fishman517 Posted June 29, 2009 Report Share Posted June 29, 2009 I have a 89 it runs great except it has a gremlin. It will start,run smooth and sometimes it will just quit. Sometimes it will restart,then their is the other times and it will not start. I put a fuel pressure guage on it and the pressure stays at 39psi,I hooked a timing light to each cylinder and they all have spark,I checked for 12 volt supply to the injectors,I changed ignition module,ecm,crank sensor,cleaned and ohmed out the grounds,looked for bad connections or rub throughs, I AM OUT OF IDEAS HELP ME PLEASE! If you have experienced anything like this tell me your story. thank-you Quote Link to comment Share on other sites More sharing options...
