1985 f250 remote start

I installed a scytek astra 1000rs in my 85' f-250 diesel. It initailly would crack and once it fired it would die immediatly. I realized that the fuel shut off selanoid on the injection pump wasn't getting power when it stopped cranking. I them ran a jumper from the selanoid to the accessory wire. It now starts and runs about 5 seconds and shuts off. It then starts again and does the same thing. There is no tach in this pickup so I didn't hook up the tach wire. Is there a spot on the alternator that I could connect to? There are only two wires from the alternator, 1 that goes to the voltage regulator and the charge wire to the battery.

Take a look at page 17 of your manual. The programming options allow you to put your system into diesel mode and increase your 'tachless' crank time. This will set the starter's cranking time and set the unit to sense voltage to know the vehicle is running. You can also use any wire that increases voltage with rpm like a crank sensor or fuel injector.Installer, IT support, and FFL. I need less hobbies.

I have set it to diesel mode and have extended the cranking time. The engine is mechanicaly injected which means there is no injector wire, or tach wire that I could use. I will test the wire off the alternator to see if it increase with RPM. Any other ideas?
