I'm going to assume it is a 99-03 7.3 truck. Did he turn it off or did it shut off on its own?does the tach move when trying to crank?? if not, go to Ford dealer for a free CPS replacement to start.
Depends on the year. Only the OBS does this.
if still won't start, watch to see if the "wait to start" light comes on. if not, you have a blow fuse.
more info...1994-95 7.3L. truck shutoff on its own. tachometer moves when cranked. acts like it wants to start. fuel not getting to all injectors.my brother-in-law's 7.3L diesel shut off and now it won't restart. think it might be something in the fuel system. maybe injectors? maybe relays? fuel flow not there. any suggestions?
Then why would you plug AE into your OBDII port if it is not OBDII compliant? I have never understood this. OBD II is newer than OBDI so why would a 94 be OBDII and the 99-03 not?The tach movement isn't valid after 2000, since this is a 94 my bet would be CPS, they are only $28 and you should have a spare anyway, I would change it and see if she starts, if not you have your spare. You really need to have it read for codes if this doesn't fix it. Not sure if a 94 is OBDII compliant. I know the 99-03's aren't. You really should try and post this in the OBS section you will get a better response.
$28.00, or $128.00? I paid $132.xx for mine, but I got it from a dealer... Overpriced... Well maybe, but it still works, 4yrs later. I'm sure they're less now regardless where they come from.
You are 100% correct... except I question the GVRW part. In my snap-on OBDII books, they state that anything over 14000 would not be OBDII. The same "generic ODB II" cartridge works on my diesel or my Jeep.It's not the port that's OBDII, it is simply a connection, it is the computer language the two use to communicate with each other. You have been around diesel forums a long time, you know the fact that the generic scan tools from AZ, Advance etc.... don't work with our trucks without the specific software bundle for our trucks, this is because once a vehicle goes above a sepecific GVWR they don't have to be OBDII compliant, they can use their own codes and communication system in those vehicles. Our trucks fall into this catagory. How many times have you read posts where somebody argues they have no stored codes because the dude a pep boys checked it and said so, only to find out later that when a proper scan tool was used the codes were retrieved and pointed to the problem? When you buy the AE software, you must buy the one compatible with our trucks. I hope this helps.
:thumb:Thanks, it was the CPS unit in his truck.94? I say CPS. Mine was bad and my tach still moved.
