Sometimes it works, sometimes not. Could be a pump problem. Have you checked fuel pressure? Where is your lift pump located? In the tank or on the frame rail?

its on the side of the bolck. i dont know wat my fule pressure is i dont have a guage or the tool to test it.

well i just checked the apps with a volt meter and it was reading 2.42 and the whit sticker on the back says it should b at .568 could that b the issue?

your truck could be starting in 2nd too you could have a valve body issue or your tv cable is too tight. try pulling it into 1st and see what happens.

i finaly got my truck to throw sum codes for me doin the key on-off-on-off-on and i got a 1693 pcm, 1698 ecm, and a 0122, i found sume codes on line and the 0122 is the apps volt is to low. i set it from 2.5 down to .586 like the sticker on the back said. could i need a new apps? and i also found out that the 1693 said generic fault in the bus or pcm/ecm interface. idk wat the pcm or ecm r. any ideas on where i should go from there? i couldnt find 1698 code

is there anyway to build more boost on a 1999 24 valve

Did you do it with the key on or off? It needs to be set with the key on. That 2.5 sounds like the reading I showed with my key off is the reason I ask, so if you did that you could have set it too low.

i did it with the key on.
