i plug mine in to a light post that is switched inside the house

30 minutes plugged in makes a big difference on startup when 20 f out for me, you might need 45 minutes or more

Thumbs up

These have I think a 1000W heater stock. I found that two or three hours plugged in will get my oil temp to around 100F when it is about 30F outside...so warm I can crank and start without glow plug relay hooked up. My 300SD has a 400W or so, takes about four hours to make a good difference.

Anyway, I would try it and see if that helps your truck start. -9F is pretty chilly and I doubt my truck could start in that as the engine is so beat, I have only tried it to low 20s and it started then. Knotty has a great thread for cleaning your battery posts of invisible corrosion, checking for resistance, cleaning grounds to block, etc Helped me diagnose my flooded F150 for slow crank.

This thread needs a link to the online diagnostic manual but it seems to have changed. Another thread needs a link too, for the diagnostic port. I looked at diesel stop, that's right isn't it? Did it change or is it me?

I'm thinking about replacing the cam position sensor. Is there a diagnostic procedure to identify a bad cam position sensor?

It starts working when you replace it? lol just kidding

If you have a bad cps, you would see no movement on the tach while cranking.

I've been out of pocket - Broken leg. I'll be back in business in a couple of weeks so will need to get back to the truck. I thought the '94 1/2 did not have an electric fuel pump, but was looking at the fuse block and noticed that there is a fuel pump relay. Should this be an in tank or in line pump.

Is there a Bluetooth ODB scanner that will work on an ODB and an ODB2 vehicle. I have a cable adapter that will allow an ODB2 to plug into an ODB connector.

Thanks, Doyle

94.5 7.3l does not have e-fuel unless someone has removed mechanical and put in e-fuel as I did. No pump in tank.

Scanner

The ad seems to say that the vehicle needs to be OBD2 compliment. I think I will get one if only for my other vehicles. However, will I get useful data from my ODB (1) ‘94 1/2 using my ODB to ODB2 adapter cable?

You have a obd2 connector under the glove box. If your computer has been re flashed it will work. . I use AE

I use that VGATE adapter in my 95 F350 and works in my 2009 Tacoma and have used in a 2015 Pilot and a bunch of others.
