Looking at new injectors, input needed

[Tilt]

Tried to start the truck for the fist time this week. After a couple of self inflicted hurdles, I got it to turn over, but it would not start. Bled all the air out of the fuel line, Have 55-60 lbs fuel press during start up, checked all injector signals with a noid light (all good) and have spark on all cylinders. I pulled the injectors yesterday and soaked them in Seafoam for a while and sprayed out the fuel rail. After soaking the injectors, the truck will start with starter fluid and will run rough but will not idle. It will not start without the starter fluid. I also noticed that only 2 of the header tubes were getting hot (roughly 500*) all the others were 160*-260* shot with a temp gun. The harness is a new BP Automotive, andd he also did the reflash on the ecm, so I am assumiing that VATS has been removed. Engine is a 2004 LQ9 with 243 heads and a new cam speced by Martin at Tick Performance.

Now to my question. I'm looking at just getting new injectors instead of messing with these originals. In my search the AC Delco 17113698 comes up as factory replacements. I found these on Ebay and they say new condition, but the price is half of what i have found elsewhere. http://www.ebay.com/itm/ACDelco-1711...-/350617736602
Has anyone else tried these? I'm just a little leery about them being fakes or something. Are there any better factory replacement injectors that I need to look at? I'm hoping to get some ordered tonight or tomorrow.

Well, after typing all this out, Summit will price match them and I will have them tomorrow.

I have a full set of stock injectors for an LQ if you wanted them.

OTherwise honestly I'd spend a few extra $$'s and convert to the EV1 or EV6 plugs and their way more bountiful options.

This is a common problem with ls engines that sit around . The injectors will get gummed up and they will stick and do what you have described . New injector will fix the problem but 99% of the time it is not necessary . Just a proper cleaning . Soaking them does hardly nothing to clean them .There is a inexpensive way to clean them . I made a homemade injector cleaner with a syringe and carb cleaner a switch and a 12v power supply .It allows you to flush then in both directions also. It worked great . Look on YouTube and you will see lots of info . Pretty easy to make and a lot less expensive .

Thanks for the offer BR3W, but I already have the new ones in and got her fired up. I'll keep the originals and clean them up later for spares or for the next swap. Now to get the driveshaft, exhaust, and shifter cable hooked up and a little tidying up of some of the wiring and she'll be ready for a road trip.

Did the new injectors cure the problem?

How do you like the BP harness? I'm about to order one myself

I really like it. Great quality and was money well spent as I hate wiring.
