Check the ones for the fuel pump as well. I think there's 2 for the ECU, but 1 is a memory backup. Just a little info; the ones under the dash to check are #21 its a 15 amp for the fuel pump, and #28 another 15 amp for the ignition coil. Under the hood; #1 a 15 amp for the ECM, #4 7.5 amp back up, and #3 a 40 amp for the ignition.
