my friend 90mkiii turbo has no spark

Can anybody help my friend and me out here? He was driving on freeway and his baby's just shut off on him. He check and found out that there was no spark. So we got one of his friend igniter and replace it. The engine rotates, but will not start. It took a while before it started and was idiling roughly. He took it for a test drive.[img]images/icons/icon9.gif[/img] After that, the EFI 15A fuse blown so he put in another one and it did the same thing. After about the 5th one we stop and check all the wire from the engine to the ECU. Nothing was wrong then we replace the coil pack and the cam position sensor. Before installing the CPS we also set the timing and line up the CPS to correct mark and place, but still no spark. Jump the code. It 14 which is Ignition signal. So we are out of ideas. We also check and use my 91 mkiii turbo as a sample of where everything are suppose to be at. Can anybody help us out? [img]images/icons/icon11.gif[/img] Thank you

it seems you have a short to ground probably on the fuel pump circuit, check for short to ground at the fuel pump relay.http://www.cygnusx1.net/supra/library/TSRM/d/D_04.html
