The car started and then stopped. Car cranks but will not start. Connected an ODBii scanner but it cannot communicate with the ECU. When the ignition key is turned to ON the MIL lamp does not illuminate but the other lamps such as SRS do. The fuel pump works when 12V battery power is connected. Checked the fuel pump relays when the ignition key is turned to ON. The first relay engages and supplies battery power to the second relay but the second relay does not engage. Could be the ECU is not making the connection to ground. Checked the fuses and are OK. Checked the resistances on the ECU harness and all are within spec. Other than replace the ECU do you have any suggestions?

This is a bad PCM. Try to disconnect the security system first and if it still does not start then it is the PCM.

Hey Tim take a look at this, will this help ?
SUBJECT:
No Engine Crank Or No Engine Start Due To Electronic Lockup Of The WCM / SKREEM
OVERVIEW:
This bulletin involves the replacement of the Wireless Control Module (WCM), and if
equipped, the replacement of the Electric Steering Column Lock (ELV). The WCM is also
referred to as the Sentry Key Remote Entry Module (SKREEM).
MODELS:
2007
SYMPTOM/CONDITION:
The customer will experience a no engine crank AND a no engine start condition. Also, the
remote keyless entry (RKE) system will not operate. This condition may be due to an
electrostatic discharge (ESD) from the ignition key into the Wireless Control Module
(WCM), causing the WCM to electronically lockup. This condition may occur more
frequently in dry and/or cold weather conditions where a sufficient electrostatic charge is
more easily produced. This condition is corrected by the replacement of the WCM
DIAGNOSIS:
1. With the condition present (i.e. the vehicle in the no crank / no start condition), connect
the StarSCAN® scan tool to the vehicle.
2. Turn the ignition switch to the “ON” position, and power up the StarSCAN®.
3. If the WCM is electronically locked up, the StarSCAN® will display the WCM as being
“off bus”.
4. If the no crank / no start condition is present, and the WCM is “off bus”, then reset the
WCM by temporarily removing the IOD fuse (with the key out of the ignition switch),
wait for 10 seconds and then reinstall the IOD fuse.
5. With the IOD fuse reset having been performed, verify that the vehicle will now crank,
start, and run.
6. If the condition is temporarily corrected by performing the above steps, and if the part
number of the WCM is earlier than the part number of the WCM listed in the part
reference table in the Service Bulletin Parts Required Section below, then perform the
Repair Procedure.

Yes, it sounds like your solenoid is bad and staying engaged against the flywheel, you could do an amperage draw and a voltage drop test to find out for sure, but you will need an DVOM and a amp clamp. Or you could take it into an auto parts store and they will test it for free. Hope this helps.

try cleaning the connector that goes to the fuel pump, sometimes they corrode on inside. If that does not fix, test the wires feeding fuel pump with a multi meter until the condition shows itself again, if voltage drops to zero or very low then wiring problem, if voltage is unchanged with problem and fuel pump is not working and connectors are all clean, try replacement of fuel pump.
