right side of engine, no fire

'96 E-350 Van (motorhome)w/7.3 turbo, has not had any power since purchased 4 mo's ago. I had the doghouse off and was running it, I tapped the rt side exhaust tube going to the turbo and it was cool to the touch. Any opinions on a good place to start troubleshooting. It starts right up and idles, revs up in park, no power at all under load.
-thanks for any help

We need some help here. No offense - are you sure that was the exhaust? Try touching the exhaust manifolds. If one side of the engine wasn't running, you would have lots more symptoms. You could have an under-valve cover wiring harness problem. That might be whats happening. I still think you would have more problems, though. Maybe the turbocharger isn't working - kinda' what it's sounding like.

thanks for the reply big al, I am replacing the exhaust donuts going into the y pipe. it's fairly easy on a van; Ford wanted a fortune so I put it back together so I wouldn't forget how it worked, (so I could research a cheaper part). Once back together I ran it to see if any of the leaks had sealed. They didn't, but that is when I noticed the right tube comming from the manifold up to the Y pipe was cool and the left one was scalding. I wondered about the undercover wiring myself, but do not know how to check easily.
thoughts??

Try having an injector buzz test done. It will let you know if all 4 cylinders are out. If so, you probably have a harness problem. You could pull the valve cover and inspect it or use a multimeter to check for continuity, but it is usually obvious.

On the valve cover gaskets just remove the valve cover and look for any burnt connections. They should be obvious if they have shorted out.

I would be shocked to find out that these engines could run on one bank only. But these things suprise me all the time.

You have got to be throwing codes if that is the case.

thanks you guys, now if I can just lose a bunch of weight maybe I can get my arms and hands to the valve cover bolts (van joke!!) I was thinking along these same lines, with your wisdom on the subject I'll get busy.

You have to take it somewhere that has the right diagnostic computer, Like a MAC or Snap-on type. A scanner won't be able to do it.
