Yesterday on my way home my 89 p/u 22re started sputtering and buccing it cleared up and was fine rest of the drive. Today I start it to leave starts right up idles fine give it gas and cuts out but still is idling fine for few minutes then starts sputtering and choking out till it finally dies. Its getting zero fuel pressure the relay is good so I'm thinking the pump was on its way out and finally bit the dust but want to be certain before I change it any tips would be good as I'm new to toyotas and don't know the usual bugs or glitches they might have
