i put it on the scanner i got and its showing no codes. the scanner i got is just one from harbor freight so im not sure how reliable it is. i bought the crank sensor today and if its not raining when my dad gets off work we will put it on there.

 

i havnt let it sit and idle i only tried driving it.

 

I have a few OBD2 scanners and 1 is from harbor freight and it does do live data. It can even be used a data logger. And it was one of the cheaper $150 ones.

Hope that cures your problems! If for some reason it does not; it may be worth while to let a shop diagnose it and then you can make the repairs depending on the root cause. It may make more sense then just throwing parts at it. I don't think a shop will charge you a whole lot to figure out what is specifically failing as long as the problem can be duplicated on command which sounds like it can be.

Hang in there! I just picked up a 96 Z28 and no sooner do I get one problem fixed she throws another code for something else unrelated and of course she was rocking the rejected sticker and my 14 days are up! I knew what I was getting myself into but just funny that they are not present together but 1 after another. I am making up for years of abuse/lack of repairs. Treat her well!

I am sure everyone would like to know how it turns out so please report back.

 

crank sensor will sometimes not throw a code when failing. can cause a no start. also test your temp sensor, can on a rare ocation cause a no start.

 

is it hard to change the crank sensor on these cars? it looks like i have to take the belt off and the bottom pulley off to get to it. Is there an easier way or is that how you do it?

 

I have never personally done it on your make/model but from what I have seen it seems like that is the only way to do it. The crank bolt is usually a PITA to break it loose and your defiantly going to need a puller for the balancer. This just a guess but you will probably will need a harmonic balance puller. Most people will use a 3 jaw puller if they already have one.

 

yep gotta take the ballancer off. pretty sure you can take the three bolts out and work it lose from the hub. better look in the manual. brb

 

go here and look 99 fbody manual should do it. http://www.mediafire.com/?40mfgeoe4ctti

 

well i believe i fixed it now. i jacked the car up and went to unplug the wires going to the crank sensor and noticed the came off really easy so i pushed it back in and made sure it was connected good. i just drove it about 6 or 7 miles and it seems fine.

 

im glad i fixed it but it just sucks that something minor like that can keep me from having my car for 2 months.
