I read through a couple of threads on flooding problems; specifically looking for details on installing a fuel cutoff switch on my son's 84 GSL-SE as a cure. I noticed, however, that several of you seem to believe that the majority of flooding problems are really due to injector maintenance issues.

Here in Atlanta we've been having cold weather recently and hence frequent flooding problems. I initially attributed the problems to the normally very short drive times that my son takes to get to school and back and thus the classic issues with not sufficiently warming up the car. This led me to believe I was experiencing the well documented ECU problem associated with GSL-SEs. But comments in several threads would suggest that I ought be looking at the injectors since the car has almost 100K miles.

It is also implied that continued flooding will cause other engine damage. Could someone explain a little more about this potential damage.

As all 1st GEN RX-7 owners I'm a shade tree mechanic and looking to save $$ by doing any required work myself. Was wondering just how difficult is the potential removal and replacement of the fuel injectors would be?

Thanks

 

First off the switch for the pump is a bandaid for your problem. On startup you should put the pedal to the floor Once to engage the fast idle cam. I would check your air filter if it's plugged also.

Can you elaborate more on the symptoms and during the situation that this flooding happens?

 

Start with 2 things, a can of Seafoam in the tank and have your son make sure the car is fully warmed up before shutting off. If that doesn't help, it's time to have the injectors sent out for service.

Most of my trips in my 2nd gen are short ones and often the car is never fully warmed up, I shut it off anyway. I don't have flooding problems, sent my injectors out several years ago for service.

Also check your plugs, cap and rotor. If they are worn or the plugs carboned, that will make starting harder and flooding easier. Make sure your son is filling up with quality 87 octane fuel and a can of Heet added to the tank may help too.

If you feel you need to add in a fuel cut switch for now, splice it into the ground wire, (black) under the driver's side bin that goes through the grommet in floor pan. Remove the rocker panel scuff plate and console so you can lift the carpet. Feed the wires underneath the carpet, a drill hole and mount the switch in the console. I prefer a rocker switch for this instead of a toggle. Mount the switch in such a manner that items in the console can't shift and toggle the switch.
