I just re did my timing chain and put everything back together but when i try to crank it, it wont turn over. it sounds like it wants to though.. I have already searched and i found a few topics but none were like this.
I have placed it on TDC and lined up the distributor but it just wont turn over. What do i need to do? Can you please help? Thanks

Car wont Turn over.
Re: Car wont Turn over. (trulyphly710)
When you say turn over, you mean cranking the engine by the starter correct? So you turn your key to the start position and you just hear your starter solenoid click, without the starter being able to spin the engine? Sorry i ask, some people have their own definitions for turning over.
What do you mean by it sounds like it wants to?
Have you made sure your battery is charged up?
Other than that, it sounds like your cam timing is way off. Always a fun problem to deal with.. Also, if your starter/battery is working right you might have your valves stuck out when your piston is all the way at the top. Im not really sure if that could actually stop your starter from turning the engine, but i know it can bend your valves or crack your pistons if its actually cranking.
Whenever you mess with your cam timing, make sure you take out the spark plugs and turn the crank pulley by hand to make sure that your valves arnt hitting the pistons.

Re: Car wont Turn over. (480sx)
you know the sound it makes when u start your car and then it starts? It makes all the noises but just wont start.. i dont know the right terms for this. but.. i'm beginning to think i might not have a plug or something connected.. but im not so sure.. does it mkae any sense?
Re: Car wont Turn over. (trulyphly710)
Soooo your car is going vraaraaraaraaaraaraaa(turning over) and not starting.. Your valve timing is probably off. Most likely you didnt put your cams back in the way they came out.
Befor you rip ur valve cover off again, make sure you have everything else right. You have a FSM and know how to set your distributor when its at TDC right?

Before we can help you diagnose your problem, please state the year of the car and what motor is in the car. The timing procedures vary according to what motor we're dealing with.

Re: Car wont Turn over. (rogoman)
I have a 92 240sx w/ the KA24DE. sorry about that earlier.So i should place it in TDC and adjust the cams? how do i do that?When i placed them in, it looked correct from the fsm picture.
also i noticed that the cams are color coded....... but i didnt see the color in mine.

Re: Car wont Turn over. (trulyphly710)
I have another question? the coil seems to be fine but the spark plugs are just not firing. Could it be the distributor itself or the cap? I have the "mitsubishi" distributor cap, however, i noticed that theres exact moldings for the rotor inside the cap but that moldings on the inside broke. Could this also be a reason why its not firing?
Please let me know.. If you need pictures, i can take a picture.. Thanks!!!!-Woo

Re: Car wont Turn over. (trulyphly710)
To recheck your cam timing, first disconnect the ignition coil wire, remove all the spark plugs and remove the valve cover. Have someone tap the starter while you have your thumb over the #1 spark plug hole. Once you feel compression, insure that the block timing pointer at the front pulley is pointing to the zero mark on the pulley. Remove distributor cap and insure that the rotor is pointing to #1 firing position. The #1 piston is now sitting at TDC compression stroke. The upper timing chain mating (gold) mark should be at the small idler sprocket gear mark. The other two chain mating marks should at their cam gear marks.trulyphly710 wrote:I have a 92 240sx w/ the KA24DE. sorry about that earlier.So i should place it in TDC and adjust the cams? how do i do that?When i placed them in, it looked correct from the fsm picture.

Those marks on the chain itself will rarely line up with the corresponding marks on the cam sprockets, and the idler pulley. You can however turn it over by hand until they line up(or dont, if you have your cam timing off).
You will need to take off your upper timing chain cover to do this. On the idler pulley itself there is a mark, and at TDC it will be at the bottom right hand side of the idler pulley. Its a little indentation on the idler pulley. Set the gold mark on your chain to line up with the center of this mark. Next, bolt your timing chain guides back up, so that you cant move the chain while its resting there.
After that, line up the silver marks on the chain with the little dots on your sprockets. You will need an adjustable wrench to move the cams into the correct spot, so the sprocket will go up on the cams. IMO, its easier to do it this way than to guess at what 10 o clock and 12 looks like. Plus you have the satisfaction of knowing its done right.
So you say your not getting spark? I have no idea what you mean by the moldings inside the cap are broken. Disregard the posts about your cam timing until you fix your spark issue. You are grounding the spark plugs when you are testing them right? A picture of what your talking about in regards to the cap would help.
