Hi there I'm gonna start with the parts that are new EGR VALVE, ALTERNATOR, CRANK SHAFT POSITION CENSOR, CAM SHAFT POSITION CENSOR, DPFE, COIL PACK, PLUGS, WIRES, THERE ARE NO CODES ok here I go Last year I was driving in GA it was about 100 degrees out I was running the ac my van just quit running, I turned the key, just turned over, waited 5 mins fired up and on my way for about 1 mile till it did it again and again and again. I finally made it to a dealer I had a ford so called mechanic sitting in the passenger seat with his laptop plugged into my van and him tell me I have know idea why your van is shutting down everything looks good and normal on the computer. I never figured out the problem it rained for the next cpl days which kept it cooler, I got back home up north in NY and it drove great for about 8 months, till I came to TX. 100 degrees every day and the problem is back. I drove the van with the hood propped open about 8" to force air into the engine compartment and it worked for a while but on those extreme high heat days like 106 it didn't matter it still stalled. The van finally died had it towed to ford they said the fuel pump was bad. So had it and the filter replaced van ran great for 7000 miles not a problem at all. Now I have the problem again and they say the fuel pump is good I tested it myself, cycle the key the pump reads 35lbs, running reads 32lbs, watched guage as van quit gauge spiked to 40lbs then went back to 32lbs please help me if you can thank you, Mike

If it's 10 - 80 deg rain or shine I have no problem only happens on very hot or extreme hot days

Vapor lock? Relay getting hot? HELP!

Hi miket6767,

Thank you for the donation.

I can think of 3 items that have a remote possibility.
1. Intake Air Temperature sensor.
2. Engine Coolant Temperature sensor.
3. Ignition switch.

Additional data that I hope are helpful.


On models with electric Secondary Air Injection (AIR) system, perform the following procedure after the no-start condition has been repaired:
Disconnect AIR solid state relay.
Start and run engine until surplus fuel is used, and then reconnect relay.
Disconnecting AIR solid state relay may set a Diagnostic Trouble Code (DTC).
After repairs are completed, clear DTCs.
Preliminary Checks
Check Inertia Fuel Shutoff (IFS) switch.
Check fuel pressure and quality (octane, winter/summer grade fuel, methanol, etc.).
Check add-on alarm/anti -theft devices.
Check wiring harness connectors.
Check for disconnected or restricted air intake duct.
Check fuses and relays.
Symptom Checks
Check the following items:
Check ignition and fuel system.
Check if engine will start and run at part throttle. If engine starts and runs, Idle Air Control (IAC) system may be defective.
Check for restricted exhaust system.
Check engine mechanical condition.
Check compression, camshaft, valve train components, etc.

CAUTION: Extended cranking, due to a no-start condition, can load exhaust system with raw fuel, which can ruin catalytic converter after engine is started.
