I've been a member of the formum for a while but never posted, this is my first. My truck, I've had for about 2 years now, is a 1998 1500 SLT laramie short bed with a 5.9 L and automatic, 180k on it. 5 days ago it died while driving just lost all power I coasted to the side and got a tow home, I replaced the fuel pump having had the same thing happen to me before in other trucks, and that being the problem. It took a lot of cranking to get it going but it did start I turned it off and it started up again I drove 18 miles on my way to work in about four miles before I got to work it dies the same situation but this time I can hear the fuel pump pumping and I've got pressure at to the rails. I've always got the check engine light on because of a another problem but I did not scan it the first time it died, but this time I plugged in my scanner(Autel AL519) and came up with five codes. I replaced everything that's was possibly bad and three codes erased the two codes that stayed are the P0505 IAC system and P0122 TPS (switch A circuit low) so I replaced them again and it still says they're bad. So now I'm figuring it's in the circuitry which is what my scanner said was the other choice or could it be the PCM. Could there be another sensor causing something and not showing up on the scanner? Does every sensor go back and throw a code if they go bad so that I should I be able to find it. I'm desperate here I've lost three days of work and it cost me 2 tows from a tow truck .
