cruiser54 Posted May 28, 2015 Share Posted May 28, 2015 Will check that out Friday when I get back to the tRuck.... Best way to observe that is with a timing light flashing on the spray pattern. Link to comment Share on other sites More sharing options...
88whitemanche Posted May 28, 2015 Author Share Posted May 28, 2015 Any other way? I don't have one or anyone that does.... Also after replacing the pump... I noticed after idling (30 mins), and restarting it the idle would shoot down to 50-200 rpms and it will stay there for about 30 seconds then start hunting for an idle to bump it back up to 500-700 rpms... Could this be tps? Link to comment Share on other sites More sharing options...

88whitemanche Posted September 29, 2015 Author Share Posted September 29, 2015 Ok I haven't driven the truck long distance up until today and it shut off on me 3 times today so I went ahead and readjusted the tps which was out of sync... I got it exactly at the 17%....we'll see my test run on my way to work tomorrow and see if it helped with the shutting off issue.... First tps readings were 4.84 and 1.41.... So adjusted to 17% of 4.84 percent is .82 which where it is currently.... Link to comment Share on other sites More sharing options...

cruiser54 Posted September 30, 2015 Share Posted September 30, 2015 Try this first. With it running, wiggle the key a bit and see if it shuts off. Link to comment Share on other sites More sharing options...
88whitemanche Posted September 30, 2015 Author Share Posted September 30, 2015 Started the truck up and played with the keys, wiggled the keys, moved the steering while moving the keys, replicate the movement of the keys while on a drive and it didn't shut off...I've been doing the past 15mins... It doesn't shut off while sitting idle in the driveway...by far only in motion Link to comment Share on other sites More sharing options...
