 Bronco is dead.So a few weeks ago I get home from work and everything is hunky dori. I go out the next morning to start it up and no fuel pump. All other electrical is working that is non efi related. I checked fuel pump, checked the fuses and rearranged the relays to see if one of them is bad. Still nothing. I then hook up my code reader and it just buzzes(or constant light, does not go into code checking program). Could my efi be fried and or any tips as what else to check.
Stock 302 with reworked 1990 mustang harness. Ran well for 8 or so months. Most electrics(pump, ecu, etc) less than a year old. _________________ 71' bronco, np435 w/trailbanger, 302 efi, 35" KM3 on 17x9 Fuel Anza, warn xd9000i, cage arms, 5" lift Last edited by B.O.B. on Sun Aug 10, 2014 9:43 am, edited 1 time in total. |

Re: Bronco is dead. Check for power and grounds at the PCM first. If all is good crack the PCM open and look for leaking capacitors.

Re: Bronco is dead. Looks like the capacitors on the board are fried. Anybody know someone that can fix this or am I going to have to bite the big one and front for a new ECM . Popped n Kirks and it fired right up. ( thanks again Kirk).
