pulling codes, like pulling teeth?
I'm having some problems with my I6 EFI speed density engine. I was going to replace all the sensors in the engine, but the 'ol wallet wont allow for it. I did, however, pick up a code scanner for it. For some reason I can't get the stupid thing to pull the codes though...it says for the 4.9L to depress the clutch and then put the scanner into the test mode. I've had a buddy help me by having him push the clutch in, but when I flip it to the test mode and wait for 5 min, nothing is sent to the scanner. In the book it says that if nothing is sent there is a bigger problem and that needs to be fixed first. Any clue what that problem may be? I'm at a loss at this point.

Have you tried doing it without depressing the clutch? I have run into issues before with the scanner not reading codes if the nuetral drive switch was not reading right. I personally have never depressed the clutch to get the codes, just had it in nuetral. Hope this helps.

Don't take offense, but did you get the OBDII scanner? I just ask because you can't get any codes and said that your wallet won't allow for replacement of all sensors, but an OBDII scanner usually costs more than all the sensors on that engine. If this isn't the case, I'd pull th edash apart and fix whatever the po messed with and then try the scanner.

So where do I get one of those code scanners I have a 1988 F150 and I would like to Check it out, or should I just take it to a Diagnostic shop and pay to have them do a diagnostic on it and tell me whats wrong?
Thanx

Found out my issue with it not pulling codes. I have a guy with a snapon code scanner, even that wouldn't pull codes. Took the ECU out and there are definite hot spots under some of the chips. So it looks like the ECU is in limp mode and will have to be replaced!
