Dave1647545494 Posted November 16, 2009 Report Share Posted November 16, 2009 pcm controls all engine functions if by bypass you mean remove all electronics and switch to carb then the answer is yes if your not that motivated the answer is no what kind of trouble are you having?

rl Posted November 16, 2009 Report Share Posted November 16, 2009 CCRM (Constant control relay module) is by the radiator and it controls a bunch of stuff. In theory you could bypass it, but it would take a lot of wiring and relays be be a complete mess. Quote Link to comment Share on other sites More sharing options...
Dave1647545494 Posted November 16, 2009 Report Share Posted November 16, 2009 my digram on mitchell shows it covers pretty much anything that takes a relay including the pcm, cooling fan, and a/c compressor Quote Link to comment Share on other sites More sharing options...

It would be fun to watch someone try to bypass it though. Quote Link to comment Share on other sites More sharing options...

Guest Removed Posted November 16, 2009 Report Share Posted November 16, 2009 only thing he is having a issue with is fuel pump relay. if every thing else in it is working properly, then add the fuel pump relay, but like i told you on the phone, it also sends output to the pcm. that or pm me your vin & part number off the ccrm. i can buy ford parts at dealer cost.
