I had an evap prpblem died hot changed purge sencor & fule pump & it ran better, but now has got weres ,starts & idles fine but dosnt take fule on road if you ease in to it it will go 2 or 3 miles then dies restarts & idles but dies at take off will pull its self at idle but thats it.

clean the maf? check fuel pressure? access to live data?

I know you changed the fuel pump, but it sounds like a fuel pressure issue to me. Did you change the fuel filter? Pull the vacuum hose of the fuel pressure regulator and smell for gas in the hose? Get the fuel pressure tested.

I changed fule fillter & no gas smell in vac. line cked maf sensor with multimeter hot & ground are good have 2.5 volts on 3rd wire dosnt change when i excllerate. so maf is bad right?

you cant tell the maf output really without reading it with a scanner
