- Full tank of fuel
- run (kill) switch was not tripped and is in the run position
- fuel shut off solenoid clicks on/off
- electric fuel pump runs
- Checked the spark/ ignition wires with a timing light and have spark.
- Depressed Schrader valve on fuel rail during cranking and no fuel comes out
Trying to start, it just cranks and cranks, like it has no spark or fuel.
Update (30DEC18):
removed line from fuel rail (had to get special fuel line tool at autozone $7.00) put in bucket.
Removed pick up line from gas tank after fuel shut off solenoid (so I can rule out solenoid).
Turned to run and cracked engine, no fuel picked up or comes out of fuel line.
Pulled electrical connector off fuel pump and hooked up volt meter.
Turned on to run, 12V coming to fuel pump, has 12V during initiate run position and cranking.
Isolation so far has proved the fuel pump is not working, Pulling cool fuel module and will disassemble. now to determine which electric fuel pump is not working, the low pressure or the high pressure pump, as the cool fuel module has two electric pumps.
