96 Sunfire GT. 2.4 5Speed
Crank, but won't start. Has been acting up, spitting & sputtering lately, high Idle, then
like it runs on 3 cyls. Had it to the dealer last week because the PCM had a 1 inch split
in the bottom, & was getting wet inside. So PCM was replaced & reprogrammed by
dealer. CEL came back on, has a P0108 MAP/BARO HIGH CIRCIUT EVENT. So, I
replaced the map sensor & disconnected the battery for ten minutes. Still runs like
crap. So I let it sit overnight, & now it cranks over, but won't start at all. Any ideas?

Its possible that your Crank sensor is bad. First before i'd replace that, i'd check for spark & fuel, if your plugs are getting wet & you have no spark, i'd test the coils & ign. module to make sure they are good. If those check out ok, then i'd move towards the crank sensor, if thats bad you wont get spark as it tells the ECU when to fire.

So the crank sensor could make it run like crap first, & then quit all together?

Yes the crank and cam sensor will both make the car run like poo before they go out completely .. they control the timing.
Get a cheap set of wites that will fit on the coil housing and down inside the spark plug holes. Then check it spark like any other car.

Hit 200 NA it broke once, Hit 213 it broke again,
Hitting 300 NA is further away than I thought.
Will it throw a Diagnostic Trouble code for that or not always??? This is wierd.

I think it's the fuel pump, because I can't hear it running when I turn the key anymore.

Ok, replaced the fuel pump & now it runs again,
but the car is still running a little choppy, & the CEL
light came back on & shows a Knock Sensor code now.
Also the as pedal gets hard to push at times. Any ideas?

I've got a bad knock sensor in my car. It doesn't happen all the time, but when it does, it runs really rough at an idle, and will throw the code for cam and crank knock sensors. Then it'll just disappear all of a sudden. Goto a junkyard and scarf one off of a car and try that.
Beat it like it owes you money
hmm
