Found fuel tank pressure sensor to be bad. Voltage specs between 1.3-1.7 volts, fuel tank pressure sensor never goes above .2 volts. Recommend remove and replace fuel tank pressure sensor, clear check engine light and road test the vehicle.
Remove truck bed to replace fuel tank pressure sensor
Smog inspection and certificate if pass

Lubricate and check chassis. Change oil and oil filter. Check air filter and breather filter. Check all fluid levels and tire pressures. Preform basic safety inspection. Road test vehicle.
