Several weeks back I was driving my Z28 around. I was pulling away from a stop light, not aggressive acceleration or anything. It hesitated, then flat out died on me. I pulled over in a parking lot and was able to get the engine to catch for a few seconds before dying again. I saw a little smoke coming from the throttle body. It would not start up after that. I checked the oil and it doesn't have any coolant or metal shavings in. The coolant level has not dropped at all since sitting or the time of the dying. I can't afford to tow it to a shop and then pay them to diagnosis it. I have a sneaking suspicion it is the distributor. When I had been troubleshooting a previous coolant leak, coolant and water had been dripping all over the dist. The engine will turn over if I hit the ignition, but it won't catch. I am planning on doing a compression test. Anyway to know the timing chain didn't break or jump?

 

sounds like an opti to me. dizzys dont like water on these.

 

Totally sounds like it is ignition related. Especially since you saw the t-body burp some smoke. That is a good indication of an ignition/timing issue- which your opti is responsible for. Check for spark and fuel pressure to the rail- both easy to do and go from there. The timing chain is very strong on these engines and a failure is extremely rare. Since you said that coolant got in that area I would go with craby and suspect a pissed opti. Good luck

 

Update! I got my new opti installed and it is still not starting up. I tested to make sure I am getting spark and I can hear the fuel pump engaging when the key is turned forward. I am assuming there is only one way that opti can go on because of the keyed dowel. Any suggestions at this point?

 

spray some gas in the tb and see if she will run. if u have noid lights check to see if your injectors are getting the command to shoot the fuel.

 

also is your harness from the opti good? craby just helped me with a question bout that lol

 

I rented some noid lights from Autozone and hooked up the one to an injector harness...and nothing. No lights blinked. I tried it on another harness and the same thing. My battery is dying from the past weeks of me turning it over, but I should still see a light. Is there a fuse or a relay that I should check that might cause this?

 

if yours is like mine, should be two fuses it the powerbox on the diverside fenderwell that go to your injectors. one for one side and one for the other. check em.

 

The fuses look good. I checked all the fuses and the looked okay.

 

u are going to need to check to see if there is juice getting to the fuses. im seeing in the book it could be pass key decoder modual. are u setting a trouble code 46?
