Celebrity 2.5L Engine Won’t Start
Question:
I have a problem. – 86 Celebrity 2.5L
Car will crank but not start. While swapping battery and connecting
positive cable first I heard a popping sound by the right firewall. I
finished hooking up the battery and tried to start the car:
1. Car would crank but won’t start
2. Checked for spark wth timing light – no start
3. tried to pull codes (with paper clip) old fashion type – light would not
flash
4. radio fuse blew, all others ok
5. Could it be the computer? If not what could it be?
6. Is there a way out can check the computer – or just buy one from a junk
yard”
Answer:
It could be the computer, or a fusible link in the wiring harness. A fusible link is basically an inline fuse, that is not replacable. You would have to find the link in the harnas and replace it. Sometimes there are fuses/relays in the engine compartment also, but that is more common on foreign cars. To really diagnose the issue, you need a multi-meter, and a good repair manual with wiring schematics. You need to see if the computer is getting power, and test some of the outputs to see if it’s working.
You can buy computers out of a junkyard, and this may be an easy way to diagnose your problem without spending too much time or money. (depending on the cost of the computer) I would think you should be able to get the computer from a junkyard for less than $150. Check out www.car-part.com to search junkyard inventories.
