had the key cut and programmed. . Car still wont start.the key to the car.Now when I try to start the car it almost starts but immediately died right after. I have installed a new battery, starter, pugs and coils and fule pump assembly in the last 8 weeks. I dont have a clue what to try now.Help me please.

 

Check MAF, maybe needs a cleaning. Should have the car scanned with an OBD. See what codes are being pulled. It could be a number of things. Scanning will save you time & money.
I had similar problems. My 100 dollar OBD from AUTOZONE saved me a lot of money.

 

Its for sure not the security system still causing issues?

 

Scanner will indicate alarm (imobiliser) problems for sure. It happened to me about 10 years ago, Unfortunetly every mechanic I spoke too said I needed tp take it to dealership. They towed it, fixed it at a cost over $500.00. BUNCH OF CROOKS!
