1992 Ford Bronco Q&A
1992 Ford Bronco Question: Will not fire
I have not started the Bronco in a while. I was saving it for my son to drive when he comes of age. Pulled off the cover the other day, tried to start it and it would not fire. The plugs are new, the wires new, distributor new, new coil and battery and fresh gas. Fuel is getting to the injectors, pump sounds like it is priming fine, but for the first time ever, she cranks and cranks and cranks and simply will not fire. I have not yet checked the fuel pressure to see if the pump is 100%... someone mentioned the injectors could be clogged - seemed a stretch that all would be clogged. Another guy said that when one injector goes down, the computer shuts them all down?? Does anyone have any suggestions of what direction we should head in? Thank you - Lakeville
Have you verified the injectors are operating and the spark plugs are firing? - Bret Bodas
Start with the basics, i.e. check for spark at the plugs. When you crank that truck, do you have a nice yellow-blue snapping spark that will jump at least 1/2 inch? Just because the parts are new, does not mean you have spark, i.e there is an ignition module etc. Secondly, after you PROVE that you have spark, spray some fuel or carb cleaner into the throttle body and see if the engine wants to fire? If it does, then yo have a fuel delivery issue. These are 2 first basic steps I perform when I check for a crank/no start. - dandd
the year if my truck is not available but is the same as a 90 model, this thing has been giving me a fit for more then 2 1/2+ years, when i crank it, it runs fine for about 5 seconds or so, ides up...
This vehicle performs fine even when towing a 3,500 LBS trailer,on a flat road and an ambient temperature of 110 deg. f. however, when I go into the montains with an ambient temparature of over 10...
the manual states unlocking any door with the key or using the remote unlock will disarm, but my starter circut is still diabled, i.e. she turns but won't fire.
turns over but won't fire
MY 83 starts at times - and times it wont,BUT when it do'es when put in drive it stalls, please going carzy.
