It must be because if I put fuel directly at the intake manipold it will start and continues to run fine with no problem. This is an indicative that all the electrical systems are running good. The only part that I did not change is the EHA. I even take the car to the reputable repair shop but they were not able to pin point the problem. Try to put fuel at the manipold to see if the car will start and run. If it does, all your electrical systems work. I am going to try the EHA and let you know, and if you solve your problem before mine, let us know. Good luck!
