			 Hi guys,  
		
	
		
		
		
		
		
		
		
		
		
	
	I just installed a 91 5.0 and all engine controls into a non-ford car ( an Rx-7 ) . This is going to be a smog-legal project, so i have to get it right. The car is running and I got the check engine light working but the fuel pump error code 87 comes up and keeps the cel light on, so I have to clear that. (code 87 (oc): FP relay circuit failure- suspect inertia switch, fusible link, FP relay. ) I did not use the ford relay when wiring up the rx-7, I used the stock Mazda set-up. I'm getting strange reading of 6-7 volts on pin 19 of the ecu even though the wire is cut . I think I may get rid of the code by applying 12v to pin 19, but thought I'd run this by you first, as I don't want to blow up the ecu . Here is a copy of the schematic : http://pg.photos.yahoo.com/ph/sgcpa1...?.dir=/c324scd Sorry for the lack of detail on the picture, I can e-mail a better diagram to you if your interested . Thanks for any help.  |

			 Tell me what wire color it is and I'll go put my meter on it...pin 19 on the ecu...I'll check the voltage for ya.

			It's dark green and yellow. You can also catch that wire at c213 the green connector next to the ecu here is a url that wil work better http://webpages.charter.net/kgoldste.../fuelpump4.jpg Last edited by v8-7; 07-16-2006 at 11:11 PM..  |
