I got new pcm to ???? Was it programmed ? Dealer !
checked senors 5 an 7 are the ones that ive found to be the promblem ?????????? What are sensors 5 & 7 ?
2000 PCED On Board Diagnostics II
SECTION 5: Pinpoint Tests
Procedure revision date: 01/07/2003
A: No Start
A: Introduction
A1 CHECK PASSIVE ANTI-THEFT SYSTEM (SECURILOCK)
Note: This vehicle may have an anti-theft system, which may be activated, causing the no start condition. Verify by viewing anti-theft indicator light on instrument panel or a Diagnostic Trouble Code (DTC P1260) may be present.
Is the system activated?
Yes
No
REFER to Electrical Anti-Theft, Section 419-01 in the Workshop Manual for diagnosis and testing.
GO to A2 .
A2 ATTEMPT TO CRANK ENGINE
NOTE: Verify inertia fuel shutoff (IFS) switch is set (button pushed in). Refer to Owner Guide for location. Does engine crank?
Yes
No
GO to A3 .
REFER to the Starting Systems, Section 303-06 in the Workshop Manual.
A3 IDENTIFY TYPE OF NO START
NOTE: The purpose of this Test Step is to identify intermittent No Starts in order to guide the technician to the proper repair procedure. Does the vehicle start now?
Yes
No
Vehicle is an intermittent No Start. GO to Z2 .
Natural gas vehicles:
KEY OFF. GO to HA47 .
All others:
KEY OFF. GO to A4 .
A4 CHECK VREF VOLTAGE TO THROTTLE POSITION (TP) SENSOR
Is voltage between 4.0 and 6.0 volts?
Yes
No
KEY OFF. RECONNECT TP sensor. GO to A5 .
KEY OFF. GO to C1 .
A5 CHECK FEPS CIRCUIT FOR SHORT TO POWER IN HARNESS
Is voltage greater than 9.0 volts?
Yes
No
REPAIR short to power.
For coil-on-plug vehicles:
KEY OFF. GO to A17 .
All others:
KEY OFF. GO to A6 .
A6 CHECK PIP IN THE PCM
Note: The scan tool must be connected to a reliable power source that is powered with the key in the START position (such as directly to the vehicle battery). Also verify that the vehicle battery is fully charged.
Is the PIP PID switching on and off?
Yes
No
KEY OFF.
For 2L engines : GO to JD1 .
For all others : GO to JB1 .
If OK: Natural Gas Vehicles : GO to A9 .
If returning from another pinpoint test or all others:
GO to A7 .
KEY OFF. GO to JD1 .
A7 CHECK FUEL PRESSURE
WARNING: BEFORE SERVICING OR REPLACING ANY COMPONENTS IN THE FUEL SYSTEM, REDUCE THE POSSIBILITY OF INJURY OR FIRE BY FOLLOWING DIRECTIONS IN PINPOINT TEST HC WARNING, CAUTION, AND HANDLING.
Is fuel pressure at the specified pressure (use the fuel pressure chart in Pinpoint Test HC)?
Yes
No
GO to A8 .
KEY OFF. GO to HC1 .
A8 CHECK FUEL PRESSURE LEAKDOWN
Does fuel pressure remain within 34 kPa (5 psi)?
Yes
No
KEY OFF. GO to A9 .
KEY OFF. GO to HC1 .
A9 CHECK FUEL INJECTORS FOR VPWR
Note: Check at least two fuel injectors, one on each bank. A no start condition can exist only if greater than 50% of the fuel injectors are without VPWR.
Is voltage greater than 10.5 volts?
Yes
No
Natural Gas Vehicles:
GO to A15 .
KEY OFF. GO to A10 .
REPAIR VPWR circuit.
A10 CHECK FUEL INJECTORS ABILITY TO DELIVER FUEL
Is there a pressure drop greater than 34 kPa (5 psi) while cranking the engine?
Yes
No
The electronic engine control system is not the cause of the no start. RETURN to Section 3 , Symptom Chart for further diagnosis.
REPLACE PCM (refer to Section 2, Flash Electrically Erasable Programmable Read Only Memory (EEPROM) ).
A15 CHECK FUEL PRESSURE ON NATURAL GAS VEHICLES
Is fuel pressure between 552 and 827 kPa (80 and 120 psi) on the Scan Tool and fuel pressure gauge?
Yes
No
KEY OFF. GO to A16 .
KEY OFF. GO to Fuel Systems, GO to HB1 .
A16 CHECK INJECTOR SIGNAL FROM NGV MODULE
Note: This test requires a standard 12 volt test lamp. A properly operating system will show a dim glow.
Does test lamp have a dim glow while cranking?
Yes
No
REPLACE PCM (refer to Section 2, Flash Electrically Erasable Programmable Read Only Memory (EEPROM) ). GO to A6 .
No light or continuously bright light.GO to HA47 .
A17 CHECK PCM DRIVER TO COILS
Does lamp blink consistently and brightly (one blink per engine revolution)?
Yes
No
KEY OFF. GO to A7 .
KEY OFF. GO to JD1 .

On the engine there is a tube that supplies fuel to the fuel injectors, on that tube there is a valve, like a metal tire valve, this is the fuel pressure test port, you will need a special guage to check the pressure that screws onto that valve, Kragen and other parts stores sell this test kit, it is very inexpensive, about $20.00, but cheaper than having a shop do it for you, if you do the test and you have no pressure while cranking the engine then your fuel pump is bad, the pump is in the gas tank, a big job and dangerous due to chance of fire if you are not cautious.
SOURCE: 93 ford tempo v-6 replaced fuel pump but will not start did reset
by chance the replacement pump you used was it a "CARTER" brand I had one of those quit the same day installed it! also be sure that the feed wire on pump in tank is connected properly! you can change them by taking out the back seat of car!! the seat has 2 clips good luck
SOURCE: Loss Of Power & Unable to Crank Beyond 2-3 Seconds...
You have an issue with your throttle actuator, try cleaning in the area with carb cleaner but more than likely the actuator will have to be replaced

Hello, well at least you know the end cause is there is no fuel at the check valve. Can't really explain cold start part, except the Brain needs a signal from the Water temperature sensor to put it in a "Cold cycle" start with higher idle and richer fuel mix. This sensor is not the one that runs the dash indicator. It also would not kill all the fuel pressure. Most likely a separate problem which can be fixed with a new sensor.
When you mentioned fuel solenoid, were you referring to the Relay in the Black box full of Relays?
A relay would explain the hit or miss fuel pump action. Check the Relay plug sockets for Corrosion. A bad Ignition switch could also fail to power the Relay. Having to turn the Ignition switch 4 to 6 times to get the fuel pump to work can mean the Run terminal inside the Ignition switch is worn. The Start terminal in the Ignition switch would power the fuel pump only while the Starter is cranking.
As for parking downhill, a bad fuel pressure Modulator would allow all the fuel to siphon back to the tank overnight, leaving you with a dry start in the morning. With a working fuel pump this pressure is restored in seconds, but with your problems it can explain why you benefit from downhill Parking.
You are correct about strange actions. Seems you have 4 or 5 things that could be wrong with nothing being definite. The Ignition switch is cheap to try, no expense to look for corrosion in the Relay plugin. A Relay for the fuel pump if it is not the Solenoid you were indicating. If no pressure again at pressure check valve, disconnect tank side of pressure Modulator and see if it has pressure (Indicating a faulty modulator). The Temp sensor for the Cold start cycle.
Would like an update for what you found.
