Double click on the codes. Starting with IMM-233.

Ah hell if this is the first time in. Clear all the codes and see what comes back. Some of the codes maybe artifacts from problems long gone. Abscate has another post going where he has starting problems until he cleared a IMM related code.

I'm gravitating toward the sloppy splices on the immobilizer loom. Some of them wires are suppose to be twisted pairs all the way to the connector, to minimize Crosstalk. Also poor solder joints can degrade the communication signal.

I cannot tell from the picture, are the splices soldered and soldered well or them dam crimp connectors?

I totally missed those splices

Those won’t work. You need some rewiring help from an experienced electrician. There are twisted pair comm links on the antenna ring that need to be done right.

i didt wire them this is how i got car in two months ago,the seller had someone replace immobilizer and Antenna ring and all the parts chasing to fix car.....it never got fix so.all code are clear except the ecm-720 my Question is what VGLA output =low and blanking procedure = no
