Hello everyone I'm new in this forum. I decided to become a member hoping someone has gone thru the same situation that's happening to me. I started my project with an original mustang coupe 4 cylinders and at the same time I bought a running 99 cobra with only 76,000 miles. I swapped everything from he cobra to the coupe. Motor trans ,dash, irs, ECM harness .ever single wire from the cobra to make it smog legal even the dash and ac unit. Went to start it when I put the key in the anti theft does not even flash it won't even come on. When you open he key there's no power to the cluster and fuel pump won't come on. I rechecked all my work every single ground wire all the fuses are fine. And when you turn the key on I don't have any power on the cluster and the digital odemeter doesn't even display the miles on the car, its blank. For the 3rd time I pulled the dash and rechecked all he connectors , all grounds and everything is plugged . Basically I redid my car 3 times to check for errors and can't find a problem. It sucks because my 99 cobra was running now it doesn't run. Please if any of you have gone thru this problem please please help. Any suggestion will help and it will be appreciated. It seems like there's no communication somewhere around anti theft and cluster. Thank you .
