no spark and no fuel need help

[projectsil80]

need help. suddenly my car just lost all power to the coils and to the fuel pump. i was driving down to la then my car felt like it was losing fuel. so after a while it just totally died on me. my engine control fusible link blew so i replaced that and no it just cranks and dont start. got a new fuel pump checked all the fuses and still no diagnosis. i could just think of the ECU being messed up since it controls both fuel and spark. what do you guys think?

Could be quite a few things. Fusible links don't blow for no reason at all. Plus it might have blown again after you replaced it. Check to make sure your ecu is getting switched and constant power. Are you getting injector pulse? Is the main relay any good(if it even has one) Have you checked all the fuses under the hood and under the dash?

yeah i checked over the fuses under the hood and under the dash. they are still good. ecu is getting power. i just dont know if there is a problem with the CAS or ignitor chip.

I know people have posted the procedure for checking the cas and the ignitor before, I just can't remember where it was. If you have no fuel and no spark it may be the ecu also.

that is how you install it, but how do you trouble shoot it?
