Can you check for any vacuum leaks?

Big.. this could be an ECU issue. Could be a fuel pressure issue, could be an ICM issue.
So far.. what do you know about the car.
Has it been acting this way for a while?
Was fuel that might have water in it, just put in?
Has the fuel pressure been checked?
On the plugs, bosch plugs break down quickly in a waste spark system, our cars do use this system.) However..you should be able to figure out the problem before changing them. They are too new to worry about at the moment.
Also.. please use the below Techinfo procedure to pull any diagnostic codes

ive only had the car a few days, the guy i got it from said he changed the coil pak is this the distributor? he checked the fuel pressure said it was good, only thing ive done is put in premium gas and octane booster, and a bottle of injector cleaner he said the gas had been in the car a good while but im still perplexed about the inst. panel thanks guys for your help.
one other thing ever since i got the car last week the check engine light would come on for 10-20 seconds and then go back out (if that helps any)
i know i sound stupid but what is an icm, and a ecu thanks

There are no stupid questions here.
ICM is an Ignition Control Module, you asked if the coils are the current replacement for a distributor. The answer is, basically yes. The ICM monitors some of the sensors and tells the coil when to fire. Together they replace a distributor.
On the gauges. I understand it is annoying. Let'* put that on the back burner at the moment and concentrate on getting the car running. Clusters can be anything from a water leak to a bad connection/cluster. The cluster will not keep the engine from running though.
If the fuel pressure is good, plugs and wires are new, then we are certainly looking into issues like the ECU and ICM.
Before we jump to diagnosing either of them, please pull the codes. Even if the light flashed briefly the computer should have stored the code.
Also.. please list fo me the numbers on the coils from top to bottom aka from rear of car to front. I am speculating that the coils were moved around and firing order may be off.

Transposed coils is what kept my car from intially starting after a full rebuild.
Now then, these coils...do they have numbers on them? Factory coils should have numbers on all of them, with the numbers corresponding to where the respective plug wire goes to. If these coils were replaced, or shuffled around, that would be a huge reason why you are not starting.
Keep in mind that overall, the numbers on those coils do not matter. What DOES matter is where the ignition wires go in relation to coil position.

Also...get us the position of the coil numbers. If possible..check that the wires are either in the position stated on the coils or not in those positions.
