No spark?

[rangerbronco288]

SO the other day when windchills were -25 when i was leaving work my truck just shut off and wouldnt start so i just left it there. I was up there yesterday when i crank it over i can smell feul so im pretty sure its not a fuel issue. I take out a plug ground it and of course no spark. So what do you guys think coil? Ignition module? Luckily i just put the trans in the bronco



Thanks

I'd say the coil

 

[rangerbronco288]

yea i will probably just switch the coil off my b2 and see it it starts

What year?? 2.9?
if 1st gen or 2nd gen. then it could be the ignition module,aka TFI.
or the ignition relay on the passanger side inside fender.

the 2.9 only went from '86 to '92, if you look in rangerbronco288 's sig he lists his '88 ranger as having no spark. If you have no spark it could be one of two things right off, it could be the ignition module (likely) or the coil. Pulling codes might point you in a more specific direction. Instructions for pulling codes are in the tech library.

Thanks for all of your input guys i have a known good ignition module from an old engine ill probably tow it into the shop at work and see if i cant get it running

it could also be the computer. mine went out in my bronco and there was no spark. try switching the computers.

when you crank it over check and see if you are receiving ground signal through the green wire with yellow stripe that hooks up to the coil. also with the key in the run position check and see if you are getting power the the red wire that plugs nto the coil. do the latter first by using a 1156 bulb and grounding it to the block and running a wire from the red wire that plugs into the coil to the + connection on the light. with the key on if you are getting power than the light will illuminate. if it does (using the same light) connect the green with yellow wire that goes to the coil to the - light and the red wire to the + contact on the light and have someone crank her over. if you get the on/off over and over than your coil is bad. if you are not getting power to the red wire on the coil when doing the block contact test (referred to earlier) than you either have a bad bad wire. This red wire only hooks between the ignition switch, the ignition coil, and to the tfi module. a defective wire here usually does not occur. the only other thing that would be wrong there is the ignition switch itself. If you get power there and no - signal on the green wire with yellow stripe than you have
a.) a shorted green with yellow stripe wire. this wire runs between the coil and the tfi module only. do the same test on that wire at the tfi module side and if you get on/off light when cranking her over than you know you have a short and only need to replace the wire. again it only runs between the coil and tfi module.
b.) a defective tfi module
c.) a defective pickup module (under the distributor cap)
d.) a short on the 8 to 9 inch wire set that plugs into the computer and tfi module. it cant be anywhere else because your computer is sending fuel into the system. if the computer is defective you will not get fuel.
If you get - and + to the 2 wires running to the coil plug than you deffinately have a bad coil. These test are easy and alot less expensive than having a garage doing it for you.
