When my car was running, it was shaking & making a thumping noise & then I started to notice my car taking a while to get started & had to keep the key turned for longer then normal.I ended up leaving it sit for 6months & I started it up but it took a even longer then before & I left it sit for like 5 more months.I drove another car - got gas & put in. Then I tryed to start it but it wouldn't start & it didn't turn over or make the sound like it was going to start.I haven't tried to start it since.I was told it was the started but I don't know & can't find the starter to check. So if u could i'd like to know why it was shaking & thumping before it didn't start, if u think it is the starter & where I can find the starter under the hood please? I know it's a long Q with more than 1 but if could answer all or even most this for me I would greatly appriciate it. Thanks U guys

The starter is located under the intake manifold. You can not see it when you look under the hood.

OK, the starters' job is to spin the engine when you turn the key, that's it. If your battery is good and the engine spins over normally (about 200-300 rpms)when you turn the key, then the starter is doing it's job.

If your complaint is that it has to spin (normally) for a longer period of time before it starts, then the problem could be elsewhere.

If so, check the fuel pressure. There is a fuel pressure connection point (looks like a valve stem for a tire--has a black cap on it) at the end of the fuel rail on top of the intake manifold. Connect the pressure guage there and turn the key to the run position for not less than 3 seconds (you don't have to spin the engine over). Repeat this step about three times. The fuel pump should run for 2 secs each time, pressurizing the fuel rail and give a pressure reading on the pressure guage (about 45 psi). If the reading is significantly lower (30 or less) this could cause your situation. Also a partially clogged fuel filter could cause longer start times, as well. Let me know if the starter performs properly or if we have to check out the fuel or other system.
