98 passport, 3.2 v6 4x4.
The engine is running on 3 cylinders, the three on the drivers side have no spark.

All cylinders have fuel.

Have swapped coils from side to side with no change, so its not a coil or plug problem. All six plugs and coils fire on cylinders 1,3, and 5.

The hot wire to the coil has power, just not to the signal.

The only cel i'm getting is p0121 for throttle position sensor, I'm thinking this is totaly unrelated besides the fact of a bad ecu.

All help is greatly appreciated.

 

Have spark now, all six cylinders have fuel and spark, but is still only running off the passenger side cylinders.

Some one please help me.

Still have p0121 after checking the wires and replacing the tps.

 

try replacing the tps anyway. a real bad one can do that. and i dont remember if these have an ICM but i might look into that.

 

I did replace the tips. But i noticed the intake manifold was missing a bolt think
It might have blown the gasket since it is on the same side the problem is. Got a head gasket kit and plan on checking and restoring the top end.

 

ahhh damn. good luck man. let us know how it goes. btw, is your name the song from the band In Flames?

 

lol officially hate this car. could not get the exhaust manifolds off, seems to be welded and can't get a breaker bar into position. But the intake manifold had a pool of oil inside it. Going to run a compression test to try and verify any blown gasket before i take it to a shop. Also am planning on checking wiring and timing. The insides of the heads show signs of the previous owners never changing the oil. FML

And yes from the band In Flames, great band.

 

Spark plugs in vehicles are always play important role but at times it fails

 

Found the cause. It was a sheared pin on the exhaust cam. This caused the cam to rotate inside the gear out of time. Now just have to get gear off and fix the pin, but did finally get it to run on all 6.

 

Fixed... Put a new exhaust cam in it and it is running great.
