S30Turbo

Thanks man . It is hard cause the book says plug in the analyzer and they arent any around . I came to the conclusion that it's only 3 possible things ecu,CAS, or a wire inside the harness ripped.

Thank you will try it out . Let you know my findings

I tested the coil and both + and - have Power n they switch off as supposed to. The guy that said he worked on z cara for 30 years told unplugged the CAS cable and power probled the pins for signal. We found power, ground, but e said he didnt see switched ground that supposedly comes from the ecu. I have to admit 81 l28et is a PITA

im about to buy a 81 ECU and CAS from members here.

How often do the External CAS go bad? Could a CAS go bad after just one start up? OR ECU go bad

After reading the manual and troubleshooting I found out that my ecu is not sending ground to the CAS In my 81 L28et. I went online and found replacement ecu's for $400. But my question is can I run the 82/83 ecu. I read that my harness has external dropping resistors compared to the 82/83 that has them inside the ecu. If I can do I jut disconnect the ecternal ones from the harness or do I have to require something up or open up the ecu and mess with It? I really need my car to run now for the reason that it's my daily driver.

So just re-wire that cable under the steering column to power the ecu?

I just read that I downloaded the manual. Is there a way to test the CRank angle sensor from a 81?

While I crank the engine over the ecu lights completely shuts off. Should I replace it ?

My ecu doesn't work when I crank it turns off. I need a replacement ecu. Anyone have one

I there a way to test the CAS?

I checked the ecu and there was no signal so I think the CAS isn't sending the signal to the ecu to send it to the HEI module. I still can't believe it doesn't want to start after starting right away the first time .

Ill take the CAS from you . What condition is it in

Any one have the 82-83 zx turbo dizzy with spindle And harness, ecu. My 81 CAS is acting up.

Ok thank you I will take a look at that

Ecu has power I checked that. So the CAS sends the signal to the ecu?

I have a 81 turbo engine that swapped into my 75 last week we started it for the first time. We finished all the intercooler piping today and tried to start it again but I didn't. We checked for sparked but it didn't have any. My question is why would the ecu all of sudden stop sending signal ? Im running the GM HEI.

Thank you

Can anyone tell me the specs for the distributor mounting bolts I lost mine and I need to know what are the specs so I can buy them at home depot.

I need the plug tht connects to te oil pressure sending unit I can't find it on my harness . Thank you

I do have one but Im going to put a 81 turbo distributor

Thank you for answering me Tony. I ending up buying a 81 distributor I have all the cas . An I talked to a member here and he told me to go with a gm hei. I did research and I think my car should start this coming week .

I need the Wire that goes from the coil to the harness. to complete my l28et swap. anyone thank you

Can I get pics

so i can run the l28e distributor in my l28et correct?
