Hello,
Yes there are a few other things you need to check. do the ground cleaning on the cylinder head. These are the grounds for the computer and if they are not doing there job no injector pulses. Same with checking or jumping the main relay which powers up the ecm. Also the ignition module on the fender is an area that the signal can get lost on its way to the ecm. I usually disconnect the plug at the dizzy and use a jumper to spike 2 of the wires together to see if I get any clicks from the injectors or hear the pump come on. If you get a signal then it is the hall effect in the dizzy if nothing happens I go through the other culprits. Good Luck, Bernie
