also if you have a fuse blown it will do the same.

Re: (NAS_OCSICNARF)

i dont THINK it was the relay because my uncle said so. but he doesnt know as much as you guys so thats why i poped the question. i thought its maybe the ecu because along with the car not having a spark my fuel pump isnt turning on. so a combination of probelms was my thought of the ecu. i read your link and it said how the main relay controls the ecu and fuel pump, so seems to me that its the main relay.

my car did the same thing. i thought it was the ECU then i realized it was recognizing codes... if your car is recognizing codes your ECU is fine.. try the main relay or get the codes your car is throwing

check for any loose wires in your MSD setup. Also check if all the pins are connected in your distributor harness.
