We need a lot more information. How are you testing for spark? Compression test? Tuned?
Is this a new engine/setup or did it quite working recently?

Four basic things needed for start-up:

Air, Compression, Fuel and Spark.

More specific things needed:

Correct basic timing, correct tuning/ecu, cam and/or crank position sensors working correctly, correct engine harness ground connections, correct fuel pressure. etc etc. the list goes on.

Timing could be off.

Is it getting spark when cranking? Or just voltage at the dizzy?

^^ What these guys said.


Every time a honda wouldn't start for me it has been due to the ignitor failing in the distributor. The exception being some of my 90-93 accords and the main relay failing but that was obvious as the pump wasn't priming.

it was started 2 days ago fired up twice perfectly fine but it just stopped turning on

Tell us how you testing spark.

spark was tested with another spark plugs i had put it on the valve cover and got a good spark it didnt look weak at all ,

You steal this engine Ahmed?

Boost_em1_

did you think before u posted that ,

changing out the harness due to the fact that it wouldnt even start with starting fluid and this harness looks horrible from the previous owner

KevinEF7

But you just said it ran fine twice in your other thread... if thas the case dont change a harness for the fun of it

Why so many threads?

Boost_em1_

It ran twice with the unplugged stuff cause there is nothing to plug that stuff into but we were thinking of changing the harness to the one that came with the engine thinking that is the issue

Take pics of the timing marks at top dead center.

Air
Fuel
Spark
Timing
compression

If you have all five and its still not starting you're either lying or you don't know how to check one or more of those 5 things listed.

Is it tuned? What system if it is?

You could also be flooding the motor or the battery is dead.

Do a load test on the battery. If you been cranking it a lot it could be that. Put a volt meter on the battery and when cranking the motor observe houw much voltage is dropping. Less than 11 volts the bat needs to be recharged or replaced
