no gas to engine.
im working on my brother-in-law's 87 he just got(he's in ID and its here in MT) it will sputter to life on a SMALL wiff of ether. i cleaned the plugs and the front rotor seemed to be a bit oil fouled ( its been sitting for a year or 2 because clutch went out )
i was cranking on it earlier today and found a gas line that was leaking so i put a new hose clamp on it and it stopped for the most part. i still have to get a better chunk of line to completely fix it. but the engine is dry of gas. im completely stumped on where the fuel pump is. it doesn't sound to be running when the key is on so idk. but there was gas dripping out as if it was a pressure line so i have no idea whats going on.

The fuel pump is in the gas tank. You can access it through a panel in the floor. Also, the pump will not run if the engine is not running, unless you jump the yellow test connector on the passenger-side shock tower, or prop the AFM door open.

what is an AFM door?
keep in mind this is my first time working on a rotary and we have to change the clutch when he comes up in 2 weeks aswell.

AFM = Air Flow Meter. It is mounted on the air filter box, and measures the amount of air going into the engine. It has a metal door that moves with airflow, which changes resistance values the ECU sees. It also has a fuel cut switch that is turned off when the door moves ~1/8 inch.

well theres 2 lines that feed in on the drivers side, and right now i cant get underneath. but the forward most line is the one that i can see that has gas to it because it is cracked and is bleeding gas, i have to fix that sooner or later.
