with a volt meter. I would give you the process, but my book and testor is packed away because I am moving in a couple of weeks.

Hope this helps some.

PS What tek said above this post is correct as well. Someone have a process for testing the regulator?

To check the fuel regulator pull the vacuum hose off it and first check for gas in the vacuum line. Then put a hand vacuum pump on the regulator and set about 18 to 20 inches of vacuum and check to see the regulator holds the vacuum and doesn't bleed down. If it does replace it.

If you have spark and you have fuel I would suspect it has jumped the timing chain. The fuel injectors are told to fire by the module or a crank/cam position sensor (on newer models). So they are still getting a signal to squirt fuel. Find TDC (top dead center) for # 1 cylinder and look at where the rotor is in comparison to the # 1 spark plug wire. If they don't line up within one plug wire that will tell you if it has jumped.
