Fresh engine rebuild.. no start.. look inside!

Post by green91 »

Okay guys,
I just rebuilt the ej22t in my 93 tleg. Engine turns over etc, but will not crank.

so far:

- re-checked cam timing (t-belt)
- checked spark at all 4 plugs.
- spark plugs seem to be gas fouled.
- engine has compresssion, engine turns over much faster with each of the spark plugs removed.



So basically ive got timing, fuel, compression & spark.

Ive tried starting it with the pipe off from the turbo to throttle body and it still seems to be dumping alot of fuel. With this pipe off the MAF shouldn't read any airflow. This leads me to believe that the engine is being flooded somehow. Are there are common reasons for these engines to dump fuel?

Im very concerned about fuel washing my cylinders on a fresh build.

The strange part is that the engine ran before i removed it (was knocking, but still started easily).

Any suggestions would be helpful as im not real familiar with these cars yet!

I tried adding some oil into the cylinders to help lube the rings and build a little more compression.. when trying to start the engine now i get some smoke from the airbox. Since i know the cam timing is dead on (checked it again) this would lead me to believe that the ignition time is off somehow. This engine has a cam & crank sensors and has electronic ignition.. how could this happen?

Update:

I should be more patient before making threads with my problems LOL.

After looking at some pictures online i discovered there are two timing marks on the crank t-belt pulley, and i think i may have used the outer mark rather than the inside mark, and therefore my belt timing actually is off.

Good news!

I reinstalled the timing belt (correctly) and it started on the first hit. The engine runs great.. does have a tick so i may need to bleed the HLA but aside from that im thrilled. Thanks for your help guys!

I finally got to drive the car for the first time today (since i bought it blown up!!)

Good news is the trans and everything shifts smoothly and is very quiet.

Bad news is this car is slow as piss.
