Huge jam! 03 grand prix GT
New to site/thread,
Absolutely in a jam with this car, recently moved across country to arizona from ct and I feel all my issues started, I've only owned since July 2013, it now has 155,000 miles, right after purchasing I put a brand new gm factory built transmission, shortly after coming here my car died, my only semi mechanical freind found it was the fuel pump, in a limited budget u got a cheap fuel pump, had to put a different wiring harness on then what came with due to manufactor issues. I feel like shortly after my check engine light came on, so had him check all lines again and looked good,have had codes EVER since, needless to say car ran fine with engine light on, until in the past 3 months I've put over 3k into the motor, having done upper aND lower manifold gaskets, plus hoses and thermostat and water pump, month after that felt a slip in tranny, checked fluid and was down 4 quarts, bring to a dealership because transmission is under warranty only to be told my transmission cooler erupted in the radiator, soo 1,800$ later I have new radiator,reservoir, thermostat AGAIN, upper and lower hoses AGAIN because we're swollen... dealership pulled codes but NON had to do with tranny so they ignored because thays not why car was there, codes they pulled were P0440,P0446,P0453,P01441, I've looked up codes I know most have to do with evap system but how can I fix this!? On a very now fixed budget because of these larger issues occurring before fixing the engine light problem. Also since lights come on I've replaced gas cap, spark plugs, purge valve, latest issue is just randomly dying at idle, been in middle of busy intersection and just shuts off, starts short time later, changed fuel filter couple days ago, things seemed fine and actually light dissapeared, then died today when I went into gas station, I've eead alot,watched videos for changing sencors ect... but I'm alone out here and in need of some trouble shooting and advice! Please and thanks

No, this week I became familiar with most the sencors, the first shop who did manifold gaskets said it'* the fuel pressure sencor, but would that one sencor really cause all those codes? Also how many o2 sencors are there? I almost feel like buying all new sencors for everything just wanted to save money and pinpoint it... do I clean the throttle body? Do I u plug the sencors and clean with electoral parts cleaner and plug back in, replace everything, do just the pressure sencor, just buy a new fuel pump... lost.

Thanks for your input, I'm going to attempt to get to the fuel pump tomarrow through trunk and check everything again
