Sudden engine stop on freeway....

haywoodphotomaccom · 02-13-2013, 10:31 PM

Last week while driving on the freeway the van lost power and stopped by the time I got to the side of the road. Turned the key off and back on and it started back up and has driven fine for the last week until today. The first time I thought it might be an isolated event and did not bother to have it checked out.

Same thing happened this morning but fortunately it made it through the rest of the day of work. Going to have it checked out tomorrow. Any ideas on the cause?

Fuel pump relay would be my first guess.

Were you using cruise control?

Do you have a ScanGauge or anyhting else that can check for codes?

I do have the Mike's Tuner gauge which I believe has similar ScanGauge capabilities. I'll pull that out this am.

Fuel pump or something related was my first thought.

Not on Cruise Control.

Been so busy I have not had a chance to check anything which I will pay the price for. Need to get on it today.

Thanks for all the suggestions and info!

If there are no stored codes, that pretty much means its losing PCM power or has a bad PCM ground.

Any other fault, including the fuel pump, will trigger some sort of code (even if that code isn't apparently relevant.... Fuel pump fault will trigger O2-sensor-lean codes for example). At least that has been my experience.

Do you have some sort of aftermarket anti-theft system? Any tampering with ignition wiring increases the potential for power interruptions to the PCM.

We have rewired most of this van now and installed a new stereo. The stereo installation people did not do a great job which has been a concern.

Might be between all of our wiring changes. Hope to check out the codes today.

I will report back any findings...

Our new Ford van had at least 2 wiring problems from the factory, one which required towing. We've also had a fuel pump strand us in a Ford van. I hate it when it's intermittant... It's better if it just dies.

I had that happen and the Ford shop in Idaho said it was the mass air flow sensor. Hopefully they didn't feed me full of....
After they cleaned it I never had an issue since.

Prior to the trip I had the shop do a full tune up and the air cleaner was replace but I saw the mechanic blast air inside the housing.

I have suggested this once before but I think we need to add another category on the home
page for 911 breakdowns on the side of the road. The Cummins group has this and its great
for when you traveling and experience mechanical trouble, I,v seen other members(Cummins group TDR) offering to help and even putting up said stranded members at their home or even driving out to help.
