today i plan to change my knock sensor, after changing the knock sensor an put everything back the car wont start im getting fuel but no spark. use my obd2 scanner an keeping code p0335 crankshaft sensor A change sensor but same thing no start looking for some help here plz

 

Is your SECURITY light on?

That's the first to check on the 99

 

 

no security light on it an i tested all the sensor today but it end up to be the 10amp fuse that was blown under the hood. the only next thing is the car hesitate when u accelerate an wont drive 2500 rpm

 

That is the MAF causing that problem.

 

OP, was your car totally normal before you changed the KS and these two problems magically popped up? Doesn't add up.

+1 on MAF if you can't go above 2500rpms.

 

the car had a few problem when i bought it. i use the scan tool an the ks, multiple misfire code came up an hesitation when u drive it an wont past 2500

what i change so far

knock sensor
i change injector rail an the skipping went a way for a few only when u drive no u hear the skipping an bucking an hesitation

 

im gonna try i use MAF an let u guys kno

 

You should have prefaced that info to begin with. Chances are, you replaced the KS unnecessarily, as it's often a piggyback code to other codes. Fix the real problem, and the KS code goes away.

 

 

 

Did you remove the intake manifold to replace the KS? if so, double check that you plugged in the rear bank subharness. I know from experience that the car can start with only 1 bank working...

 

when i took out the ks it was crack on the side of it

 

change maf an still skipping an now MIL light flash when u try to give it more gas

 

Your KS could have been bad especially if it looks beat up but for future reference, when you get a KS code it usually points to another problem. Hell, my KS is still factory

 

OP test your car sensors and make sure they are all working:

 

thanks man everything is good now i change spark plug an fuel filter an other little check now everything good an no mil light
