Have you checked the pressure on the fuel rail to see if the pump is failing?Lately, My fuel pump has been giving me stuttering starts and an inaccurate fuel level on the cluster. I didn't realize the prices were so high. I'm curious if anyone who has replaced a fuel pump has used an aftermarket one. Was it ok to use it rather than OEM, or was it something that was regretted? What was one purchased if it all worked out? Thank you in advance for your responses.
When mine was giving me fluctuations at idle and rough starts, problem was intermittent crank position sensor.
As to fuel level indication, had that too. But after a few times of allowing the tank to get low, like 1/8th,, and filling, that stopped. Think I needed to let the float full travel to clean up the signal.
Not saying yours is doing the same, but some more troubleshooting before condemning the pump.
Because it is a p.i.t.a dropping the tank to replace it.
BTW, some model, engine info would be helpful.
