Tody SUCKED!! I was driving down the road and my check eng light came on. The car ran but lost power. I got home checked the code MAF sensor poped up. OK I put a new sensor on, took it for a ride. Not bad at first then bam the light came back on same truble. Got home put the jummper wire back in the light flashed a few times then stayed lit. I took the jumper out tried to start BAM no spark. Did I short something out???
changed the coil still no spark?? HELP!

 

If your ECM will not read out trouble codes, the ECM battery or ignition fuses may be blown, the ECM ground wire(s) may be open, the ECM may be defective, or the diagnostic mode terminal in the ALDL connector may not be properly grounded. I'd start by checking the fuses, if it won't fire.
