Easy flooding problem
 
Is there anyone got the same promblem?
My 88 GXL is very very easy flooding. Even I turn off my engine in hot temperature, it hard to start again. I need to unplug the eng int fuse(the second one in the fuse box) and start for 30 sec, then plug back the fuse. This is the only way to start my engine. Today, I tried 10 times doing the same procedure and the engine won't start. What should I do? If the exhaust has leaking problem will that affect? Is my engine blown? : (

You could set up a fuel pump kill switch to stop flooding

How to do? Make a switch before/after the fuse, so that I don't need to get out of the car?

Do a search-A lot of information.
Below from Ra Ra Rotary:
All i know is use the wire from under the steering column, i think its the big yellow one. Do not use the wire directly from the fuel pump.You need to find out why your car is hard to start.

Following fron Jason-NZ Convertible:
A fuel pump switch is not a fix, it's a band-aid. If it's hard to start because it's flooding, remove the injectors and have them cleaned (which should have been done during the rebuild). Dirty injectors are the most likely cause, and will be having other adverse effects other than hard starting.

In the mean time, a switch can be used as a temporary measure to get you going. Find the relay mentioned above (the plug's yellow, not the relay) and cut the middle wire. Solder some 2-core wire to the cut ends and run it to somewhere handy like the panel uder the steering column with the little vent. Install the switch there.

Thanks a lot, I will try!!

One more question, how do I know if the both rotors are still working? Is there any simple test? My car is hard to start, but after I started, it runs normally. Will a blown rotor just hard to start or will never start? Thanks!

Do a compression test. If one of the seals were gone, yes you would notice that. Engine probably just a little tired.

What psi is the minium for a rotary engine? Thanks for your help again : )

Rotorific 11-18-02 01:48 PM

90 on all three sides the bare nude minimum
