Theres no gas in it we are pretty sure its the injection pump

I got fuel like two hours before started doing it and for RPM I don't know Cause I don't have a tach But it sounds like it's a loping around 500 RPMs up-and-down

I think like 170k

no

it is a 90 with 726hd and only at idle and new fuel filter

I was driving it last night and it just started loping can anyone help
