I bought the plug and play, sized my injectors (VEMS formula equated to 3.1), and she cranks really strong and healthy. Will not turn over. I am not getting any tach signal from my primary trigger (crankshaft position sensor), which I think is causing my startup issue. I tested the CkPS and it was dead accurate at 540 ohms.
If I set the secondary trigger to primary I get a tach reading, while cranking, of 140-180 rpm (I assume this means my camshaft position sensor is functioning properly). I have done some research and have read that running a secondary trigger is more advanced and is not necessary for initial startup (or at all in some cases).
If anyone has experience with VEMS and m50's specifically, please respond here or send me a PM. I don't want to waste time writing all of my findings here if no one can help.
Engine is 8.5:1 compression
80 lb Deka injectors
Thanks in advance,
