Hello fellow fordies.
I have a 2003 Escort zx2. The car has a parasitic draw and i did a draw test and nailed it down to the fuel injection system. If I remove the fuel injection fuse at night, (the one under the hood) the battery is still good in the morning. I plug it back in and drive. I've never had a check engine light come on but the battery light comes on at idle, then off when rpm's are up. I had the alternator checked and supposedly it's good, putting out 37 volts/amps, whatever. So know I need to figure out what in the injection system is acting up. Could it be injectors, fuel pump, ECM, CCRM? A​​​​ny input on this conundrum would be greatly appreciated. Also the wiring seems good.

 

Check CCRM pdf below.
And what happen if you unplug the alternator's electrical connector (3-wire plug to your voltage regulator) overnight?
Remove the voltage regulator, attached by 4 torx bolts to your alternator, then you will see 2 pieces (spring loaded toward the center of your alternator), this 2 pieces (brush) how long are they, 2-inch? 1/2-inch or 1/4-inch? To install the voltage regulator back to your alternator you need to press the spring load brush in and install this side first, then attach the base and secure the 4 torx bolts.

 

looks like I've still got a lot of work ahead of me
Thanks

 

Check the brush that doesn't take too much time. If something is going bad with your alternator the voltage regulator brushes would be the very first thing to check. Your alternator may last 20 years but the brushes on voltage regulator, like brake pads, will be worn out and need to be replaced, so the lifespan of the brushes can be 30k to 100k miles.
Yes, that CCRM.pdf will take you long time to go over, you can skip to the section that's relevant to the fuel system.
