Lh2.2 240 no injector pulse

From what I remember, the trigger signal is sent from the Chrysler ignition module. Dodgy biodegradable engine wiring can be a big part of this too (improved in late 1988). The part of the wiring harness that contains the wires runs under the front of the engine and up to a couple of plugs under the inlet manifold, the main plugs at the firewall, plus a connection to the coil on the inner guard. IIRC you can jury rig a signal from other sources. There are wiring diagrams online.

Make sure the bulkhead plug is seated properly. The rubber goes brittle and you think you've connected it but the pins can back out.

I've had this exact issue with my 240 way back in 2014. Had spark, pumps primed when I turned the dizzy. Testing with a multimeter found I had no 12v to the injectors. Looked at a wiring diagram and my issue turned out to be the inside of that plug had corroded and the injector 12v wire had backed out.

Fantastic news man! Congratulations and good luck on the big day!

Slowbrick I'm having the exact same issue, when you say bulkhead are you referring to the connector to the ecu or ecm? Or referring to something in the engine bay/firewall?

sloth do you have a photo of the claimed "bulkhead" that you had to clean? Im having the exact same issue on a 88 240. did a head gasket/timing belt and have fuel spark and air but no fuel to injectors and I'm getting power to them,

Check the fuel injection fuse by the battery.

ramrod replaced the fuse but the fuse holder isn’t in great shape so I’m going to swap that out today and see what that does. Still unsure of what the “bulkhead connector” is. The grey connector on the firewall? He mentioned passenger side, and the grey bulkhead sits about center if not closer to driver side. So unsure of where it is.

Both of those grey 'bulkhead' connectors are a known problem, yes.
