After you pull this engine, I hope you figure out was wrong.

Once we got the fuel pump and new injectors installed, the car ran great.  I just don't understand why all these problems have popped up.    Didn't you use it for a daily driver for quite a while without issues?

2.    The few who learn by observation.
3.    The rest of them have to pee on the electric fence and find out for themselves.    Will Rogers

I know you have a new fuel filter on the car but when you remove the old injectors, look in the top to see if there's any crud there.  One of those sites we looked at suggested to always replace the fuel filter any time new injectors were installed.  If there's crud there, I'd change the filter again. 

When we replaced the injectors in the Fastback Formula, the tops of several injectors were totally plugged even though the car got a new filter.

It almost seems as if the injectors are plugged again.  Or, could be a bad FPR.

Yes, I daily drove it without issue for almost 9 months. Not sure what is the issue as I have searched out and confirmed function or fixed everything I could find save the injectors. With a motor almost ready to go in I am at the point of washing my hands with the current set up. Will spend the time working on the LQ1, the other work she needs, and Marilyn's new Vette.

I went ahead and removed the wing today and glassed in the holes. It was on my list but since it had begun to leak into the trunk again even with the new gaskets. So tomorrow after work I will start sanding and finishing the deck lid.

Got the T-tops in the Vette cleaned up, painted the lips, and installed new seals.

Hope to be in the warehouse on the 2nd or 3rd of April so the real work can begin. Hopefully the new motor and trans will be in and tuned by the end of the month. The Vette should be daily drivable by then as well. Also going to work on getting the parts Vette up and running as well.

Going to be a busy month of shelter in place.

It irks the heck out of me, when an issue goes unresolved.

It won't be unresolved, a new motor is going in 😜 was always the plan anyway. Will try to figure out what happened to her after she is out.

Been doing mostly body work at the moment. I am teaching Marilyn to wrench while we work on the 77 Corvette so I have been doing small things on the Fiero body work so I can be right there to help as she needs it. Hope to handle the port and polish on the heads this week but who knows if the weather will cooperate as my workspace is outdoors.

Lots of irons in the fire right now and my team just rotated back on for the time being so I am working 4 on 3 off 3 on 4 off till they say otherwise.

Just don't want you to think no one is interested in this.

I'm watching, too.  I don't always sign in, but when there's a new post, I check it.

Currently having a bit of a set back. The LQ1 that appeared properly stored before I got it wasn't. They actually sealed it up with water in one of the cylinders. Lots of rust and some bore pitting. Spent several slow hours honing with a three stone flex hone in hopes of getting through the pitting without opening it up too much for the stock piston and rings. Going to check the other block with the inspection camera soon and see if it is any better.

Not happy if I have to go have the brand new motor bored over and new pistons before it even runs.

Cause of the water I will end up pulling down all the bearings and putting new assembly lube in each and prepping it for start up over again for the factory.

I am glad I pulled the heads for porting though as it means I cought this before I nuked something on start up due to no assembly lube and a rusty bore.

"While you're in there...."  ;D

Replace the intermediate cam / jackshaft cam bearings with SBC cam bearings...  the OEM LQ1 CAM bearings have a tendency to disintegrate ..

Also saw they have these as you were asking about them as well (didn't know they had them offered)
