Anyone, i have a Ram 500 with a new Flightworks 200 pump and a new ECU from Bob (Ro3B),my problem is after ramping i start to throttle up and about 1/2 throttle the engine coughs and shuts down with a cloud of smoke. Does anybody have an idea what i can do???

Thanks Pat

Yes ...search RCU threads for the information you are looking for

Actually there was just a resent thread with almost the same title as yours and it is quite interesting....

Look around post #7

Was the engine runing ok before the upgrade?. Some time the new pumps will push more fuel than the old pump causing the engine to flame out.

(Simple test) try throttling the engine slowly to full power with in 10sec. If it runs then Its a electronic ajustment,, If it flame out then (COULD BE) Some block injector.

basimpsn, the engine runs fine after ramping i waited for a little longer than 10 seconds and advaned the throttle one click at a time it runs up fine to almost 1/2 throttle then coughs and shuts down.

thanks for the reply

I would guess its your injector then (IM GUESSING NOW) As RCISFUN says there is a lot of information here like this one showing a block injector before and after .

Thanks For the Help

Pat,

I agree with basimpsn that you have a blocked (dirty) injector. Mine acted the same way until they were cleaned.

Just my guess from my prior experience.

Well,,, normally you would have to go deeper. But if you are getting 156k thats good [sm=thumbs_up.gif]. Remember to check the tail cone screws every now & then.

Good Job

Like pull the fuel ring and clean it in an ultrasonic cleaner, then do the flame test

Yep,, thats what im talking about

YOU GUYS ROCK, all the info i have recieved has bin very helpful and it seems now that my Ram 500 is up to snuff. Thank you again for all your support.
