I have a 1996 Pontiac Grand Am GT 3100 V6 thats been sitting for almost 2 years without being started, I changed the battery and spark plugs and tried to start it, it turns over but will not start. It sounds like it wants to start but will not start.

Check for spark. If no sparks, suspect crankshaft sensor. If sparks are good, check for vacuum leaks.
Do It Yourself Diagnosis and Repair

There is a tool you can get on the internet or from
a tool supplier, to replace the front engine strut/
support, whatever it's called,you can look that up,&
it pulls the engine to the front,so you can sort of
get to the back plugs

Here you go good luck to you.

may be a coil pack. or even a bad spark plug. whens the last time the plugs have been changed?

Hope helps (remember rated this).

A code “multiple misfire” may mean that one or more of the following has happened:

•Faulty spark plugs or wires
•Faulty coil (pack)
•Faulty oxygen sensor(s)
•Faulty fuel injector(s)
•Burned exhaust valve
•Faulty catalytic converter(s)
•Stuck/blocked EGR valve / passages
•Faulty camshaft position sensor
•Defective computer

If there are symptoms such as the engine is stumbling or hesitating, check all wiring and connectors that lead to the cylinders (i.e. spark plugs). Depending on how long the ignition components have been in the car, it may be a good idea to replace them as part of your regular maintenance schedule. I would suggest spark plugs, spark plug wires, distributor cap, and rotor (if applicable). Otherwise, check the coils (a.k.a. coil packs). In some cases, the catalytic converter has gone bad. If you smell rotten eggs in the exhaust, your cat converter needs to be replaced. I've also heard in other cases the problems were faulty fuel injectors.

Random misfires that jump around from one cylinder to another (read: P030x codes) also will set a P0300 code. The underlying cause is often a lean fuel condition, which may be due to a vacuum leak in the intake manifold or unmetered air getting past the airflow sensor, or an EGR valve that is stuck open.

The firing order is ... 1-6-5-4-3-2

How much fuel pressure?

Likely cams are beginning to seize in the head. Usually this is the result of carbon plugging the oil pump pickup screen or internal oil passages. Changing the pump will not fix this unless your pump is inside the oil pan with pickup attached. If bearing surfaces on cam are damaged, you may be able to restore oil pressure but likely have already done internal engine damage which may extend to crank bearings as well. Generally at this point I recommend a replacement engine or vehicle. I really don't like telling people this.
good luck
