CRX issue

[Pfreaky]

Hey here is a video of what is wrong with my crx:

I have the main relay ready to be removed, my other thought is the ignition switch.

Any other ideas.

[snm95ls]

Uh...

That cranking sounds awfully uneven.

Pull the distributor cap off, and make sure the screw for the rotor didn't back itself out.

EDIT:

The only other thing that comes to mind would be maybe the mechanical timing jumped. Hopefully that is not the case. A quick and easy check for that would be to disconnect the electrical connectors for the distributor and crank it over. It should have nice even sound to it without and kind of kickback.

:???:

Here is a vid of the dizzy

That distributor looks like it has seen better days. :lol:

Well, it looked like the screw for the rotor was still there. The rusty screw on the coil really isn't a big deal as long as it is tight, and there isn't corrosion between the terminal on the wire and the coil itself.

Well that is a good thing, kind of. Sounds like it is low on compression, but that may be from all the cranking with basically no combustion to burn up the fuel so the cylinders are washed down a bit.

Definitely something going on with the ignition sequence for some reason.

Dunno, man. There are so many variables.

I would say double check the firing order, but that doesn't change just going down the road unless you guys have messed with the spark plug wires from the time it died to the time of the first video.

Definitely not firing order. So my overall guess is main relay or distributor.

[snm95ls]

Put it all back together, reset the ECU again, and then crank it over again. See if there are any codes stored in the ECU. Look though the little window in the ECU, and a little red LED will flash the codes if there are any.

Report back.

Definitely not a typical main relay symptom.

Ok, so no codes. Just a blip when i flip the key to on position and when I flip it to accesory. My TPS has been quirky for a while now and I have recieved codes for it previously.

Edit: TPS= Throttle Position Sensor

[Pfreaky]

Also, just unplugged the TPS and the ECU didn't pick up that it was missing. And I know that the engine will run without the sensor, and I also know that when the sensor is out it will throw a code 7 at me.

Bad ECU maybe?

[snm95ls]

Interesting...

It's possible man.

Ill replace it and see what happens, they are cheap enough

When you can find one, yes.

[Turboed4]

pull the plugs and clear the cylinders them put new plugs in and try to start it sound like its trying to fire but the kick back thats it doing could be caused by improper spark at the wrong time

[grunt2001]

Thats what my aunts civic sounded like.turned out there was no compression in 2 and 4 do a compression test bro:cheers:

Did you follow the whole thread?

I will try this, I am picking up a pair of ecu's actually to see if the ECU has gone bad. I have had one go bad in this car before, but not this engine.

you should be able to look at your capacitors to see if they are leaking or at your board to see if it has a burn spot

I may or may not have............

[Dester223]

I'd try a good distributor.

OBD0 == no such thing.

Sounds like too much timing.... I don't know enough about Honda Ignitions to tell you why.

I is pretty much physically impossible to have too much timing unless the camshaft is physically out of sync with the crankshaft or is the retaionship between the distributor drive and rots have been shifted. The latter is not too likely.

There is a finite amount of adjustment on these engines via slots in the distributor mounting tabs.

You can either be 180 degrees out, and that takes some work to accomplish, or you are out by maybe +/- 10 degrees or so from 16 degrees BTDC.

Is timing electronically advanced by the ECU? Or are the vacuum/rpm/whatever advanced?

I would hope his cam timing hasn't jumped... You can hear the starter trying to fight to compress an expanding charge of air and fuel. If the timing belt skipped a tooth forward on the intake cam, that would advance timing as well as close the intake valve sooner, putting less air volume in the cylinders (Assuming the valves aren't popped). That would correspond to why it sounds like it's freewheeling on the third video (Bent valves might as well).

[snm95ls]

Ignition timing control is 100% electronically controlled by the ECU.

I just attributed the fast cranking speed in the 3rd video to washed down cylinders from all of the previous cranking attempts.

I agree that the firing events are out of sync for some reason, and it sounds just like when the firing order is wrong on these things to me, but that just doesn't happen driving don the road.

I also hope the cam timing hasn't jumped. It certainly wouldn't hurt to double check it.

It is kind of hard to e-diag this since there are many different little things to look at, and trying to explain everything to someone who isn't intimately familiar with what to look for is quite laborious.

I'm gonna pull that side cover off and check out the timing belt, I will also take photos. If It has jumped, then I will pull the head. For christs sake I was driving it nice when it did this shit.

if you where driving it nice it will be nice to you no need to pull a head when a belt is cheaper try that firts if it is out of time.

Well, ya thats kinda the plan, then if that doesn't work, off comes the head to see if valves are bent.

[jdmjames]

i was thinking the timing belt might have jumped acouple teeth??? just a thought to check befor you pull the head!

[bks84]

You can do a compression or leak down to help determine if it jumped time...

this thing for sale?
