Hi im new here.  the other day my 2000 chevy tracker with a 2.0 died when i was driving it.  The ses light oil light and batterie light are all lite up.  It also shows code p0340 whitch is the camshaft psition sensor whitch i have replaced it still will not star and still shows that cod even after it has been cleared.  Can any one help me???

any one???

I got nuthin.

Does the engine turn over when you turn the key?

Yes it dose turn over

Did you just fuel up when it happened? Also you should get a spark tester to check for spark and a noid light to make sure there is a signal going to the injecters.

i just put p235 bfg mud t/as on my 99 tracker they dont rub its on a 15"x8" tou should be ok mind you my u joints are going as we speak theyve been on for about a month

Did you scribe an alignment mark on the flange of the CMP sensor housing and the cylinder head before removing so the new CMP got aligned during the install in the same position?  Offset drive properly engaged?

What he siad ^.

sorry man you really lost me there come again???

Just got back on the forum... well the FSM refers to scribing a mark on the original CMP and the head.   Then when you install the new CMP, you install the new o-ring, lube the CMP sensor o-ring, align the off-set coupling, install the CMP sensor bolt, but do not tighten until you have rotated the CMP sensor housing to align with the scribe mark  (there is an adjustment slot on the CMP).  Tighten the bolt to 11lbs.  Connect the electrical connector and then after the install, check the timing with a timing light. 

comon prob. pull the cam sensor conector off and check for corrison.

Sorry it took so long to reply we went to the chevy dealer and they worked on it for a half hour broken timming chain and the valves hit the pistons.  The tracker has been siting since my first post and I am tiered of it sitting.  I cant sell it because im still paying on it. So what are my opions can it be rebilt? should i start looking in the junk yard?  if i look in the junk yard or rebeild how can i make sure this dosent happen again?  I also have a chevy s10 blazer with a roten fram that runs great how hard would it be to swap in the 4.3?

The best way to prevent timing chain failure is to use fully synthetic 5W30 oil.  This seems to avoid failure of the chain tensioners.

Yes the engine can PROBABLY be repaired.  You didn't mention how many miles was on your truck but I'll guess around 130-140K.  The reason this is relevant is simply the fact you still owe on your truck AND the repairs at a shop would probably run around $1500 - $2000.  They would have to at least pull the head and machine it, pull the pan to clean out the debree from the tensioners and the clean the oil pick-up screen.  If the pistons are dicked up then the cost goes up... but you get new bearings, rings, pistons and a bore job (probably). They could replace the water pump while it's all in pieces as well.  When all is said and done, you will have a good running truck with a mint head and timing chain but with rod and main bearings with 130-140K on them.  If you go this route, you will be paying on it longer, but at least you would be able to drive what you are paying on.  You might find another 2 Liter engine available for around the same price, however you would have no idea of how well it was maintained by the prior owner.  There is a company that imports used engines (JDM?) from Japan.  Japan has some kind of rule in place where vehicle engines have to be replaced after so many miles (really low miles) like 60K or so.  These would be another option for you.  I wouldn't be too concerned with a low mileage 2 Liter.  A slightly more expensive option would be to take it to a garage that offers rebuilt engine by a well established company like Jasper Engines.  Probably coist you around 5K but you would have an entire  long block engine with a warranty and you would be basically starting from scratch.  All you would have to do is maintain it properly for a couple hundred thousand relatively repair free miles.  In just about all cases, you would have to accept the fact you would have to drive it until it fell apart to recoupe most of your investment in your truck.  Not that anyone ever regains money invested in their vehicles.  They are all liabilities.  Necessary liabilities.  Not too bad of an idea anyway with a weak economy anyway.  they are great little trucks, if maintained.
