when i went to de flood the engine there was a big spray of fuel from the rear, the front was dry. car has been sitting for 2 years so im thinking the rear injectors are stuck open and the fronts are ok because ive got it running but it wont idle and sounds like its only running on one rotor.... anyone have an idea of how to test my theory? would rather test and get the bad ones rebuilt rather than spend 88 bucks and get them all rebuilt. car is a 86 with hi imp injectors.

 

Strap/secure the injectors to the fuel rails. Unbolt and remove the fuel rails. (There's an illustration of this in the 87' FSM. "Fuel and Emission Control Systems" 4B-74) - Obviously you do not remove the injectors or any of the fuel lines. Be sure to set some rags or something under the injector's fuel outlet nozzle, to absorb fuel in case they are stuck open. Jumper the yellow fuel pump test connector at the passenger side strut tower, near the AFM. Turn the key to "ON"... Not to "START". You'll hear the fuel pump running... Now go check the injectors to see if they are spewing/leaking.

It's a sure fire way to see if your injectors are stuck open.

If you do not have a Factory Service Manual, here's a link to some FSM links: https://www.rx7club.com/showthread.ph...18#post5131218
