I bought the car in tampa. i went picked it up. put a fuel system cleaner & filled up the tank. Drove it to miami with no stops. drove it around miami for the rest of the evening & it had a lil hesistation in WOT.. Then next morning I started the car. it cranked right up. I went inside for a second & when i came back outside the car had turned off. It hasn't started since. I immeadiatly thought fuel. So I went to valve on the fuel rail & it had noo preasure.. so dropped the tank, pulled the pump, they said the pump only had 22lbs of preasure. bought & installed new pump & preasure sensor on tank.. Then noticed on the message board it read; Eng. temp. data err., Rpm data err., fuel data err., trac. err.. so i connected code scanner & it will not connect to the pcm.. I checked the pcm relay like frankie suggested I got 2 females that lite up with the key on. Swapped relay & still nothing... Now What???? PLEASE HELP!!!!!! :(
 
Dang, thats messed up! Do you get the CE light on the dash when you turn the key on? If you cannont connect to the PCM, you either have NO power or ground to the PCM or a faulty connection.

Let me know if you want wiring diagrams......
