Hello I just picked up a 86 rx7 that's been sitting garaged for over 16 years I've put oil in the plug holes and manually turned over no problem when I turn it over it gets spark I just don't know if it getting fuel kinda can hear sound comming from the pressure regular when turn key on but don't smell any fuel anyone know if injector plugged?
Welcome to the forum! Would love to see more pictures of the car! It looks to be in decent shape! Do you know any of the car's history?
With sitting that long, expect to replace the fuel pump and filter, drop and clean the tank, and expect the fuel injectors to he gummed up with dried gas. We can get more thorough in the 2nd gen tech section as this is an intros section only.
As mazdaverx713b said, with it sitting for as long as it has, please do yourself a favor and drain the tank. It will give you a snapshot of how what the fuel tank looks like on the inside. There's a plug on the bottom edge of the tank, visible from underneath the rear bumper.
I'd also recommend pulling the fuel pump too. Getting to the pump is pretty easy. Lift the hatch carpet, look for an access panel with 4 Phillips head screws and wiring poking through the middle. The Pump is under it, secured to the tank with Eight M4x0.78 Phillips head screws. Pretty good chance they've been in there since 1986 and are heavily rusted, so soak them liberally with a penetrating oil (PB Blaster, etc). Do so again in 12 hours, then once more after 24 hours before even thinking about bringing a screwdriver to them.
One thing I'd STRONGLY SUGGEST is to get a 1/4" ratchet, spinner handle and 1/4" drive screwdriver bit set. Use one hand to exert as much downforce as you can onto the screws, and the other to turn the ratchet. It's gonna suck, but this is how I removed mine years ago. Replace them with stainless steel bolts/hex cap screws.
Once you get the pump out and the tank drained, I'd cycle some fresh fuel through the fuel lines and rails, then drain and repeat until it comes out clean. When doing so, just turn the key ON and plug a jumper wire into the Fuel Pump Test Connector (see wiring diagram on foxed.ca). Some fuel system cleaner/treatment from Autozone/Walmart/etc probably wouldn't hurt either.
On the plus side, you have the 4th set of original Finish Line (dealer accessory) Hatch Louvers that I've seen. They're quite rare as few of them survived.
