ive tried everything..ive tried adjusting the sensor..ive taking off the valve cover and put number 4 piston at tdc and aligned the camshaft sensor again and still nothing..anyone have an idea?

 

damn ur having allot of problems lately eh?

 

cuz i just got my car back after a complete overhaul

no one can help?

 

ask wsfrazier or witt.

 

make sure cylinder 4 is TDC on the compression stroke.....line the mark on the sensor housing the the hex shaft.

There should be alignment marks on the crank damper and front cover if you're having an issue also

 

the build book says cylinder 1...i did number 4 and is the mark on the sensor housing look like a mark put into it

 

you get that **** fixed yet?

 

not yet dude...

 

you probably need to do a reflash or a crank case relearn.

 

i cant do a crankcase relearn until all codes are cleared....

 

Will it not work with Cylinder 1 at TDC?

 

a cute picture...

 

What codes are you getting?

 

everyone is saying cylinder 4 at tdc of compression...build says number 1..they are at tdc together but when 4 is on compression 1 is on exhaust

p0101 maf performance
p0017 camshaft correlation code
p0315 crankcase relearn

 

Well cant hurt to try it again with the crank spun another 360*. Get 1 to TDC and try it out. Typically #1 cyl is the standard for setting an engine.

The camshaft rotates at half the speed of the crank so that could be why it isn't working with 4 @ TDC.

Those other codes like you said you can deal with after.

 

tearing apart the valve cover and lining it up is ftl in 90* weather lol..i dont have reverse in my car right now so i cant pull in my garage cuz my driveway is a hill

 

Call out the crew! Make em push! HAHA!

I am guessing that is the problem, the cam sensor is likely 180* off.
I am not an ecotec expert, but i have worked on other engines!

 

yea it might be...will see

 

yes, cyl. 1 and 4 would be at TDC at the same time.....just on different strokes. You need to have cyl 4 at TDC on the compression stroke, which should put cyl. 1 TDC on the exhaust stroke.

 

have you tried disabling those codes and then running a case learn? idk if it will work, but worth a try imo.

 

disabling the code doest clear them..just causes the cel not to pop on the dash..so when they plug in the tech 2 its still there...

 

damn.....

 

we got another car doing this right now, anyword on the fix? did a case relearn and the CEL hasn't popped back up, but the car is still a pita to get it to start.

 

How did you put the camshaft sensor in???

 

yeah my car is doing it right now after we redid the pistons and i cant get it to relearn itself help :/
