ok so i just put in a b-series motor, everything was going good; it started and i was starting the break in and drove it for about an hour and then it all of a sudden stopped putting out any spark! I checked and replaced the dizzy and checked grounds and if anyone has some good options let me know!!!! ecu fried? thanks

 

Try checking the screw inside the distributor mine came out the other day and it wouldnt start sounded like timing was off and it was the screw inside the distributor.

 

well its a brand new dizzy from distributor king and it wont spark what so ever

 

that is the only thing you change in your car?no codes in the ecu?main relay fuel pump working fine. make sure all your ground are good.

 

its a fully built ls/v and since it is a obdo to obd1 you cannot see that the ecu is throwing a code.......i have checked grounds and fuel pump was working fine i just don't have spark..........ill go through the fuses again but if anyone else has something that would be great

You can jump the ECU and still see what codes (if any) it is throwing?

 

should it throw a code if it is just not sparking? i done know much about the ecu stuff

 

still looking for some answers

 

I even switched the ecu to see what would happen but still no spark!!! what to do?

it could throw a code, you need to jump the CEL pins at the ECU so your CEL will flash on your dash, it will tell you if there are any codes. The ECU pin numbers are D4 and D21 that need to be jumped together for reading your check Engine Light.

ok thanks for the help ..................anything else anyone thinks it could be?

 

anything else?

 

bump for some more help if any...................i took off the dizzy cap and spun it over and the rotor in there spins if that means anything????

 

???

 

when you changed it over to obd0 to obd1 you had to use a obd1 distributor.

what did you end up doing to the connectors from the engine harness that plugged up to the distributor? did you end up buying a jumper, or did you un-pin the two obd0 connectors and re-pin the obd 1 connectors in? or did you solder the new ones in?
