I change the fuel pump it wasn't that I changed the cam position sensor it wasn't that I checked the crank position sensor and it seems to be getting a signal although I didn't change it I check the spark and there was no spark what if I shoot a little starter fluid it seems like it wants to run but not like it normally would if you shot starter fluid in a vehicle I checked the two fuel pump relays in the passenger compartment driver side fuse panel they seem to be functioning the first one clicking when I turn the key on the second one clicking after I turn the key is the 3 inch by 2 inch ECU in the fuse panel controlling Spark fuel pump injectors timing does the cam position sensor and crank position sensor go through the ECU are there any other relays in the fuse panel under the hood for the fuel pump different diagrams I check online seem to show a different location for the 04 let me know thanks

When I call the dealer parts department and the service manager they really don't want to tell you much cuz they want you to bring the car in I guess but he did say that the ECU under the hood was like $1,100 I don't know if he was confusing that with the ECM but he said if I got one from him or one from a junk yard that I had to reprogram it to that vehicle can I just plug in another one that's like a fuse no cuz I can get one of those for $50 at the junkyard and the guy said even that one had to be reprogrammed to my vehicle is that true let me know thanks I hope my son Wat detailed information helps you guys thanks

You need to program the keys to the new ecu, it wont start without doing that due to the security system.

Are you freaking kidding me Dan the whole time I was trying to get this thing running I was using a regular steel key without the buttons on it so are you telling me because of my security with the key and not using that key that's why my car wasn't starting because I took the key locked it and unlocked it got in and it started so my fixed is that what the problem was really something as stupid as not using the key with the button let me know thanks man I appreciate it
Mitsubishi Mechanic: Dan, ASE Certified Technician replied 1 year ago

It should have a chip in the key and an immobilizer ring on the ignition switch. Only if the ecu is replaced will it need to be programmed to the key.
