Starting/idleing problems
Ok last weekend my car started running worse and worse. It started out just flooding and I could start it by pulling the injector fuse. THe car would still idle though once started. Now I have to run a switch to the fuel pump and use the switch to turn the pump on once de flooding has taken place. Now it wont idle either.. Any ideas this problem has slowly gotten worse over 1 weekend. Any ideas, anyone experience anytyhing like this before..?

Check your overflow container for bubbles and a cloudy appearance. If that turns out good, it could be that you have an injector that's getting worse and worse. Run some injector cleaner through and see if it helps things any, if it's still a no-go, I'd scan for vacuum leaks, and pressure test the coolant system.

Well I have brand new injectors all around, I was wondering if a sensor or the FPR could cause these problems. I would suspect a bad motor but it runs good once started no smoke no funny noises or anything. The reason I would suspect the motor is because I ran the hell out of it last weekend with a BNR stage 3. Anyway everytime I thought it was the motor and others have said a motor I had done more trouble shooting and end up finding somthing like a broken injector clip. I never had a rotary go on me before so what exactly would I look for? Would it make any funny noise or smoke or somthing? Lately its just been flooding on start up but I do have 720 primaries. However I have had the 720s for awhile now and it just started this last weekend, then it got to where now it does not wanna idle either. So I dont know. I hate to pull a good motor and put in another one just to have the same problem due to a ECU or a sensor. Thats a lot of work and $$ just to discover it never was the motor. I had a problem about 2 weeks ago and discovered the broken injector clip, anyhow before I found the broken clip I did a compression test with a standard tester and had between 90-100 on all sides. So anyway just thought I would see if anyone had symptoms similar to mine and had it be somthing rather simple to fix
Thanks
Thanks

Did you do everything SonicRat said?
If you're adept at it, troubleshoot your sensor inputs from the ECU, using the FSM for pin # and voltage references...

Yes I did what Sonic suggested. Except the fuel injector cleaner, because I have a new Pump, Filters and injectors. I dont see how it could be dirt in the system. I will probably try it after all else fails. I guess I was wondering if a sensor could be causing this? Anyway thanks for all the input I will keep searching and troubleshooting. I will post when I find somthing out.
