maybe I didn't post my question right... Im not getting any spark when attempting to start the car either.... my fuel pump is sending fuel to the rail... mechanic has checked for spark at the plugs and at coil.... NONE...... I have already changed the ICM, the Crank Position sensor, cam position sensor, checked all relays and fuses, and also the computer(ECM).... is there any other sensor that could give the car this problem.... Engine coolant temp sensor or MAF sensor?? Or Ignition Switch??? Please help.... this is starting to get ridiculous... Im already at $300 in parts not including labor.... PLEASE HELP

He said he replaced the ICM in his last post.
