787 rfi one injector flooing, help please
I have a 2001 gtx 787 rfi and the front, mag injector sprays a lot more gas than normal. I pulled the rail out and cranked the motor, the rear injector sprays normal but the front one sprays a lot more than normal. I put a container to spray in it and in few seconds it sprayed one ounce. I switched the injector plugs front with back one and the back one was spraying more. Anyone knows what this is, ecu maybe. Please help.

So, nobody ever seen this? I am looking to change the ecu, I hope that's the problem.

sounds like an mpem/ecu problem..no maint light on the console?
I have a spare mpem..but I suspect it has a fault in it on the map sensor logic..I also have a fuel injector rail
I assume you're hydro locking a cylinder based on that fuel flow?
what's the symptom?

I got it, the moisture inside the ecu housing was the culprit. Now it starts and runs fine.
