Help needed: Boxter fails to restart after rebuild / windows no longer work

[Jamesp]

Yikes, the motor is in the car after a rebuild and it wont start! And the windows jumped ship too!

So here is what I've done so far:

Cranked the *&#^@_) out of it - it has hit once or twice, but nothing to write home about

Cranked with the Mass Airflow Sensor connected and disconnected

About fuel flow

There is gasoline smell from the exhaust and a bit of gasoline wetting a small bolt on the bottom of the right front catalytic converter.

Pulled the #3 plug and it was completely fouled with fuel.

About Spark

Checked for spark by grounding #3 plug while the engine was cranked and got seriously strong bright blue sparks.

All six coil pack connectors were numbered the numbers were matched to the cylinders on reinstallation. They only fit one way due to harness length. Each coil pack was returned to its original location.

Sooo, got fuel, and got spark in the right place.

The fuel has been in the tank about 3 years old, but does not have the sickly sweet smell of really old fuel. Anyone have experience with old fuel causing starting problems?

I was very careful on valve timing and used the lock down tools with the engine locked at TDC.

Curiously, windows no longer function after sitting unpowered for about 8 months - trying to put the window up there is nothing, no sound, no movement. trying to put it down I get a click from a relay in the door. The fuse is good. :ah:

Here is a video of the engine cranking over:

Any help or suggestions wouild be appreciated, especially on the age of the gas - I'm more than willling to / leaning towards swapping it with new, but if someone knows that is or is not the problem I'd like to hear that.

My best guess is the timing is off. Maybe try advancing or retarding it by 5 degrees or so and see what happens.

2003 Boxster 3.2. Are you referring to the valve timing? It was spot on though that is one thing I'm going to have to double check if the old gas thing doesn't work out.

I'm thinking I can empty the tank by pulling the rear pressure line and powering the tank pump with jumpers That serves the double purpose of emptying the high pressure side and the tank.

My bet is the 3 year old fuel. That's old...

I didn't realize the fuel was that old......

[Jamesp]

Complete fuel change out is the next step. That will elimnate one possible problem. If no joy there, what next? Any suggestions?

[Jake Raby]

3 year old fuel? Really.

It may be a good thing the engine hasn't fired, 3 year old fuel will varnish valve guides and seize valves in a jiffy.

Wow.

Wow.

So that's a yes on the fuel being the problem?

Definitely. Something to do with the ethanol portion of the mix that absorbs water. Many are cautious not go over 3 months on old gas.

[Jake Raby]

His problems will start with that.. If that was E10 fuel its probably already killed the fuel pump. The fuel should have been drained and the tank preserved.

Thanks for the information, if the fuel pump needs replacing, I'll know why. So, back to the original question to the old gas not firing, does anyone have experience with this? I'm leaning on the experience of the community to get the car fired up. any help in that vein would be appreciated.

Bummer. I have been looking forward to your engine running.
Have you left anything off or unconnected, like the tranny?
When I do my bearing I hope to be able to start the motor without the tranny installed. I was wondering if you are trying that.

Is it possible to see if the throttle body motor is working? When I start my Box it always starts with a little blip on the throttle ( from the ECU, not me).

Those windows are bugging me. Are all your grounding straps installed?

[healthservices]

Fuel... yeah its possible esp with as humid a Houston gets..

Although the fuel could be a problem, with it being less than 5 years old and more than 2 I kind of doubt it. but ethanol fuel in late model cars does have its issues with time. pull it out and put it in the lawn mower to test I'm sure it is probably still good for other uses.

Lately I've been resurrecting dead cars that have not been running in years. Surprisingly they all start. yea some run like crap but they all start...

[healthservices]

oh... your video does not work.

[Jamesp]

So, the tank is empty, tomorrow 5 gallons of new premium goes into the tank. I broke the fuel system at the firewall and jumped the fuel pump relay to pump nearly 15 gallons out of the tank at a 30% duty cycle. We'll soon see if it was old gas...

does not want to attempt to fire at all...

Does it even sound any different when you pull the ignition, and turn the motor?

[healthservices]

oh after you put the new fuel in but before you crank, dry your spark plugs out, and crank the motor over with the starter (with plugs out) 10 or 15 seconds to dry out the cylinders.

[healthservices]

not to be a pessimist, but your motor cranks kind of funny

[Jake Raby]

That engine has compression all over the place.. I can hear it based on the load on the starter.

Did you have the entire engine apart? Explain how you carried out cam timing.
