Be fore performing the check I will describe below do a compression check on the engine if the compression is very low (below70 psi or worse at 0) the mechanical timing could be off 180 degrees. You must recheck the mechanical timing, do this by removing the spark plugs and turning the engine over ( in the correct rotational direction ) using a socket wrench on the crankshaft pulley, you must also take the valve cover off to observe the number one piston's intake valves as they move closed, pstop turning motor and proceed to insert a straw into the spark plug hole and the continue to turn the engine until the straw moves up, when it stops moving the engine is in the number 1 top dead center firing stroke, you must now observe the timing mark on the crank pulley it line up with the timing pointer on the front of the case it should point to zero. I f it does that part is ok however you may have the timing mark on the cam shaft sprockets of check the as well. Sometime when a timing belt is done it can be confusing and the belt can be installed 180 degress off or one or both cam spockets can be off one tooth.

If timing chain breaks,will the car get fire?


If the timing chain breaks, the engine will stop immediatly, but there is no risk of fire. The main problem with this situation is that, if one of the valves fluctuate, it might impact with the cylinder head and make a big problem, a costly one. You'd have to open the engine to look at the cylinder head to see if it suffered any kind of damage. My suggestion is that you replace the timing chain before something like this happens and you get a bigger headache.

Running on two cylinders


The removal of # 3 & # 4 tells you those cylinders are
contributing the most ,as removing the wire causes the motor
to stop
My guess is that the other cyl #1 & #2 are not firing at all, if there
is no change

If you had a V6 or V8 it would continue to run,not so with only
4 cylinder

Learn or study the ignition system & replace any ignition control
module that fires the first two cylinders

Get an HEI Test Spark Plug & put the plug wire to that & ground it
& see if you get spark,check all the plug wires one at a time.

Don't forget timing belts that are worn & slip,battery voltage,alternator output & A/C Ripple coming out of it

I would check compression or better yet, do a cylinder leak down test.
Could be you have worn valves in #1 & #2 thus little spark
Check fuel pressure at motor with a gauge

Prob with honda prealude runs when it wants to will start fine one min then u turn it off and it wont start seems like no fire to cioil


what engine?
fails hot engine, or cold engine and what engine of the many?
seems dont work in repairs.
ever do a tuneup ever?
sinces it sometimes runs we can check off bad engine. of the 4.
here they are. NO STARTS:
1: loss of 12vdc electric power to the EFI system. (dash lights dim?)
2: bad engine (skip this)
3: bad spark , seems is not an option here, we test all spark at all cylinders using a good new test spark plug.
Its a honda, and we check timing, too,, using , a timing light.
if the spark is good and timing is bad, then the timing belt slipped
if it slips more, the valve in the head bend. end of motor.
sometimes no starts, saves the engine, from itself. so i do spark 100% or better, on all honda's, i do a cylinder leak down test by hand
so i dont MAKE IT WORSE. (it's and interference engine)
4: bad fueling, flooding or starvation, readling spark plug tips tells me
which it is.

3.0L & 3.2L is Non-Interference , no engine stated. so ....

Car not firing


Most likely the valves were bent.
When you attempt to start the motor does it turns over a bit fast and will not sound quit right - Not even attempt to spark up or fire up.
Check engine cylinder compression. The valves were bent when the belt broke.
you will
1. check compression (and when it fails)
2. decide to have the head checked and if possible rebuilt (use new head bolts)
or
3. Look for and buy a low milage used motor
or
4. Look for a rebuilt head

Car will not start.Engine turns over but spark plugs willnot fire


I would say replace ignition coil, that might me the problem, otherwise it can be the ecu, which might have some electrical problems not allowing the car to stay running. Good luck.

My car is not firing right,


when your engine breaks a timing belt it bends one or more valves in the engine cylinder head, that is the problem, u have bent valves.
