whays causing my van to not get fuel or not getting right amount of fuel?

No bc that's all I put in once it clicks that's it

ok,so( NO) to the check engine light on?

Check engine light has been on since I bought it 3 years ago. Never had any issues from the vehicle either.. my local machanic order the new part that was throwing on the check engine light but I won't work to fix it bc he says there something electrical within the wire I suppose he connects to it.. but he can't do anything bc the van never messes up on him.. but it Literally died on me on a busy road today with my Kids witch me

to many possibilities! if your mechanic can't find anything,then i would change the fuel filter first.make sure the arrow is pointing towards the engine when changing... then have the fuel pressure tested.
