I have replaced the head gaskets as I have done in several of these vans. Everything went smootly, but when I went to start it up, it will not fire. I have fuel pressure and spark, but I cannot hear the injector pulsing while it cranks over. I’ve given it a shot of starting fluid and it does fire on that, but the injectors are doing nothing. I have tried a camshaft position sensor with no change in symptoms. The PK3 key is good and there is not a security light on at all. No codes currently as I had the battery disconnected while I changed the head gaskets. Any thoughts? Thank you!
Check your fuse and wiring. I have added a wiring diagram below for reference.
