4.3L wont fire after shut off hot until 30 minutes later. I followed schematic, and discovered a start/run relay in the circuit not listed. Once key is turned to crank, relay pulls in, but wont release, and it's not a sticking relay. If i physically open the contacts on the relay after cranking, it will start everytime. Does anybody have any info on this system? The relay sits behind the battery, and I already changed it out with no luck.
This is an Lp only system using a HEI module as well as an MSTS controller. Any help is appreciated
