I have contacted FAST the first time about 9 months ago about a EZ EFI 1.0 that is not working. First you get a lot of contact from a tech asking you a bunch of details. then sudenly all communication stops and you are left in the dark. After asking for help again you get another tech and the whole story starts over again untill all communication stops again. It seems that FAST don't know what the problem is and try to ignore it. Here is a discription of the problem. This system was first installed in a 70 Chevelle on a 350 motor and worked perfect. The motor was sold with everything on it and transplanted into a 85 El Camino. All the parts in the system apart from the fuel tank are the same and what I have found is that the fuel pressure drops to 0 PSI under acceleration. Cruising the pressure stays arround 45 PSI. Offcourse the motor starts misfiring as it is not getting any fuel. As I said before I have tried to get help and info from FAST for the last 9 months and keep being put in the dark. I hope that someone can help me out here as I'm about ready to chuck everything in the trash and put a carb back. And, I'm bassed in Belgium so not so easy to send equipment back for checking or repair.
