Default Car Fails to START, help needed!

Hello All,

I am supposedly at the end of my 93L to 00RS Conversion. Basically I have changed everything in my 93L wagon and replaced with components from an 00 RS (Driveline and engine) and 00 OBS (Interior). All is installed, torqued, and adjusted.

The problem is I cannot get the car to start. Here is what I have done so far in troubleshooting.

Here is the symptoms: Engine will turn over with Starter motor, but will not fire. There is plenty of fuel and I have checked and do get spark. Also completed a compression test and all cylinders are holding compression (Between 161 to 167 psi with cold engine). Plugs also look good.

Plugged in an OBD-II Scanner and all looks good except that RPM shows at 25mph (Engine is not running, just ignition is on) and Ignition Timing is reading -65 degrees. Car has plenty of fuel.

While trying to start the motor, I monitored the scan tool, it shows change in throttle that relates to when I push on the pedal, and RPM rises to show the engine is turning by the starter motor, but when I stop it goes back to 25 RPM.

MIL is reading off, but I am getting a P0463 Fuel level sensor High input....but that should not stop it from starting. Because I am getting this code, as well as all other sensors from the ECU, I think it has not shut down. But saying that I have noticed that it does on occasion get a "loss of communication" on the scanner at times.....so I am not sure even on that.

NOTE: This engine is KNOWN good, it came out of my 00 RS when I did the WRX conversion (I did the wiring on that too and it was much more complex then this) So it was running when I pulled it out, and it has sat in my garage since then.

Here is what I have done in T/S

1. Changed the ECU.....no change, same status on other ECU's.

2. Changed coil pack....nothing

3. Changed Main Harness. I was using an 00 Forester Manual Harness, which was cut on the Driver end (Just where it does a 90 deg turn down, (Connectors effected were B30 (Door harness), Cruise Control Module, and AirBag.......all connectors on the engine were intact, and I repaired those that were cut). Thinking I may have done something wrong, and after checking it over for 5 days with no problem found, I went and got another harness from a 99 OBS manual with 2.2L. I did the needed changes and adds to make it compatible with the 2.5L motor (I have the wiring diagram manuals), and after all this, there is no change in symptoms, so the wiring looks to be good as far as I can see, or not see.

4. Flipped the pos/neg on the crank sensor to see if it may be reversed, No fix, infact it stopped showing a change in RPM when I tried using the starter motor....stayed at 25 RPM. Also played with the cam sensor with no change.

SO.......basically this is where I am at. Everything electrically on the car works, (Windows, lights, radio, A/C, starter motor...ect) BUT the engine will not fire.

I have fuel, spark, compression, and air......but ignition timing shows a negative 65 degrees.

I am at a loss of what could be the cause, so I am asking for your help in this......I am out of ideas.

PLEASE HELP!

Thanks

EddyL.

Hi:
This is a strech, and I do not want to insult you. But is it possable that you have the spark plug wires crossed and are firing on the exhaust rather than the compression stroke?

That made me laugh.........NO there's no way I can screw that up.,

1. The coil is marked 1,2,3,4, as is the plug wires. Also when I pulled the engine, I did so intact, so nothing was changed. Everythings going where it should.....It's just not doing anything.

Thanks for your input......but that is not the problem.

Any other input.......even outlandish

I'm thinking that too. I did do a continuity check on the wire from the ECU to the Crank Sensor, it was correct. I plan on doing resistance checks tomorrow. I also will check the Cam Sensor and the Knock sensor while I'm doing such.

Unfortunatly it's a holiday tomorrow, so i won't be able to get a sensor if it's bad. Though I can't see why a sensor would go bad with the engine just sitting for a little over a year. Seems strange to me.....but I am running out of options as to the cause of the failure.

I'm just hoping someone has experienced a simular problem and knows what may be the cause of such.......got to hope.

Wow, done already!

Anyhow, Check the engine temp sensor. Im having that same problem and saw a thread here on nasioc in the service forum about someone with an older L having starting problems where the engine wont start but the starter is going and it was the engine temp sensor.

Great News.....

I finally got the blasted thing to start. Was a combination of things, but the thing runs. Well except that I now have a failed O2 Sensor.....looks like all that unburned gas being dumped into the exhaust did alot of harm to the sensor.

Now that I got the car running, I took it for a shake down run.....all seems good except I am getting a whirring noise from the back.....sounds kind of like the same sound as hearing big off road tires at high speed (It does increase as the car goes faster, no vibration or such....just the noise.......I'm not sure what it may be, but it has to be one of the following

1. Propeller shaft not aligned right....checked and do not see any binding...it seems to turn freely.
2. Alignmend of rear end.....not sure. I went and set the rear to the same as my RS.
3. Rear diff possibly gone bad?
4. Wheel Bearing?
Checked the E-brake and even loosened it so that it cannot clamp and noise still there.

Oh well....at least the cars running......

Cheers
