98 Civic/d16y7 manual - not starting, pump primes, but no spark
I've cleaned IAC, changed the Dizzy(but i returned it) after i found out thats not the problem.
Any suggestions?
I hear priming from fuelpump and the main relay makes 3 clicks..

Re: d16y7 manual not starting..
1. Does the motor have spark? pull the plugs and ground them, have assistant turn the key and watch for the arc
2. Does the motor have fuel? Sounds like your fuel pump is working at least pumping. The fuel pressure could be a cause but then I would first check compression.
3. Does the motor have compression? Put a gauge on on it and report the cylinder pressures. Wasting your own time skipping this step.

Yes It cranks.
I've changed the main relay just now, and its the same.
and i hear the fuel pump prime.
and Yesterday i cleaned up the IAC, and it was dirty.
I thought that cleaning that might let it sit and run if it starts up.
1. No, i've even put a screw driver in it and grounded it and it didnt make any spark.
2. Yes, its been sitting for 3-4 days. other than that no.
I have no idea how to check the fuel pressure, but I can search it if no one gives me a guide.
3. I can check that. I guess.

Re: d16y7 manual not starting..
For compression test you need a compression tester, do an ohms test on the dizzy coil, and check all fuses/grounds, did this just happen one day? Buy it like that?

Re: d16y7 manual not starting..
And i got a question, can i check the 10p connector on the distributor, but not the male part, the female part.
I want to know where that goes so i can follow that up.. because what ever it is.. Its not working before the dizzy. Thats what im thinking.

Re: d16y7 manual not starting..
^ sorry
I usually dont read full paragraphs. ive had this issue since i can remember lol.
Ok Is Crank postion sensor connected? Broken,Wires cut? etc... any visual problems.
(you can locate this sensor right above the harmonic balancer pulley.

Re: d16y7 manual not starting..
And should i test it with a ohm meter?
like this picture has:
Is this CPS right beside my Starter? and like close to the left of my dizzy?

No it's on the drivers side were all the pullies meet, and you just need a test light and and stick it in each port while someone cranks the motor

Re: d16y7 manual not starting..
Mehran,
Ditch the compression check, no need since you have no spark.
When I first got my Honda my distributor was dead. To absolute check I took the dizzy out and bolted "through the lower bolt hole of the distributor" into the upper bolt hole. This is such that I could manually spin the distrib with my fingers.
Key in the run position. This allows for listening to the injectors fire and spark. One caveat the grounding wire from the power steering pump to the body ground near the AC condenser needed hooked up. It is possible that a 'new' distributor can be a bad distributor. When I paid for my new dizzy it cost $160 plus core $90. That hurt but the new one worked for me.
When you try this move testing the dizzy can you hear the injectors spitting and still no spark. No need for a screwdriver grounding, good way to get zapped. The plugs will be very obvious when they fire.

Well, Today when i went to check on it, i decided to take my spark plugs out, and it was filled with gas. So, what i did was I dried them, and let the air filter open and let the spark plugs out for the night till it evaporates. I hope i did the right thing.
Then, What i don't get is, I checked the dizzy and power is not going to the dizzy. what can be the problem?
So if its not these.
1. dizzy
2. main relay
3. fuel pump
Can it be:
1. ECM/PCM
2. integrated control unit behind the fuse box.
The reason why i am saying that its one of these is because my fuse 31 isnt giving any voltage from either side tabs. and I have no idea if its the number 1 or 2. (didnt want to type them out again).
If anyone helps, I'd appreciate it.
and I am going to check the G101 wire, tmorrow.

Re: d16y7 manual not starting..
Sorry for the delay in response.
You say you had the plugs out and the cylinders were filled with fuel? Tell me more about this. Was there so much fuel it 'sprayed' out the cylinders when cranking? Well there's your problem. Kidding aside, raw fuel flows down the rings into the oil, keep an oil change in mind in the next few miles.
IF the raw fuel is cleared did you try hooking up your distributor such that the camshaft/dizzy was accessible and give a finger spin? Did the plugs fire or the injectors do their injection voice?
Still you must differentiate between spark or fuel, or you just get everybody's guesses. From what you wrote it sounds like you have injectors holding open dumping in fuel.
Test the distributor like mentioned above in my other post. Another means of testing spark use a timing light. Hook it up to any plug wire and watch the blue light flash when you crank on the motor.
It can be the ecu/pcm or lots of thing yet. Might be this, might be that (bent valves, warped head, camshaft key broke, mouse ate a wire somewhere) ... Put a halt to try this try that. What do you know about the car, example owned three years all of a sudden it just died?
How did you check if power was getting to the distributor? One point I can think is the distributor must be grounded ie: one of the wires in the plug in needs grounded before the ecu will send power to the distributor. Then too many possibilities to bother before getting aboard that train.
Cheap man's way and cost nothing distributor test. See my above post with respect to testing the distributor. It only cost one 12mm wrench, two bolts (holding the distributor) and four spark plugs if you don't have a spark plug wrench. This way also tests if the injectors are clicking (firing away).

Re: d16y7 manual not starting..
He already did the test. He already checked everything. It's obvious that it's ECU. He flooded fuel inside cylinders because he kept cranking without spark. So, fuel pump kept pumping fuel into the chamber. Replace ECU and it'll be good to go.
