88 rx7 wont start

I left it sitting for two days and when i went to go turn it on today it turned on then it slowly died and i could not get it to start up again even after doing the procedure for when the engine floods. The engine cranks slowly then it cranks fast. idk wwhat it could be. A fuel pump?

Sounds like the battery was low and/or the cables loose, then when cranking slowly it flooded.

Put about an ounce of oil into each chamber, crank over by hand, then repeat.

With a FULLY charged battery, try to start it.

Uh yes... a car will run off an alternator though. If it's good. Shim the terminals with some tin foil and try again.

no offense meant, but is there gas in the tank?

yes. check if the pump is making pressure per the FSM and if so, how much it's making.

It sounds as though it's either flooded or out of fuel.

Flooding can destroy a set of spark plugs, so even if you get it going, it may not run for long. You may need to perform the unflooding on your existing plugs, then once you are sure it is clear, swap in a set of new plugs.

Sometimes the only reliable way to start a flooded car is with a careful push start with another vehicle. That spins the engine fast enough to overcome all the excess fuel and oil in the chambers and will force it past that low RPM stumbling point.

Of course if there isn't any fuel in the tank, then that would be an issue.

There is a yellow test connector under the airbox. Jumping it will allow you to run the fuel pump by just tuning the key to IGN. You can jump this, power up the car and verify pump is running.

Pressure test procedures are in the FSM. But of course you will need a gauge.

Make sure the AFM plug isn't disconnected or loose.
