m50tub25 injectors not pulsing

[zachpepper]

i need all the help i can get. im out of ideas. i have a 95 obd1 m50tub25 with a red label 413 ecu in my 91 325i. my grounds are good and my power wires are good. when the injectors are plugged in both the red/white stripe wires, and the brown wires have power. i have the fuel pump wired to a switch so its getting fuel in the rail just not pulsing. iv tested both of my ecus and they both work.


someone please help!!!!!!!!!!!!

Replaced you're crank position sensor? Mine ohm'ed out just fine but wouldn't start. A brand new one cured it and fired right up.

yea i have 3 of them but there all used. there probably all bad.

Try a brand new one. Even if its not your issue, it can't hurt to replace it and eliminate the variable.

Before you buy a new one, is your ecu case bolted down?
