i have a 1988 bronco xlt with a 5.0

it just died on me one morning. i have no spark and no power to fuel pumps. i changed the plugs, wires, cap, rotor, coil, ignition control module, fuel pump relay. finally i called someone to come and take a look at it, they said the coil i got was bad and if that didnt fix the problem then i needed a new computer. i changed the coil again and changed the computer but still no luck. i'm out of ideas. when i pull my coil wire off of the cap and put a plug in it i only get one yellow spark when i release the key. my fuel pump isnt getting power. i can jump the relay and hear my fuel pump kick on so i know the fuel pump is o.k. i know at this point it has to be something small because ive changed all the big stuff.

any help would be greatly appreciated:banghead

i havent taken it wheelling in a long time. i just go to and from work. all street. i started it in the morning and let it warm up then backed out of my driveway and got about two car lengths when she died stone cold dead. it took me awhile to push the damn thing back into my driveway by myself.

yes i did jump the relay and the fuel pump kicked on and yes when i did this i had fuel pressure, but it didnt matter because i have no spark.

i did have the ignition control module tested and it failed, but i changed that with no luck. i do have a code reader. i used it when this first happened and all i got was "fuel pump relay circuit failure" code. the next time i tried to use it i got no codes. the light just stays on.

i will have to try to locate the ground wire to the computer this weekend.


if the ignition switch is bad will the engine roll over?

so far i can tell you that the coil was bad and so was the ignition control module,i had both tested. i just dont see how three or more things can fail at the same time.:banghead

thank you all very much for your input.

saturday i am going to change the ignition switch and try to locate the ground wire for the computer. i'll let you know if it works.

well it turns out the fusable link going to the eec relay was blown. i jumped it off the fuel pump relay and the damn thing started right up. i cant find the actual fusable link, so i just ran a new wire from the battery to the relay. will this be o.k.?
