Having problems with your 2004 Nissan Sentra ?
2004 1.8l nissan sentra what now? not battery or fuel pump/filter
\015 I was driving on the highway and my car started to putter and would not go over 20 mph. i took it to the shop and they told me the fuel pump. we changed it in october. I still had problems for about 3 weeks and took it back to the shop and they changed the fuel pump again saying that mabye it was a bad one. Still having a problem a week later I took it to another shop and they checked a lot of things and put in a new battery, checked and fixed some wiring, reset the computer, and changed the fuel pump again. Still having a problem. When I try to start the car it will not start unless I give it gas and I should not have to because it is fuel injected. Sometimes it takes like 20 minutes of continuous cranking and pumping gas to get my car to start I have it back in the shop again and still no answers, can anyone help me please?!?!?!?!?!?\015
Check your catalytic converter. If you are over 80k miles, these devices will wear in stages. The first stage of wear is slower gear change at cruising speeds when approaching any type of incline. Second stage is the engine light will reveal a faulty oxygen sensor. Because the converter is basically a "filter" built into the exhaust system, it wears by slowly clogging, which leads to no starts, no power, and sometimes a blown head gasket. If your mechanic removed the oxygen sensor before the converter, theres a strong chance it would start right up.
There's a recall on all catalytic converts w/ 2004 Nissan Sentras. if this is your problem go to the dealer. I had mine replaced for free January 2009.
