Q: have checked fuel relay switch ,have checked fuel injectors ,they are getting fuel.fuel pump seams to be working. out of ideas can anyone help?
A: If it runs on either but not on its own it has to be a fuel problem. Could be a loose wire, bad computer, bad fuel pump, plugged filter, or bad injectors. I would guess a bad fuel pump. I had a car once that quit and I knew the fuel pump was working but it was only putting out about half as much pressure as it should have. I replaced the pump and it ran fine again. I would put a fuel pressure gauge on it and see what it is putting out.
