My bronco will not stay running

[Goorange]

I have a 91 Bronco with a 302 that was from a late 80's early 90's Mustang. It is fuel injected. The bronco was parked for about a year and upon trying to get it going again it would not fire. The determination was that the distributor brain was bad, which it was but in order to replace that you have to pull the distributor. After putting it back in I took it to a local garage to get it running and set the timing. The mechanic said that the plug wires were in the wrong order and that the distributor was in the right place( what are the chances we set it back in in exactly the right place?!) and that when he fired it up it would run for a very short time really rough and then die. He then told me that he thought a valve was bad or a rocker arm was broken or bent. Well the thing is, Everything was fine when it was parked and the only thing that was touched after the fact was that distributor So I believe he put the spark plugs in the order that a bronco calls for and not a mustang and that it still just needs to be timed........Does anyone agree or what should I do?

i do agree with u whenever u do a motor swap like that u have to put the wires on the way that that motor calls for not that vehical. if they were in the 91 bronco fireing order that wont work unless the firein order is the same i dont know if it is or isnt so i cant tell u there and if its not timed just right then it will do exactly to the tee what u said it is doing,trust me i know ive done it before. and also i would be willing to bet that u did not put the distributor in the right spot now belive me im not callin u a da ive done the samething before so dont feel bad and also that machanic probably just wants more money bc correct me if im wrong guys but when u bend a rod or a valve is busted(which ive never heard done) then it would just be missin on that cylinder,which yes that would mess with ur timing but u could still get it close enough to where it would run.so i think ur best bet would be to inspect the wires,check the distributor then go from there,one thing ive learned is start with the simplest thing then work ur way to the stuff no one wants to do lol.

I figured as much, and I realize you aren't insulting me...lol My friends actually did the distributor brain and they told me that they didn't put it back correctly. So like I figured if he set the timing it would have been fine but I don't think he even checked it, he just eye balled it and obviously that is not possible to do. At the same time my bronc is kind of a mess under the hood as far as the wiring harness goes. Don't get me wrong there is absolutely nothing wrong with the harness but it is cut and patched and I think he took one look and said F this...lol Because he has actually been really good to me in the past so I am gonna get it home and mess with it myself....I am sure I will be posting again soon...lol Thank you very much though for confirming my suspisions

The firing order for 1987-1993 5.0Ls is 1-5-4-2-6-3-7-8. If #7 and #8, or #2 and #4 spark plug wires are routed next to each other at the separation bracket, an induction crossfire condition can occur.

To eliminate the possibility of the coil wire becoming disconnected, route the coil wire under the spark plug wires at the distributor cap.
