Well new ecu in did a relearn and car will still not run

 

So today going to try a main wiring harness then from there kinda lost. So far replaced crank sensor/cam sensor/new ecu/wiring to crank sensor. So today after putting in a new main wiring harness for the engine bay well see what happens

 

good luck man, i hate electrical gremlins

 

it wont crank over? Check the fuses on the inside of your car. it sounds like it could be a bad ignition switch at the key not the place where you put the key but the little tiny box connected to re: the part that's getting the recall

 

check at the ecm for wire that comes from the ignition to the ecm that tells it to start the car. I don't have my wiring diagram with me so I couldn't tell you which one that is.

see if you can find some one with a tech 2 and plug that in to your car

Better then just guessing and replacing parts

 

It'll crank over but it won't idle correctly

The new ecu does need to do a relearn to set idle and drivabilty. There is some post on here how to do it.
basically let it warm up then take it for a drive ( not to rough on it no wot ) the park it turn off wait 30 sec start it let it run till the fan cycles. turn of. I think that's it

 

You cant even drive the car at all itll idle like it has a huge cam soon as you give it gas itll die. Its been at the dealership for 2 days still nothing im just gonna tell them to forget it and burn the car

 

buddy just had the same issue. he put a new crank sensor in and still had issues. gm put in new cam phaser and fixed his fuse box because a ton of wires corroded out at 50k miles.... the car runs great now

 

my fuse box is good we pulled it completely apart and fixed bent pins no wires are showing or anything. Are you saying his whole fuse box was replaced or just the wiring. Also which cam phaser did they replace since there is 2 of them

 

both actually. they put a new box in first then found that the wires were bad down in the harness. they said its very common

 

**** if only we knew what harness. I replaced the main engine bay harness on the car that goes to the motor so im wondering if its just a bad fuse box

 

I have heard on a rare occasion of a fuse box corroding internally but usually only on cars with other issues.

 

That really sucks, i'd still buy it like it is if we can agree on price, dont burn it let me have it lol

The dealership thinks they found what it is so this could be some good news...Soon as its fixed gonna give her a gold ol wash and wax and put it up for sale again and get in contact with you

 

What do they think the problem is ? And what is the fix ?

 

Well i now feel like a complete idiot i was sitting around thinking about what could have caused this then zzp emailed me saying its a highly unlikely chance a cam reluctor might of spun but it would throw a p0016 or p0017 code soon as i saw p0016 it clicked in my head i had that code pop up one time when my hpfp stopped working so now i gotta dig into the cams and see if one of the reluctors spun. Hopefully this is the case and its a easy fix

 

I had a car today that would not start all the time. Turned out the main ground cable from the transmission to the frame was not anchored well. The nut was hard tight on the stud ( its directly under the headlight assembly on the frame rail) but the eyelet was loose. The stud broke when i tried to remove the nut so I had to make a new ground connection with a riv nut right beside it.

some of the symptoms from a bad ground include: Air bag sensor fault; occasional dash going haywire with power steering notifications on the IP etc.; car wont start; car will start with jumper cables but then wont restart; headlights not on all the time on one side.

and so on. bad grounds are difficult.
also, the conical nut was lost on the battery connector and a 6x1.00 mm plain nut used instead. That wont work; the cone in the oem nut spreads the seat to tighten the battery post clamp.

 

I did have my transmission replaced by a dealer maybe ill have to look into that ground. Im guessing the ground is on the drivers side headlight area then since thats closests to the transmission

Thanks for the idea

 

John said it was directly under the headlight on the frame rail hopefully you get the issue figured out and the car running again.

 

I was just making sure ahaha dont want to start something else and mess things up. Im gonna see what the dealer says tomorrow then tell them forget it and try the ground and see what zzp says about the p0016 code

 

I'm having the same exact issues on my 2010 LNF and I just had lifters and valve springs installed.

 

It's not possible to mix up the cam phaser connectors, is it?

 

No the plugs are actually different. However, if you installed the actuators backwards and plugged them in backwards it would physically work (I think the actuators interchange, not 100% sure as far as bolting to the head) but would be way off from a tuning standpoint.
