Hi, i have a 98 honda accord lx recently i had a water pump put on the car was running good for bout a month then one day i was driving in the belt came off because the pully was loose i got it fix again end up having the same problem my dad end up tightin it up so now it good.But the car wont crank it act like it wants to but it won't my dad check the spark plugs i guess its good he say it may be the pressure regulator it spray out but not how it should have if it's not that he say probably the timing because all of a sudden it turn off the same night it went out on my he got it to crank but the car was shaking someonehelp me please!!!

 

verify the timing belt is set to the proper time by checking the crank and cam timing marks line up. If the car still runs rough, then try a compression test.

 

If crankshaft pulley came off, you could have lost the woodruff key that aligns the pulley w/ the crankshaft. This would cause a loss of timing between crankshaft and camshaft and likely valve damage.

I would not turn engine over w/ starter but turn manually w/ socket on crankshaft bolt to align for timing check. Pulley will need to be removed to check for woodruff key presence.

good luck

 

The car not running though it act like it want to crank but doesnt so still see If its line up?

 

When they fix it the key was slightly in so they put it back in my dad tight in it up but just won't crank its like something stopping it

 

Need to check that crankshaft and camshaft align to TDC together.

It may be that you dodged valve damage, however if timing is good, then a compression check on all cylinders w/ starter is next step.

good luck

 

Okay will do thank you!
