Last Thursday while driving about 80 on the freeway my gages in the car started going crazy. They were acting like i was just starting the car. I had to have the car towed back to my house, since then it only stays running for maybe a minute if we can get it started. We have replaced the fuel filter, checked the fuel pressure, as it sounds and acts like its not getting fuel. We checked for codes with a scanner and didnt get any. We checked all wires everything looks good. We check for spark and we are getting erratic spark. I don't really have the money to start replacing things so we are trying to pinpoint what the problem is. We thought it could be the camshaft position sensor or crankshaft posistion sensor, or the ignition module. Before we start to replace those we want to know if there is a way to test them. Is there anything else that it could be that we havent tried. Please help me, I am stumped as is my friends who are trying to help me, one is a mechanic.

Check the fuse block under the hood and make sure it is secure. Do a search for 2000silverbullet, he had an issue with his block a few years back.
Bad grounds can haunt you as well. Here'* alink to a good tech info write up.

Please explain what you mean by 'erratic spark'.

I'm sorry if this isnt exactly right I have been there when they have been checking anything but I am a girl and don't always remember it correctly.
In the process of checking everything we were checking to see if the spark plugs are getting spark. Sometimes we get good spark others we get no spark. If you need more on that I will have to ask my friend to explain it a little better. I'm sorry.

No reason to be sorry. I'm just trying to get as much info as possible. If there'* times when it'* not sparking it'* usually the ICM or Crank sensor. I'd say we see 3 or 4 times more bad crank sensors than bad ICMs. Good news is the crank sensor is a lot cheaper than ICM. Bad news is it'* harder to change than the ICM.

the only thing they were concerned with is that there is no codes when they scanned for them is that ok that it not showing a code

Bad crank sensors don't seem to throw a code very often.

Thanks we will try that this weekend.

Sounds like a coil problem. I would replace the coil that cooresponds with the cylinders that you found had eratic spark. You did the test and got the clue... It could also be plug wires on those cylinders.
When I had crank sensor problems it always threw the crank sensor code... And these problems sound a little different to me than crank sensor.

It was all three coils so we didnt think that would be the problem.
