I notice a few say this don't work. First you MUST follow the procedure to the letter. I fought my 2005 Silverado for 3 days. I did this procedure and it fired right up. Don't get over anxiuous. Thanks for posting my Chevy runs great now.!!!
Is this a substitute for flashing it?
I wanna replace in 2001 Tahoe 5.3 what pcm can I use and will this method work with no trouble codes
I have a 2010 escalade…i changed the pcm now it wont crank or start..i did the security relearn and still nothing.. All lights work i did a junkyard pcm swap. Do i need to have the vin programmed
I have a 2004 tahoe. One day I was driving and it completely turn off, the stearing wheel got hard and breaks also. Try to turn back on but no response. The truck wont crank and has that theft lock on the dash everytime I put key in ignition switch. Do you think it has a bad ecu and may have to switch it?
i have an 04 envoy – will this work???
hey does this work on a 06 Colorado?
did not work !!!!!!
i tried this with my 1998 k1500 5.7 vortec. put a preprogramed ecu from flashmastersecm.com and follwed the about procedures. works great
did this with my 2005 silverado 2500hd 6.0 got it to start and idle but would get to 2000rpm or about 10mph and the truck would spit and sputter rpms dipped and would almost stall any idea what's going on there?
what advice can you give me for my 1990 silverado 4×4 is it the same procedure? my truck cranks but won't start im sure it's the ecm this has happened before now same problem again the mechanic that screwed me 400.00 told me it's my ecu
sir I have yukon 2008 5.3
ECU broken …..
can I use new one and sets it up by myself? through same way ?
I have a 2005 Silverado with the 5.3 1500 4X4 and I got a used PCM from a 06 Tahoe with the 5.3 1500 4×4 and the number match mine. As soon as I installed the PCM and turn it to the on position it turns over like I'm trying to start the truck. Any reasons why? Maybe it does have to be flashed by GM.
so did it work?
Will this work to remove a hp tune?
I have an engine swap project! I have an 04 5.3 with 04 ECU and harness! will this method work???
