Electrical Issues.
Soo the car won't start.
Throws App sensor code, a Throttle position high and low voltage code, The IC pump stays on all the time whether the key is in the ignition or not, and the fuel pump relay doesn't turn on when the key is turned on.
Its not the fuel pump relay itself/ Its not the ignition switch and i checked all the grounds.
Somehow my pcm is getting constant ignition power, the IC pump shuts of if shut off in hpt. the fuel pump is still not turning on, where could the short be between the vcm and the ignition signal?
[PCM] P0230 - Fuel Pump Relay Control Circuit (SES) (Pending) (History) (Current) (Immature)
[PCM] P0443 - EVAP Purge Solenoid Valve 1 Control CKT (Pending) (Old) (Current) (Immature)
[PCM] P2101 - Throttle Actuator Control Motor Circuit Range/Performance (SES) (Pending) (History) (Current) (Immature)
[PCM] P1682 - Driver 5 Line 2 (Pending) (History) (Current) (Immature)
[PCM] P2610 - ECM/PCM Internal Engine Off Timer Performance (SES) (Pending) (Old) (History) (Current) (Immature)

Here's a copy/paste of what is on SI about the P2610:
P2610
• The ECM is powered down.
• The intake air temperature is between -40 to +125°C (-40 to +257°F).
• DTC P2610 runs once per ignition cycle.
Conditions for Setting the DTCs
The ECM detects an internal failure or incomplete programming for more than 10 seconds.
Mentioning what kind of car you have might help people try and help you.

If youve been tuning it I would try reloading a know good tune,maybe the pcm is corupted and reloading may fix it.
Another thing is to check the pcm connectors,could be loose.
Pull and reseat all relays in the fuse box,concentrate on the crank,start relays could be loose due to whell hop
Etc.

Did you put the motor in with the harnesses installed,possile pinched wire,
Take a good look at the harnesses where they come out of the fire wall for any mark indicating that
It might of been squished.
Then take the harness apart to take a good look.

make sure the throttle body connector is properly installed el angelito. for the OP I would suggest removing the fuse box and checking the connectors. Also, making sure all the correct connectors are made, the coil paks and the cps are interchangeable. The PCM pins are an issue as well, they can wear out at the connector so be cautious.
