ILIA Posted November 12, 2010 Share Posted November 12, 2010 Sounds like a bad mass air meter. It's the electrical sensor on the intake where your filter is. Quote Link to comment Share on other sites More sharing options...
ILIA Posted November 12, 2010 Share Posted November 12, 2010 Sounds like a bad mass air meter. It's the electrical sensor on the intake where your filter is. Your computer won't give the code unless the problem is happening and that usually takes a few miles of driving when they just start to go out. 25 bucks max at a salvage yard. Good luck Quote Link to comment Share on other sites More sharing options...
Maineah Posted November 13, 2010 Share Posted November 13, 2010 You might want to stick a fuel filter in it bet its never been changed when you see where it is you'll understand why! Quote Link to comment Share on other sites More sharing options...
Sunnynshare Posted November 15, 2010 Share Posted November 15, 2010 The fuel filter is attached to a bracket that is attached to the block under the EFI. You can best see it from underneath. Before changing the air flow thing I would troubleshoot it like suggested here. Kim Quote Link to comment Share on other sites More sharing options...
ILIA Posted November 17, 2010 Share Posted November 17, 2010 Switching the electrical component takes about ten minutes and any unskilled mechanic can complete the job easily. Plus it's dirt cheap and there's no need to buy new. I am convinced that the mass air meter is your problem. And it wouldn't hurt to put in new plugs and an 02 sensor since it was most likely causing you to run rich. Those parts are cheap as well and simple to install with the right tools. Good luck Quote Link to comment Share on other sites More sharing options...

WME Posted November 18, 2010 Share Posted November 18, 2010 Throwing parts at a problem is expensive. Beg or borrow a fuel pressure gauge and check your fuel pressure. If its low nothing works right. Low pressure can be a bad fuel pump or a clogged filter. A filter is cheap but a PIA to change, the fuel pump is expensive and a real PIA to change. Have you tried to down load the stored trouble codes in the computer?? Quote Link to comment Share on other sites More sharing options...
Maineah Posted November 19, 2010 Share Posted November 19, 2010 Listen to WME the parts can get expensive fast. I doubt that it set a code unless it was some thing emission related. Replace the simple/cheap stuff first the fuel filter is some thing that should be replaced regardless if it's your problem or not. From your explanation it sounds electrical more then any thing else probably killing the pump. Now here is the deal the air flow meter does play a roll ILIA is right about that, inside of the meter is a set of contacts (pins 1 and 2) that holds on the the fuel pump relay when there is air flow. When you first turn the key on the pump runs for a few seconds then stops. There is enough fuel pressure to start the engine air rushes through the air flow meter and closes the switch the pump runs again and will do so as long as there is air flow this is where the fuel pressure gauge comes in. The pump must deliver around 35 psi to run properly now the air flow meter is not the only thing that can cause you grief so unless you are methodical you may end up replacing a lot of parts you don't need. It's going to be hard because it runs fine now I would suggest wiggling the wires to every things that has any thing to do with the pump while it's running and see if you can make it stop. A manual is cheaper then just one part. Quote Link to comment Share on other sites More sharing options...
