Ya check your manual and proper voltage thats all I can tell you this is really the only way to do it and check for a short in your wiring on the chassis side

check voltage on both side (dizzy and ecu) and it gives me a 375. tried using another dizzy same thing. tried the ecu on my friends car same it tested good dont.

Re: I GOT A CODE 4 ON MY PR3 ECU
 

voltage or resistance?

Re: I GOT A CODE 4 ON MY PR3 ECU
 

ohms

Re: I GOT A CODE 4 ON MY PR3 ECU
 

Which is resistence.

Re: I GOT A CODE 4 ON MY PR3 ECU
 

resistance. it was 388

check the wires in the actual distributor plug to see if they're backing out or anything. ensure that full contact is being made. barring that, you mentioned that you tried the ecu in your friends car, but I couldn't make out what the rest of that said.

the ecu tested fine? or it gave the same problem?

go over your grounds again, and make sure all pins are making good contact.
