91 honda crx suddenly would not start

You have leaking spark plug grommet/seals under the valve cover, and most likely being a 91, also have leaking cam tower o-rings. The first is just a matter of replacing the valve cover gasket set. The second requires removal of the cam tower/rocker arm shaft assy. to access the o-ring seals between them and the head. If you are not an experience mechanic, I do not recommend doing this yourself. It is easy to damage parts and bend valves if you don't seat it properly.

I think you need a tune up spark plugs and plug wires distributor cap and distributor rotor

if no fuel pressure or spark its probaly the "Main Relay" this is located under the steering column. hope this helps.

POSSIBLE distributor cap and rotor spark plug wires

is there water in oil or oil in coolant?those cars have bad rep for heads and head gaskets blowing....
sounds like head gasket blew, water sucked into cyl.
check spark plug if might have wet contact from water in cyl.

no, not a blown headgasket, remove the valve cover and inspect the spark plug hole seals(tube seals in the valve cover) replace if brittle and old. also change the valve cover gasket since u have it off...adjust the valves as well

Yes the oil can cause the car to lose spark, the oil leak could be caused by the valve cover gaskets around the spark openings, but 9 times out of 10 it is the spark plug tube "O" rings. The top of the valve train comes off of the head, the "O" rings are between the two halves, that will fix the oil leak.

ok.....as far as the oil on them it is possible it is only the spark plug tube seals located on the inside of the valve cover,in fact if you can remember when you took the old plug wires off the boots of a couple propably had oil on them.now as far as the real problem I would recommend checking the timing belt it is possible it jumped time,its pretty simple just remove the valve cover(gonna replace the seals anyways)and top timing cover.roll the engine around and look for the cam and crank marks.if you need anymore suggestions or help let me know have a good day DB

Take the car to a car wash and power wash the engine. Do this ONLY with a cold engine. And be prepared to have problems with it starting as water get's into the electrical components. Take some WD-40 with you to spray inside distributor caps, on spark wiring, etc. to get the engine running again.

Then check the engine weekly to see where the oil is coming from.

did you try changing you sparkplug wires?


hopefully that fixes it.
