Sounds to me like you opened a can of worms that you are not equipped/qualified to deal with. To begin with, doing an engine change the way you did it is illegal. It is OK to put the newer motor in the older vehicle, but it is against federal law to put the older engine into the newer vehicle. REFERENCE: EPA ENGINE SWAP FACT SHEET
With all that said, if you want to do a swap like that, it is necessary to also swap wiring harnesses and computer modules (among several other components) if you expect it to work.
No ,I haven't Fixed my problem, I'm still awaiting solutions and feed back from helpful people that may have went thru the same problem. My Wife is out of work so it's a little tough on me right now. I want to correct the problem myself.
One place to start, Spark to ignition and power fuel are two different sources. Unless they both work off the same fuse. The fuel pump needs power to run the fuel pump, Ignition needs spark to fire the engine. Check your fuses because in my opinion it is odd that they both went out at same time. Good Luck
