Hi, I have an 1992 acura legend ls. About two years bak I was on the highway going about 75, my front right tire blew and it tore up my fender and was really rough until I could come to a stop. Got the spare tire on. Started the car, and it the engine was shaking. Acceleration was bad and the check engine light was on. After driving it bak and forth to the shop, the acceleration got worst and it wouldnt stay started unless you had your foot on the pedal. The car also would die. Then the car wouldnt start at all. I was told it was my crankshaft position sensor. I removed that it was melted and looked bad. Replaced it and now my car still doesnt start. Any ideas of what it could be?

When the CEL comes on, it means an error in the engine management system as been detected and you need to retrieve the trouble code to understand what had gone wrong.

The above link explains how to go about checking for trouble codes.

As to the non starting, you need to verify what is missing, ignition sparks, fuel or mechanical fault.

You do not need any scan tool as pre-OBD-II models has a self diagnostic system that allows you to retrieve the trouble codes with the aid of a jumper wire. Click the first link to get an idea how to retrieve the trouble codes.

You should get the trouble code to understand the problem first before attempting to replace anything.

Speculating and guessing does not work as it is like looking for a needle in a haystack.

It could be anything from low engine compression to a bad sensor.

Thanx so much. Youve really helped. THe jumper wires I would get from like an autozone. If you were in my shoes would you just get rid of the car? Cause I kno they can be expensive to maintain

Ive actually just removed the panel and I see alot of different little computers but I have no idea which one is the pcm and how to even hook the jumper wires up to it. Any way you could post a picture or tell me via writing how to do it?

You can use a paper clip to act as jumper. Bend the clips and insert each end to one of the terminals to short the connector and you are ready to go.

Vehicle is rather expensive to maintain but if it has minimal problem, it is worthwhile to keep it.

Also ive been told to take out the computer and let it sit for like 10 minutes then plug it bak in and it may start. A friend had the same exact thing happen and he took out the computer and put it bak in and it cranked fine. Should I try that first?

No, if the computer is disconnected, you would lose the trouble codes and if it can't staart, you would not be able to know where to start looking.
