I see it Benny, FICM at the top of the first and last pic, heat shield for the y-pipe in back (with bolt missing). Single wire going to #8. That's the next to last on drivers side.
Yes the pics are of the #6 injector..... What do you guys think? Do you agree that it has NOT been replaced? I know where #2 is, I just cant get a good look at it without removing at least the intake tube.
It looks Like there was a Finger Smudge in the one Pic
I mean if they changed it the FICM Had to get unbolted and moved maybe they left plug in IDK
They do it llittle dif than us they move little as possible they never clean nothing nless theres a Seal in question
But the Valve cover Had to come off and the FICM had to move for that so
as dirty as that moter is would think there some definate marks wherethey grabbed stuff to move it
The Way I see it is your first code you had Could have been a Loose FICM Harness or bad FICM or Bad Inject so if that other stuff dont look disturbed then
So I just got back from the dealer who did the work. The service manager gave me the whole "well you cant see it blah blah" so i asked to talk to the service tech there....he said " I did not change #6, but I did change #2." That makes me feel a little better, but I will be removing the intake tube after work and doing some more inspecting.......I didnt want to remove anything before going back.
UPDATE!!! So it does look like the #2injector has been changed.......... After work I went to home depot .... Got what I needed and went to start the truck..... It started and stopped about 2 seconds later..... Now it does not start at al just cranks and cranks got it towed to the same dealer... Only put 30 miles on the truck and now this!!!! I'm thinking that a high pressure o-ring blew.... Something that was removed then reinstalled without replacement during the injector job.....
What would you guys do now? I absolutely needed the truck this weekend also
Any new codes?
What are the ICP and IPR duty cycle readings when cranking?
FICM voltage? FICM sync? Cam/Crank Sync?
I guess I would be gearing up to do an air pressure test on the HPO system (depending on the answers to the previous question).
The dealer said that they would try to get to it today
They also said that if it has to do with anything they touched it will be covered free of charge... I'm hoping that it is something stupid because i was less than thrilled at the way the work was peformed at the time of injector replacement. They didnt even wipe off the valve cover of crud!! I will keep you guys posted.....never again will i go to a dealer, work will be done by myself from now on...
On a side note....do you guys generally recommend the scangauge2 for diagnosing issues? What am i limited to with this? Thanks!
First, what it won't do:
Fuel pressure
Exhaust gas Temp
Low (crankcase) oil pressure*
These values are not monitored by the engine computer, there are no sensors under the hood so the SG can't see them.
What it will monitor:
Fuel Level
Battery voltage
Engine coolant temp
Engine oil temp
Trans fluid temp
Intake air temp (on 2 different sensors)
Injection control pressure
Injection pressure regulator
FICM (fuel Injection Control Module) main power
FICM vehicle power
FICM logic power
FICM sync status
Camshaft sync status
Crankshaft sync status
Fuel injector timing
Fuel injector pulse width
Fuel injectors 1-8 on/off commands
Radiator fan speed
Radiator fan duty cycle
Barometric pressure (ambient)
Exhaust back pressure
Turbo Boost (by tinkering with baro settings)
Turbo duty cycle
manifold absolute pressure
Accelerator pedal position
V-ref voltage
Trans shifter position (automatic)
Mass Fuel Desired
These are the main ones. People are still tinkering with codes for misfire counts on specific cylinders and there may be a couple more I missed. In addition to these gauges, the SG has a trip computer that calculates fuel mileage and trip time etc. It also scans for many (but not all) codes that may have been stored if there is a problem that turns on your Check Engine Light. It simply plugs into the OBD port under the dash so install is easy also, and finially, the price is right.
Now for the negative:
The price is inexpensive because it's inexpensively made. The display is LCD but the dots are pretty coarse and it can be hard to read (the color of the backlight can be changed which helps). Half of the gauges you will want to monitor require you to input long strings of numbers to "program" into the unit, it also must be plugged in to do that so you'll be sitting in the driveway for awhile when you first get it. and finially, it is what it is, there are no options to hook up additional sensors to allow it to display the values I mentioned in the beginning.
There are other monitors with touch screens that can be expanded to show the other gauges, like the Edge Insight or DashDaq. These monitors are considerably more expensive but the expandability is important and besides that they just look better. Back-up cameras, mp3 capability, and the ability to completely change the way the screen looks is pretty cool if your budget allows it.
