Sr20De, will not stay running.

Ok, So now whats wrong here. I installed radiator hoses and a new radiator into my 240sx with sr20de engine. I start the car it runs fine and everything I get all the stuff in clean up and take it for ride.

I get back turn it off and start trying to figure out why it idles is so high. (Another problem all together) anyway So I go to start it again and then it starts ups and starts jerking and jarking and shaking then just dies. I try again and this time it stays running for a little longer but just Shakes and Chugs badly then I touch the gas and it just dies right then and there. I play with it for a while and then unhook the Neg. Battery cable let it set for about 5 mins.

Guess what Now it runs and idles I say Ok cool. So i take it for a cruise and come back turn it off turn it on about 10 times No problems what so ever. Then I go to get in it about 30 mins later and it does the exact same thing again just chugs and slugs till it dies. I pull the cable again and it worked again. !!!!!

DOES ANYONE know what the hell would cause that... I have never saw it before. I know it has to be ECU or at lest I thought since I am pretty much clearing the codes in the ECU. So i checked the ECU and the ECU says 55 which means nothing wrong your screwed.

So anyone have some input. The only thing I did was I was trying to figure out what was causing the high Idle I had placed a Cap over the big line coming out of the top of the Thortal body but why would that cause this problem. I even put everything back to the way it was and its still doing this.

Thanks

Well, bed time I guess everyone is as lost as i am.

When you say you pulled the cable and it worked fine, which cable are you refering to? If it's your battery cable then I would say you have a loose, broken, coroded battery cable ends.

Could not having a proper ground cause this problem? Because I remember I had my girlfriend start the car and it was doing the chugging and trying to die. I then had her turn it off and I wiggled the NEG. battery cable and she turned it on and it ran fine.

HUmmmmm

I pulled the Neg. battery cable off the battery waited around 5 mins put it back on then the car will run fine.

Yesterday It was running great then I took it for a ride for about 2 mins and came back parked and when I went to start it again it was doing the rough rumbling chugging dieing thing and then when i touched the gas peddle to give it gas it just Died. I pulled the battery cable for about 5mins and it worked again.

I didnt know if 240sx do this when there isnt a proper ground or something.

But the part i cant figure out is after it Dies from chugging and rumbling, I can turn the key and the motor will turn it just wont start until i pull the neg battery cable and wait.

??? I tried reading the ECu but it says 55 So I am really confused about this.
