Dansilvy75 Posted April 28, 2014 Report Share Posted April 28, 2014 Ok, I'm putting a 2013 5.3 engine in a 2008 Silverado, I'm using the 08 silvy harness because the 13 was bad, everything going together perfect till I plugged in the crank sensor, the 13 engine has what looks like vvt, it has an extra tiny plug in that my 08 harness does not have, how can I get around this, I'm thinking maybe change cams and timing cover? Will this work or is there an easier way? Does it have to have that can sensor plugged in to run correctly or?? Please any info will be appreciated Quote Link to comment Share on other sites More sharing options...
Blown 346 Posted April 28, 2014 Report Share Posted April 28, 2014 Without the cam sensor the computer will have no idea on what timing is. the motor will not run. Yes you do need that. Quote Link to comment Share on other sites More sharing options...
chpspecial Posted April 29, 2014 Report Share Posted April 29, 2014 Actually the engine will run with out the cam sensor. It will also throw several codes and potentially missfire. Its the crank sensor that won't let the engine run. Sent from my HTC6500LVW using Tapatalk Quote Link to comment Share on other sites More sharing options...
chpspecial Posted April 29, 2014 Report Share Posted April 29, 2014 I don't remember what the default on the vvt set up is when there is nothing plugged into the engine side, the truck can potentially be in vvt without a signal causing it to run rough. There are two options. 1, wire in the vvt to your pcm and use a vvt calibration file, or do the vvt delete to the engine.

Dansilvy75 Posted April 29, 2014 Author Report Share Posted April 29, 2014 Thanks for ur input guys, I wasn't thinking but I had 2 more trucks here with the same set up, so I went under and unplugged one on a 2012 and it ran perfect without it, so I put this one back together this morning and it fired right up and ran excellent,there's a chance it could throw a light but I can't tell right now cause I have all the O2s unplugged, but after I get it all back together ill chime back in on the light, thanks everyone for your quick response, very appreciated!

Dansilvy75 Posted April 30, 2014 Author Report Share Posted April 30, 2014 Update, got everything hooked back up and no engine light or codes, thank god lol Quote Link to comment Share on other sites More sharing options...
zippy Posted May 1, 2014 Report Share Posted May 1, 2014 When you run it without the cam sensor the engine will not run in sequential injection mode and coils are fired in waste spark mode. You could just add in the wiring and change the O.S. to run it since there was VVT back then on the 6.0L truck. If you want it to run correct you should change the cam and front cover to get rid of the VVT. Quote Link to comment Share on other sites More sharing options...
Dansilvy75 Posted May 3, 2014 Author Report Share Posted May 3, 2014 Zippy thanks for the info, I'm gonna run it after the paint work is done, get it out on the road and check it out, if it acts funny or doesn't run right I think ill do what your talking about and delete it, hopefully won't have to but no biggie if I do, I love doing extra work I didn't plan on lmao, thanks for the info tho, also I wanted to ask you something? Do you tune SS trucks, I could be wrong but I thought I saw some peeps saying you could, at least I'm pretty sure I did lol, anyway, if so I've got an 04 SS, that I might need some tuning on after it's finished, thanks again for the info!
