So my 85 Volvo 240 quit. it did start again and make it home then Quit.
*this car was stored for years I put 2 new fuel pumps on
*installed new fuel tank
*changed plugs cap button etc
drove car for 1 month now this I have done some trouble shooting but seem to have no ground for the Injectors... There is a 12vsupply for them. I need to know if the ignition module 1346107 (looks like a Chrysler part) could play a part in this?
I have remove the engine harness untaped it and used a ohm meter between all wires looking for a short. couldn't find any.....harness is now taped and reinstalled. SO CALLING ALL 240 1985 on this Jetronic problem please!
No start 85 240gl

The Chrysler ignition has a white distributor cap.
Check the fuel pressure at the fuel rail on top the engine. I think should be 42 PSI? Get some new fuel injector seals ready and then remove the fuel rail and put cups made from cut off clear water bottles to check for spray pattern and uniform flow from each injector. They may need to be cleaned.
Did it run fine for the month or were there problems?
Do you have a manual with electrical schematic?
A timing light on the coil wire will indicate if you have uniform spark to all cylinders.

*I have fuel pressure
*yes have a Schematic
*I have good spark
****I do not have a Ground to trigger the injectors. as there is a constant +power to the injectors with ignition key on then there has to be a trigger from something. I have plugged in a noid to to the injector plug and NO light when cranking. pretty sure there's no crank sensor.?? on the 85 Jetronic .....so the engine has to know when to inject........so had to wonder i a trigger was made through the ignition box part 1346107

I have a Bentley Manual for these Volvos.
I need to comfirm some things. Do you have the Jetronic mechanical fuel injector system with fuel distributor? I think these have continuous fuel injection.
Jetronic Fuel pressure looks to need 75 to 84psi to the fuel distributor.
If you have the LH fuel injection system then you have injectors with both fuel and electrical connectors as you have mentioned. These systems need 36 psi fuel to the fuel rain.
These years 240s had bad engine wire harness insulation and would develop electrical shorts. You may have missed the problem area.
Have you checked the main fuel injection fuses and relay?
Also there is a required RPM signal for fuel delivery.

ok its the LH fuel injection I was aware of the bio degradable Harnesses they seemed to mostly go bad close to the firewall harness plug.my harness looked solid, there is fuel at the rail there has to be a Trigger for the ground. So where does the RPM get a signal ??

so from the schematic im looking at the 1346107 ignition module pin 1 sends a signal to pin 8 injector grounds. will see wont get back at it for several days.

I went looking again for information on the RPM sensor. The Bentley manual says the RPM signal comes from the ignition system.

yes it Im pretty sure pin ! on the ignition module goes to pin 8 on the ECM.I am going to ohm out the wires and conductors from the ignition controller before buying another.......they are around $300 so want to be sure

thanks for this.... there is a attachment from which I learned the 10 pin male plug on the ignition unit has sleeves pushed over each connector pin which im going to remove and check for corrosion
