I greatly appreciate all the good advice.

I have bought the service manuals (not a Haynes Manual)

I plan to do a complete service (all fluids/filters) this weekend.
I will hopfully figure out what injectors the car has.

The car runs great so I may have gotten lucky that someone upgraded the fuel injectors/pumps system for me...fingers crossed.

I also cancelled the order for the weatherstripping, as too many times I ignored advice on forums and it ended up costing me. Will do some research on where to get OEM quality before I buy.

On a bad note, I have had no luck finding rear tires in Houston.
I am sure I will find sometime soon, but I want to drive the darn thing and I definitely dont trust the original tires.

The original relay is NLA although they can be found in a few places but the price is stupid high.
I did a write-up on my fix over at the ZR1 Net Registry, I'll have to go dig it up for you.

Minimum Restoration of a 1990 ZR-1

Needs a little Freon which you can get Freon 12 on Ebay.
Tires may have a flat spot which may go away with some driving.
I am surprised you do not have INFL REST light sitting so long outside.
Also surprised injectors are functioning sitting so long.
Overall....great find for such a low mileage LT5.

Change ALL Fluids as a first priority and do a compression check (should get around 210 lbs within 5 lbs on all eight cylinders).

Oh.....by the way.....I have 1990 #72 one of the first 1990s and the LAST 1990 #3032 sold to the public.
Thanks dynomite for sharing that!...BTW the infl rest light is indeed now on.

Nitto makes the correct sizes for a ZR-1. Check out this for their NT555
https://www.nittotire.com/Tire/Street/nt555#size
Discount Tire handles them.

My 94 has Nitto NT05's on it.

Changed all oil, oil filter, fuel filter and air cleaner. Was going to re-ground the Infl Rest sensors, below is the LH sensor (behind the battery). Looks like a black mysterious substance is seeping out.
