so this is full throttle on a 2004 jaguar xk8 pump has been replaced. I would love an opinion as to what the wave form reads I'm new to pico so any help would be appricated
Hi.
First of all, you should check the FP MODULE.
Poor mass or power contact of the ECU.
There may be oxidized contacts.
In IDLE mode, the pump current is clearly understated.
Only in the area of the marker 7.625 sec, the current is approaching the nominal.
In WOT mode, the PWM signal increases, and the pump current should increase accordingly.
On the provided signal, the pump current becomes even smaller and chaotic from 30 sec.
