ok, so i bought the warrtalon stage one. everything went well with the boost gauge, MBC, and the exhaust. after a few days (waiting for a few days off in a row) i sent off my comp to be reflashed. i installed it when i got it back 5 days later, and the engine wont start. there is no fuel, no spark, no nothing. i have checked to make sure all ground are still there, and even tried to pull codes with a scanner but no luck. i had my computer sent back to dynoflash, who said the computer seems to be fine, but it still doesnt work. i am at a loss what to do. i have called mistubishi, they said tow it here and we will look. i do not want to go through the hassel of putting it all back to stock, paying a few hundred to get it towed there, and have them tell me "we donno". i have searched but found nothing familiar in the site. the car is an evo 9 mr with 4k, only mods are the warrtalon stage I.

 

I know this is basic, but did you meter the battery for voltage?

 

yes, the voltage is fine. the car still cranks over like normal.

 

double check the harness to ecu connections?


check all the major fuses

 

i have checked all the fuses i can find, and are currently checking on the relay. i also have pulled the plugs, they look good, motor still has compression. only thing im missing it seems is the ok from the computer

 

I think something happen to the computer. Think about it.... the only thing you messed with was the ECM and its connections, your problem is somewere around there. Its not the fuse's or relays.

 

still, he did do some installs under the hood. so you can't rule out a short.

I wonder if it is the immobilizer, I would think Al sent you the same unit back.

the battery thing is a good thought, a low voltage could be the prob.

 

battery is at 12.3 vdc.

stiil can't find anything. I would think it it was the computer but I sent it back to AL. He said it was fine and I reinstalled it, same result, cranks good, no fire.
I don't know what to check next.

thanks

 

Do this: Disconnect the negative on the battery for 10 MINUTES. reconnect, start the car; DONT touch the gas. Let it idle for 10 MINUTES, then you reset the computer. (wont mess with the flash). Give that a try, should start up.

 

Hmm, you need to find someone around you with EcuFlash and a tactrix cable. They can try to install a stock 06 map for you with your immobilizer code to see if anything changes.

 

So your car was running fine after you installed the exhaust, mbc, and boost gauge? Did you drive it around? If that is the case, then it must be the ECU.

Please do not take your car to the dealer until you know for sure what is wrong with the car. I do not know the dealer you got the car from (I hope it is HB Mitsu), but the moment the dealer checks your ECU and sees the flash, your warranty might go poof.

 

I pulled my ECU out of my car, to get the injectors scaled on it. had the box out for 3 days, and then put it back in, DID NOTHING BUT THAT! (I didn't send it out, as I didn't have my injectors yet) I plugged it in, it drove for 50 miles, and then quit! Wouldn't start etc... I DID have it towed. I went to the dealership BEFORE they did anything, and did the battery thing I mentioned, and ALL IS FINE NOW!!! I pulled out the ECU with the battery plugged in. caused a problem. Try this first, you might be fine!!! I WAS!!

 

If it cranks and doesnt fire, and the only major difference is the ecu, then I would suspect maybe the immobilizer code is wrong..

 

Or for an extra $29.99, you can get the Wartallon/Buschur Captain Krunch decoder ring!! jk do the battery.

 

Mine did Exactly the same thing, and I got it towed after it ran GREAT for 50 miles. dont know how or what. The only thing I did was pull out the ECU, and plug it back in a few days later. it would turn over, it was almost like the battery was dead. had the "click-click-click" of a damn near dead battery.
