Hi, I am new and not sure if this is the right place to post but I am at a loss. I bought an 89 bronco XLT 351w 5.8 about a year ago. Before the purchase it ran but needed a jump to get going, it idled high so I figured it needed a little TLC. However on the day I picked it up it stopped starting even with a jump so it got trailered home. I bought a new battery and fucked up, I put it in backwards. I float charged the old battery, replaced the starter solenoid and positive cable and terminal (both cables were black hence my idiot mistake) as well as the starter. The lights all work, door chime and gauges come on, but again crank and no start. This time I notice the fuel pumps aren't making noise. I replaced the spark plugs, air filter, crankcase filter (hose was disconnected so I assumed that is where the high idle came from), low pressure fuel pump, high pressure fuel pump, fuel filter, fuel relay. Tried again, no pressure at the rail but I can hear them come on. Next fuel regulator and discovered the fuel accumulater but can't find a replacement anywhere so I did a bypass. Now there is pressure at the rail but still crank and no start. It does start on starter fluid. I checked all the fuses under the dash and they all look good, i swapped the new relay over to the EEC relay but no change. I don't know if I can check codes because I have been disconnecting the battery to float charge it while I'm not working on it. Is this an ECU issue or other electrical something? How would I test that? The previous owner told me that sometimes the steering wheel had to be wiggled to start it. Any help would be extremely appreciated, thanks!
