someon26 Posted June 1, 2004 Share Posted June 1, 2004 Hello I have just bought 3 subarus for 50$(86 and two 87 GL-10)the 86 is in great shape but the wiring harness and the drivers side under the front fender burnt, the guy tryed ti fix it but had no clue on what he was doing. I looked at it and put new wires in, but the car still wont run. if i put gas in the trottle body and it runs, tryed changing the fuel prump and still with not run. Just like to know if anybody would have a clue on what i can check next? or if somebody has a wiring diagram. Thanks in advance Quote Link to comment Share on other sites More sharing options...
subiemech85 Posted June 1, 2004 Share Posted June 1, 2004 what body style and engine do you have? could you be more specific as to the problems, and damage Quote Link to comment Share on other sites More sharing options...
subyrally Posted June 1, 2004 Share Posted June 1, 2004 check the fuel lines the run up the drivers side from the rear to the front, up the side of the kick panel, and out the firewall. if the wiring got burned, the line might have been damaged. just a thought though.

WJM Posted June 1, 2004 Share Posted June 1, 2004 3 subes for $50...what a steal! My vote is that some wiring is still crossed up from the burning and idiot incidents. Quote Link to comment Share on other sites More sharing options...
someon26 Posted June 1, 2004 Author Share Posted June 1, 2004 well it is a wagon mpfi turbo. everything in the car works, just got nothing at the injectors. I have been looking at this now for about 3 days and I am lost. I am a mechanic by trade but on hevy equipment and this mpfi is new to me. lol.

someon26 Posted June 1, 2004 Author Share Posted June 1, 2004 btw the old harness piece was in the car and it was just a melted chunk of wire. The guy who had the car before has been trying to get it going for the last year Quote Link to comment Share on other sites More sharing options...
Cougar Posted June 2, 2004 Share Posted June 2, 2004 To see if the fuel pump is working try cranking the engine for a second and then turn the key to 'off'. Then turn the key to just the 'on' position and you should hear a slight hum from the fuel pump for about a second. This will tell you that the pump is getting voltage and most likely working ok.

garner Posted June 2, 2004 Share Posted June 2, 2004 hey there Someon26, I have no answers for you right now but I'm having a similar problem with my swap. My saga: http://www.ultimatesubaru.org/forum/showthread.php?t=16856 I've got the same deal, everything works except the injectors.... So, check this out: The injectors don't click while under fuel pressure but once I disconect the fuel line at the injector, they will click.... My current theory is that my pressure regulator is bad (so is my spare) and the injectors can't open against the high (65psi) pressure....??? Is this possible?? In terms of wiring, check ALL of your grounds. Follow every ground out of the computer and all the little grounds that split off the harness.

someon26 Posted June 6, 2004 Author Share Posted June 6, 2004 well been working on this car now for 2 days and still cant get it to run, everthing works just having probs with the fuel system, been reading a few books and still cant fig out the injector system in this car. Is there any way of testing the MPFI computer?? And also wandering if it is a big job to go from MPFI to a throttle body injection system??
