Video.........can you tell me what's wrong?

[sixgunsam]

My buddy just e-mailed me this video of his truck trying to start, his symptoms yesterday............... ran rough on start-up, blowing white smoke until it warmed up, cleaned up and it ran fine for 50 miles. Parked it for a couple of hours, started, smoked heavily, running rough, then died. Hasn't been able to get it fired since then.
No codes, using a Innova 3100.......
Changed CPS, wasn't it.
Fuel in the bowl, filter is clean.

Have him watch this video and have compare the exhaust manifolds for even heat.

He replaced his IDM 4 months ago...........what are the chances that it went out again?

[NoRalPh]

No, it's not about the IDM, it's about those connections at the Valve Cover (UVCH)

[sixgunsam]

Yeah.....he has already done the VC clips......that's not the problem.

I would think that the injectors are getting fuel because of the smoke.
seems like it is more of a heat in the cyls. issue.

has anyone diagnosed the gp system?

other than that, I would say to have a compression test done.

Compression test as in the motor may be dying??......The truck has ran great until 2 days ago.........

I guess im not suggesting that it is dying.

You stated that the idm was replaced, the cps, and the uvch's have been addressed. I believe it is electrical but you have narrowed down a few of the common issues.

I asked about the glow plug system first and just suggested a comp test to help identify or rule out options.

On a side note, why did you skip over the gp question?
That, i felt, was a more important question.
no big deal though.

Yea, that's an excellent point, where's all that fuel coming from...

But it doesn't seem to be running on all 8 either,,, did the SES light come on when it was doing that? I'm not sure, but I don't think your Innova 3100 is up to the task here. I'd want to see what the right scanner pulled for Fuel & ICP pressure along with the IPR % when it was cranking over now.

Both times it did it, it was after sitting? Then, once he did get it running, it cleared-up and ran well for some time... How about a bad injector dumping a ton of fuel into a cylinder as it sat maybe???
