I should be picking the car up to bring home on Thursday. Tell me what I need to add to my signiture and I will add it. Sorry for lack of info on that.

You make an excellent point, I do not see or smell smoke in the exhaust when the car is running. I have not noticed any oil level changes on the dip stick.

I will do the compression test pre adn post adding oil to the cylinder and record the values.

I will also make an appoinment for a second opinon.
Thank you - and I will post again once I have some more information.

 

^ The only thing I would add to the signature is... nothing. Except maybe spelling VTEC correctly, but that doesn't matter.


Desert, how much oil are you supposed to put in the cylinders? There's a big difference between a teaspoon and a quart

 

The TW sensor suggested by DH has merit. Your original description suggests massive flooding and perhaps gross liquid fuel getting into a cylinder (knock). I agree that engine wear to the point of no compression is very unlikely w/ normal maintenance on a 2001. I agree you need a better mechanic.

good luck

 

Okay - I will bringinformation (TWSensor) to the new mechanic. What is the TW Sensor and what does it do?

 

I'm stupid, I totally forgot that one of the first days that the first mechainc was working on the car he was sitting in the drivers seat cranking her over trying to start and the engine was spinning "with no compression". There was a second mechanic looking under the hood at teh same timeand they both heard a CLICK sound and the car immediatly started.

I started typing a cronological list of my issue, what was thoughtto bethe root cause and corrective actions taken. I noticed that if it is about 40 degrees or colder she will crank "with no compression" and not start. If it is about 40 degrees or warmer she starts with no issues.

Do either or both of these relate to the TW sensor?

 

A "click" and then start would suggest main fuel relay fault disabling fuel pump. This is a common failure on Hondas.

The TW sensor would not click and then start, but if faulty could cause flooding if sensor is telling ECU that engine is very cold.

good luck

 

Just for yuks, Texas, you didnt answer his question.

TW is the water-temperature sensor for the ECU. Theres actually 3 similar sensors, like this...

In the thermostat housing (LOWER radiator hose back towards firewall). Thats the fan switch, to switch the radiator fans on & off.

In the end of the head, below & forward from the distributor are 2 sensors. The smallone with 1 wire is for the dashboard temperature gauge. The larger one with 2 wires is the TW sensor whichmeasures the temperature for the ECU.

 

Thanks Jim.

 

Looks like old gas might be my root cause. The day before all this started I put 3/4 gallon of old gas in the tank with 16.25 gallons of 93 octane. (restoring a 67 Dart and didn't know what to do with the old gas).

I used 1/3 old gas 2/3 93 octane in my leaf vacuum. Leaf vacuum ran fine for 2 hours. I let it sit for a couple of hours while I ate lunch and raked by hand. Tried to start the leaf vacuum and it wouldn't start, no compression. I took out the spark plug and could see that the intake valve was not moving, but the exhaust was. I tried to move it back but it was stuck.Sprayed a little WD40 around the valve stem and valve guide then tried to move it back it it moved freely. Put the spark plug back in and it fired up on the first pull. I'm guessing that the old gas casued a gummy residue on the valve stem and made it stick.

I'm thinking that the old gas I put in the Accord is gummy up somthing , especialy when it gets cold out, making "it" stick open hence no compression.

The new machanic still hasn't looked at the car yet, hopfully end of this week or beginning of next week.

 

THE PROBLEM IS SOLVED!!
It looks like hte 'little bit' of old gas was the root casue of the issue. The new mechanic used an engine cleaning treatment on teh engine and drove the car for about 50 miles. The car started without issues the next day, but it was warm out. The car sat over the weekend and a cold front hit New England. On Monday is was about 35 degrees and the car started and the mechanic drove it all day with no issues. he let it sit outside Tuesday night and Wednesday night, both night it was onl yin the high 20's and the car started with no problems in the morning.

The old gas gummed up someting in teh engine. The colder it was, the sticker the gummness was. Whatever was gummed up casued the no compression issue. I've had the car back for 4 days and it has bee in teh 20's adn 30's and she has started every time!

Thanks to all who read and posted, and I hope this is useful to someone inteh future.
