Help us help you. By posting the year, make, model and engine near the beginning of your help request, followed by the symptoms (no start, high idle, misfire etc.) Along with any prevalent Diagnostic Trouble Codes, aka DTCs, other forum members will be able to help you get to a solution more quickly and easily!
I've replaced cap and rotor, coil, ignition module, and the pickup coil. 12 volts out of coil post. No Spark. No fuel through the injectors either . Fuses looked good.
Does CEL display for a quick second with initial key on?
if not, check for reference voltage from PCM.
What happens during crank? Does your tach move/bounce at all?
if not, check for injector pulse and do a bypass test to try and fire spark.
Depending on what you have available to test, you can test for voltage on the crank sensor to see if you get any voltage during crank.
I don't think a fuel pressure check is necessary without having spark or injector pulse.
To test injector pulse use a test light on Bat + and backprobe the control wire of the injector. During crank, the light should pulse on and off.
Making Pressure Differential Sensors (PDA Sensors) for pressure pulse diagnostics.
