5.0L (1979-1995) MustangTechnical discussions on 5.0 Liter Mustangs within. This does not include the 5.0 from the 2011 Mustang GT. That information is in the 2005-1011 section.
I have a 89 mustang wit the 5.0 HO multiport injection with a 5-speed tranny and I have no spark or fuel pressure. I think its the computer because I have replaced everything else and checked my grounds for the wiring harness but I can't find the A9L computer I need and i was told a computer out of an automatic will work it will just keep my rpms up long between shifts is that true and does anyone have one.
That sounds fair, the computer works fine...I swapped my car over to carb so no more comp. is needed. My email is his_infernal_majesty187@hotmail.com, shoot me an email with your info and we'll go from there.
