2003 Safari cranks but doesn't start
My Safari will crank, but not start. It happened a few days ago, and I replaced the relay, then it started right up. The other day, it didn't start in the morning, but started up no problem in the evening. This morning it cranks fine, but won't start.
I hear the fuel pump, and changed the relay, still does not start.
Not sure if it is related, but the car has had some random misfires for a little while. We just haven't driven it very far, and that hasn't been a problem. The engine would run fine, but if we drove it too far or too long, it would misfire. After a day or two, it would run fine again.
Any suggestions would be appreciated.

a lot of the times the impeller will spin on the electric motor shaft which will still spin enough to move fuel but not enough to build pressure. I would say its time for a fuel pump.
