MFI Asssembly conversion

[dtl379]

Hi, does anyone know how to get my hands on any of the parts needed for the MFI swap out? I have searched everywhere and any time I try to ask GM, absolutely nobody knows what I am talking about. I swear-getting anything from GM about any problems I have had has been like asking the government about UFOs. I am the first to tell them of any problems

I have seen online that they are made by AC Delco, or that they are GM (I know both are connected). I have all the part numbers, unless they have been changed.

You can order it from www.GMPartsDirect.com Just type in the part numbers and it will pop up. The injector assembly is $147.98 and the mounting bracket is $17.16. You will also need a new seal kit $18.77.

You should also be able to get your local dealer to order it if you give them the parts numbers. This will probably cost more money though.

Didn't I send you the TSB? If not, let me know and I will send you a TSB that shows how to install it.

Hey blazee. Yeah you did send me the TSB, but when I tried many different sites, they all said the part numbers were inccorrect. I was just comming on to say I found them online at GM Parts Direct. It is considerably cheaper to get them online too. I called a local dealer (one finally knew what I was talking about) and they are really pricey:

The injector assembly was $269
The seal kit was $33
The bracket was $30

Giving us a grand total of $359!! After shipping and handling charges, GM parts direct has a grand total of $230! I think I will take that $129 savings and apply it to fuel expenses, or a new exaust. I think our exaust is messed up because of all this crap.

I was wondering, how fast will the clutch burn out due to the engine reving up to about 2500-3000+? Will a bad injecion unit cause that? We finally took the truck to have a drivability test done, and the tech said he could not tell anymore than the following:

1-distibutor off 1 tooth-he repositioned
2-leaks at intake manifold-we re-torched to spec (plenumn less than 2 months old, came with new gaskets)
3-o2 sensor bad-we changed 2 of them
4-ignition coil connection loose-we replaced
5-misfire on cylinders 2 & 3-we changed plugs, made sure proper gap

None of this has helped, which he said it probably wouldn't because the problems ran so deep. I am considering an autotap scan tool now because the engine will run for up to 5 seconds or more after turning off the ignition. With an autotap I can observe different funtions while the vehicle is running and hopefully pinpoint it. This is a pain the (enter word here) to solve when there is no SES light on.
