hdi cut out

[ghandi0007]

There are two power feeds on the plug to the pump, one for the level sender and one for the pump itself. The pump feed itself will only receive power for the first few seconds after turning the ignition on, so you will only get a reading in that time window, hence why you need an assistant to turn the ignition on while you are testing it.

its going up to 11.7 v then droping to 3 afterwards just like you said mate , just took the lift pump out is there any way to check it , also whats the best way to clean it

thanks in advance
