floded rear rotor - new reman engine
#1
just got done installing a reman engine and on inital startup it ran very rough, like on one rotor only (12" vacum). replaced the igniter, coils, and ecu to no avail. I used a timing light on the front & rear T wires and picked up a signal on both of them. Havent actually pulled the plugs for a visual spark test yet. I did however pull all the plugs and noticed that the rear plugs are squeeky clean, but soaked in fuel, as was the rear rotor. The injectors were cleaned and balanced by RC.
I then un-flodded the engine, started it and same problem..rough, poppy, and fuel actually leaking out of the turbo contrl actuator pin . I hooked up a timing light while it was running (barely) and still picked up a signal from all plug wires. As of now I am kinda stumped so if you have any suggestions please post them.
I have an ectra set of injectors, as well as rails I might swap out in the mean time.

Old secondary injectors are not leaking, but I did notice some "smoke" coming from the rats nest while the the ign and Fpump was on, I couldnt pinpoint exactly where it was coming from but the Solenoid Switching Valve plug (C on the vacum diagram) was rather warm. It just has a 37 ohm resistor jumper (simplification).

I think I found the source, the secondary injectors> the rear is stuck open, and the front is leaking , which is sweet since I had them inspected, cleaned and balanced

It was more denial than anything in my case. I just kept telling myself it could'nt be the injectors, they were just cleaned & balanced.
I'm also wondering about the proper resistors for vac simplification. Still running sequential, just none of the extra crap. I measured the resistance of the solenoids @ 37ohms, but I also found some threads that suggest a 330ohm 1/4watt resistor. Does the resistance have to be measured under power or does it matter? Or does anyone actually know what the proper resistors are? Oh yea, still using the stock ecu.
