AI Coupe Posted June 25, 2007 Report Share Posted June 25, 2007 Having a problem with my kids 89 GT fuel injection system. Just reinstalled motor after oil pump and shaft replacement and no fuel to the rails, AND no spark. Originally had no fuel pump power but have bypassed the relay and now OK. I have been all over the connections, grounds and distributor module, all are OK. Motor turns over fine, but won't fire. If anyone has any ideas please post 'em... if anyone knows a shop that specializes in electrical problems with Fox body Mustangs please let me know. Thanks, Ron Quote Link to comment Share on other sites More sharing options...
Dave1647545494 Posted June 25, 2007 Report Share Posted June 25, 2007 you have no power to the fuel pump either? did you check for power at the eec relay (next to the computer) might also try swapping out the computer for known good one http://www.veryuseful.com/mustang/tech/engine/images/88-91_5.0_EEC_Wiring_Diagram.gif Quote Link to comment Share on other sites More sharing options...

AI Coupe Posted June 25, 2007 Author Report Share Posted June 25, 2007 Swapped distributors, probably should swap computers. Hope I don't have to go the Painless route (again). More later... Quote Link to comment Share on other sites More sharing options...
