Ok I bought an 89 bronco auto with 5.0 in it. Ran good but battery kept draining. So i went to replace the battery and somehow hooked it up backwards and now it wont start. I replaced the fuel pump relay and eec relay and starter switch as well as some wiring that was hacked up. Now the fuel pump doesnt kick on unless I use a jumper wire and its not the relay as i have used 3 new ones. usin a voltmeter i did get a reading of .50 on the map sensor and kicked the inertia switch just in case. It will start with starting fluid but then it dies right out. Seems it has to be a fuel issue right? but when jumped I get fuel to the rail but not able to run still.. Any ideas?
