Back again: Starting issue
I have a 2002 nissan sentra gxe. it has 120,000 miles on it. We have only owned it for about 3 months and have replaced the plugs and wires, did a fuel injection on the vehicle, added fuel treatment to the gas, oil change, all that being said,
I had a problem about 3 weeks ago where the car was starting, having a high idle, it would shake, then when it was put into gear, it ran just fine. I got a couple codes for misfires, and noticed that my gas mileage was half what it normally is. The car got where it wouldn't start every few times I started it. Then it got where it needed gas to start. Then it quit starting altogether. It would crank, but would not turn over. Each time we tried to crank, we seemed to be able to hear the fuel pump. Tried replacing the coils, tried switching around fuel pump relay to see if that was the problem. Finally ended up replacing the cam shaft positioning sensor. The car started and ran for a few days. Then guess what???
The car is having trouble still. I do not know if any of the previous things mentioned have anything to do with this issue but felt the background may be helpful. The car got to where it would not start again. Sometimes it will start if you give it gas and usually a lot of gas, but obviously I do not like nor do I want to do this. Once it starts, you can try and restart it several times and it will start right up like nothing happened. But, it seems once you leave it setting for a little bit, it won't start. I did notice this morning that it is not just in hot weather as someone had asked me that, because it was in the 70s this morning and it still had the same problem. It seems that once you get it started it is fine and it even runs fine, no codes, nothing. But let it sit for a little bit and you'll have to work to get it started. Any suggestions????
