Great video! I have the same engine. Changed the fuel pump and the crank sensor and the oil and cleaned the VVT solenoid, MAF sensor and installed new air cleaner. I am experiencing delayed start long crank after hot soak on occasion. Maybe one in five starts. When it finally starts it chugs like it's been flooded. I have a new VVT and cam sensor on the way. Can a faulty or clogged VVT cause incorrect timing at start up and delayed start? 185k on the engine btw. Thanks for any feedback you can offer.
Hey Larry, looks like you have a lot of new parts on yours! I would look at fuel first. Do you have access to a fuel pressure gauge? I would monitor fuel pressure after the trucks been shut off. It should hold pretty steady, if it doesn't, fuel is going somewhere. Sounds like you may have a leaky injector! Mike Becker, Technical Services Instructor
You bet, thanks for watching and for the great comment. Need anything related to vehicle electronics, let me know, Mark Hicks Wells Vehicle Electronics
Thank you! I am hoping to someday do another VCT class. One that actually has an engine on a stand in front of us. Is that something that you would want to see? Mike Becker, Technical Services Instructor
It wasn't really noise, we were looking at everything on that fuse at the same time. Computer computations, injectors and coils. Using an amp clamp like that can save a lot of diagnostic time. You know what i mean. Like when a customer says "How much is it going to cost to diagnose the problem". Mark Hicks Wells Vehicle Electronics
Yeah, I know it ain't really noise and that it's everything that's on the fuse. I call it noise cause I'm just so picky about how I want waveforms to look, lol.
dmorley100 Well then we are two peas in a pod! Nothing wrong with being picky! take care my friend, BTW we will be soon announcing Live webcast training you might find interesting stay tuned, Mark Hicks Wells Vehicle Electronics
my problem is moving the power steering a little to get the shaft out hopefully the 2 bolts neer the pully is the only 2 needed to remove so it could atleast move back a little.
i rather wait 2 more days when the shaft comes so i can just replace it. im also going to replace the throttle body as the rpm meter keeps hiking up high when moving from drive to park. and when turning the ac on. i will get back to you after im done.
He needs a little work on the speaking and performance, but I loved the video overall. Walking through a problem like that is the best I have seen so far
+coastalman454545 Thanks, glad you liked it. We also do our best to show the problem as in depth as possible, so when other guys run into the same problem they know how to fix it and why it broke in the first place. Mike Becker, Technical Service Instructor
great video Mark nice to see you back... VVT system most of the time is dirty oil cause the problem..
so what was the root cause of the clogged screen in the solenoid? where did the debris come from?
Hey Blkthunderbolt, generally when the screens are full of debris it's a sign of internal engine wear/damage.

Your video was GREAT!! I liked the detail that you put into it. This was actually very helpful. Thank you
John Jackson Thanks, we appreciate the kind words!

great video mark love that MODIS
Fantastic video. Keep up the good work.
great video I was wondering how that vct system worked nice

Nice you were able to use a scope to spot a bad coil despite all the noise that was on that pattern.

so there are no other bolts besides that 1 bolt holding the camshaft in. I will now have to use force to take it out
+D'vawn Williams Yes there is only the one bolt holding the Camshaft variable valve timing solenoid in place.
