K9WAGON Posted May 9, 2012 Share Posted May 9, 2012 turn the key on, and most of the lights come on, all except for the check engine light. If I plug either of the two blue wires for the test mode, nothing happens. fuel pump doesn't run, unless I give it power. injectors don't fire no spark either bad ecu?

lmdew Posted May 10, 2012 Share Posted May 10, 2012 ECU are pretty good. I'd start by checking all of the battery connections, grounds and fuses! Quote Link to comment Share on other sites More sharing options...
K9WAGON Posted May 11, 2012 Author Share Posted May 11, 2012 all fuses checked, incidentally it had a less then steller body ground, but fixing that solved none of the issue.. is there w way to test the ecu at all? shouldn't plugging the test connector in make it do something?
