I have an '85 MR2 and last summer my fuel pump stopped working. I took it to a shop and they replaced it for $700 total including labor. I also replaced the fuel filter right before taking it in. I have only driven the car a couple thousand miles since then, and I think the fuel pump is bad again. It is showing the exact same symptoms that it did last time it failed. The engine started intermittently sputtering one day, and then died. So my question is, how could my fuel pump go bad after 1 year and only a couple thousand miles? It sat in my garage for 4 months (Jan-Apr) and never was started or driven. But I put fuel stabilizer in the tank so I don't think that was the reason.
If I buy a fuel line pressure gauge and determine that it is in fact the fuel pump, I would like to try to replace or fix it myself this time. Can anybody tell me how hard it would be to remove the fuel tank and troubleshoot this problem.
Thanks for any help. If it turns out to be too much trouble, this may mean the end of the MR2 for me...
