1990 honda accord will not start sometimes. it

get the fault codes read
indicates over fueling from excessive fuel pressure, faulty injectors, leaking injector seals

Check the starter motor. Many times they go on there own with no sign, and having someone crank it while using something to tap it often helps it turn over.

Check your battery earth and the engine earth to the bodywork if there worn the engine won't run.
good luck

if its turning over real fast it could be flooded if not u need 2 check cambelt has not striped or broken 2 check cam belt remove dizzy cap&make sure rotor is turning when motor is cranked over

Try checking the shift position switch( neutral safety switch). this prevents the car from starting while the transmission is in drive or reverse. Try starting your accord while moving the shift selector around. Also, try looking at your starter. sometimes the wires corrode, and fall off, which would make it click and not start. also, check all of your fuses,
!!GOOD LUCK!!

this sounds like a crank sensor is faulty or becoming faulty..and when you shut the car off, it take away that spark not allowing your start...however, on other times, the spark is present with a strong, crank...try testing the crank sensor, if bad, install new one...

You should be able to remove some 10 mm bolts from the timing belt cover and pry the cover out of the way enough to see the timing belt. Have an assistant crank the engine and look for movement of the belt. If you cannot get the cover off, remove the valve cover and look for movement. Don't crank the engine too long with the valve cover off, as you make make an oily mess, especially if the engine fires and starts.

other than the timing belt being broken, it sounds like the crank sensor in the distributor. get a used distributor. but first pop cap off and see if it is turning with engine.

does the engine sound like it is turning over slow? It may be the starter dragging. If it doesn't turn over fast enough it won't crank.

Your Starter is Bad. Change it out and you should be Just Fine on Starts.
