Intermittant Fuel Pump Priming

[TimboSHO]

About a week ago I remember hearing my fuel pump prime a couple of times when the car was just sitting there with no key in the ignition. Last night when I went to start it, the battery was completely dead. I'm curious if anyone else has had a problem like this. I assume that the priming fuel pump is what killed my battery, because today I did a load test and charge test on the battery and alternator, and everything is fine. Also, the parasitic draw is only 7mA, which is really good. But when I was testing it, the fuel pump didn't come on at all either. I was just wondering where to start, or if anyone else has had a problem like this. Thank you.

Most likely, the IRCM is shorting internally.

Mine will do that if I get it wet and will run the fans when it should be off. I dry mine out and it's okay until the next time.

When I am breaking and I put the clutch in, it dies some of the time. Would this be another symptom of a bad IRCM? I pulled it off and stuck it inside for awhile in case there was some water/ice in it, but i couldn't figure out how to pry it apart without breaking it. Also, when driving sometimes the car jerks like the fuel is completely cut off or something.

By the way, can i get an IRCM out of a regular Taurus as long as i get another 'M?' Thanks!

Falure to maintain idle is often the IAC.

Bucking/jerking is often a symptom of a flaky CID sensor. If could also be the result in fuel pressure. Onaly a fuel pressure test would show for certain.

It was definately the IRCM. I put a new(junkyard) one in today and no more intermittant fuel pump. Also, you can only get the 'M' module out of a SHO. The regular Tauri have CB, J and K. I checked every single Taurus in U-Wrench-It to figure that out!
