Accord crank no start after timing belt snapped and replaced (Video)

[pcmdjason]

Also.. I don’t know if this means anything but the oil light is flashing during crank. Like on for 1/2 second and off for 1/2 second.

No, I’ve got spark so I didn’t reference that video, but I did realize something I did wrong. I had set TDC on what I thought was #1 cylinder, but turns out it was #4. It fires 1342 so I’m hoping that the only thing wrong is it is 180 degrees off where th

Man, I hate to tell you this, but I have a feeling you have some bent valves.

Also while I’m at it where does the Accord get its signal to fire the ignition coil? I’m wondering if somehow I had the timing marks right but somehow it’s firing wrong. I dunno.

Did you check out Eric’s no start video’s?_x000D_

You will need to find a wiring diagram to see how the coil will fire. Most are timed with the cam/crank sensors.

You mentioned that the t/belt broke while driving. possible that valves were bent. a compression and leak down test will answer that .

I would also recommend a cylinder leak down test._x000D_

I always recommend once you are at TDC, rotating the crank by hand 2 revolutions to make sure the timing marks line up before starting the motor on any timing belt or timing chain replacement._x000D_

I’d recheck your timing marks as it sounds like you’re not getting compression.

[pcmdjason]

Got the compression tool but I’m at work so that’s a evening thing. Something seems to be to be binding around 1 and 4 TDC and then makes a pop. I dropped a magnet tool down the bores and am pulling up fine magnetic grit. Not looking good._x000D_

You can’t really ‘eyeball’ valve lash you’re better off checking it but I can’t see how that changed during a timing belt change however it might be an indication

Zero compression all cylinders. I took the rocker rack off which I think should have closed all the valves, rotated the engine to #1 TDC and put the compression gauge on #2 which should have been at BDC

[EricTheCarGuy]

I don’t often see valves bent on all cylinders when a belt breaks so I don’t think it’s likely you have bent valves on all cylinders.

[pcmdjason]

I did try clear flood when I first cranked it. I removed the plugs and let it “air out” over night to remove any gas in the cylinders before trying the next day._x000D_
When I did the compression test I pulled the ECU fuse under the dash which should

[EricTheCarGuy]

I don’t believe removing the head would be necessary.
