Bronco87-90
New member
Greetings, New to Broncos. I have two of them in the family now. An 87 and a 90. The 87 has been a challenge since we bough it. It ran perfectly fine during the test drive. About a month after we got it home it started running like it was only hitting on a couple cylinders. We changed the plugs, and it didn't do anything for us. To it to a mechanic, and they ended up replacing the EEC. After that, we had issues with the fuel pump running continuously, but it wouldn't start. Mostly on rainy days. Eventually the fuel pump quit running continuously. Ran great for a while, Last Saturday my son pulled into his parking spot and it died before he could turn it off. Then it wouldn't start. Went back few hours later it started fine. We drove it about a mile and it died. It started again and went about 1/2 mile then died. No stutter, or warning, just no longer running. Any thoughts on what we should be looking at? Forgot to mention, there for a while, it'd run fine, but wouldn't start if the engine was warm. We've replaced the fuel pump under the driver seat, and put the right size battery in it. We've replaced the starter. Bottom line is it's not consistent when it won't start, or when it'll die. Thoughts? Thanks, Paul
