Is there a fuse inside the ECM ?

The abs is dirty on the inside and needs rebuilt

You need to adjust the Switch, it thinks you are in Gear

Hi,
Ok first you need to make sure that the battery was put back in correctly. Positive terminal to positive battery cable.Then if that is correct, check the main fuse's right next to the battery area, they are large and square ensure non of these are broken, or fused.Check all the fuse's in the other fuse box in the engine bay area and also inside the vehicle.
Let me know how you get on.
Thanks

Thanks for choosing FixYa and welcome. Since you have power inside the car, the battery and power connection should be good. You still want to make sure you have the best possible connection because if the starter isn't getting the correct amount of volts, it won't turn. So clean your battery terminals and post to make sure. Check your ignition fuse too. It should be labeled and shouls be located in the engine compartment fuse box. You may have a bad starter if the two steps before check out. You can take a hammer or pole, just something to make contact with your starter. You want to tap it five to seven times. Then try to start the van. If it starts, you have a bad starter and need to get it changed. I am thinking it is the starter because you have been having starting problems. Hit it and see if your van will crank up. Let me know what happens.

those two codes are for the o2 sensors. both are the upstream sensors on the front and rear banks. so they are desinagted bank 1 sensor 1 and bank 2 sensor 1. them most common cause for this is faulty o2sensors , bad gas and of a poor running engine. so if your car runs good (no misfire) and gas is ok then replace the o2sensor witch is the very most common cause.

Take all the fuses out and check them one by one and re install them and replace the blown fuse .
Tap on the relays to unstuck them .
Clean the batery terminals with sand paper .
Check the rear light and brake bulbs and sockets.

the O2 sensor on you van will not cause the engine not to start if you are moving the fuse block under the hood it sounds like a bad connection in the fuse block i would start looking there first

fuse #10 in the fuse box inside the van under the dash this fuse will be blown HOWEVER the reason the fuse is blown is your real problem
the most likely cause is the reduntant bps on the master cylinder just unplug it and the fuse should stop blowing.
you can replace it if you want.
be very carefull of leaking brakefluid on harness below this sensor if brakefluid has leaked into harness and is not attended too it can cause major problems.

I had the same problem with my 2000 Windstar. It ended up being a brake fluid leak around a sensor on the master cylinder. The sensor is a known issue and has been redesigned. The brake fluid dripped onto some elctrical connections causing fuses to blow. The sensor turns off the cruise control when the brakes are pressed. On some vehicles it was known to cause fires and Ford had to provide a recall. At the time my Windstar was not covered in the recall but it may be now.

The problem is simple and you could possibly repair it yourself. the sensor on the brake master cylinder (front side protruding down from the bottom) is shorted out. This sensor turns off the cruise control when the brakes are pushed. You only have to unscrew the old sensor and replace it with the new one. You will notice that the old sensor has has brake fluid all through out it. this is the reason for the short. BTW you will lose a little brake fluid in the process so have the new sensor ready when you take off the old sensor. I know this doesnt sound like it could possibly be the reason but it is. hope it helps
