Well, I read what these codes mean. but the car wont start. I was driving and it stopped running like I disconnected a wire. and when I try to start it, it cranks unevenly, and it kinda acts like it wants to start. there anything else that I could look for???

So if you disconnect the map sensor or the tps will it start?

Ok I disconnected the TPS and it tried to run and wdnt then, then I did the same for the MAP no change. hooked it all back up and it will barely run if I floor the gas pedal. wonder if the PC went out? had this happen once before. but then it wasnt OBD II either.

you need to test to know more! What's the fuel pressure? whats cranking compression look like? Is the exhaust restrictted?

Not the exhaust. I will check fuel presure. I cant believe it would lose compression like this. I was driving and it just quit running. If I didnt know better I would swear that the timing chain jumped time. but this is just a guess. I would put a timing chain in it IF it was the problem but I dont want to tear it down then find out it isnt the problem

So it has low compression? It can jump time, not common but any engine can
Does it have good spark? If you spay injector cleaner into it will it try to start and run?
