The engine control module is required for the engine to operate and can not be bypassed.
when you open the hood of your 1991 Jeep cherokee, look at the right side fender( drivers side) you will see a black box mounted to the fender well behing and next to the air box,. that is the Electronic Control Module ( ECM). I hope this helps.
1987 and up will be interchangeable, although there might be some reflashing of the ECM required.
Boss uses buffered bypass, not true bypass.
If the compressor is locing up I belive you have two choices (1) look on the belt routing digram under the hood I belive it shows belt routing without ac unit, I think you can buy a belt for a non ac jeep & just route the belt to bypass the ac unit-you will have to try it! (2) in the power box you could remove the ac relay to stop cycling of the compressor. as long as the clutch free wheels this will work, I have done this myself without short term issue.
First of all what is the problem you are having? The main thing the ECM on this vehicle is controling is the fuel richness. In other words if the ECM is not working then the jeep is either not running or not running well ie.. too rich (black smoke) or to lean. The stock carb is garbage and should be replaced with something like a motorcraft 2100 ( better than weber) and do nutter bypass. with # 49 jet should pass inspection. Nutter bypass will bypass ECM and run much better.
No. Too many differences between those years.
You need to be more specific. What about the ECM are you testing?
Does the ecm control charging system on a 93 jeep wrangler and cause it not to charge the battery
Is there a way to bypass the ECM in a 1993 chevy s10 4.3 vortec
No you can not , That is what makes and keeps the engine running
No. The ECM not only actuates the fuel pump, but also adjusts the rate at which it pumps fuel.
No, the ecm is set to operate only 6 cylinders, you need the ecm from the vehicle you got the engine from.
Are you trying to put a V8 in it or what. If you are keeping the original motor in it, the answer is YOU CAN>T
