i cant find anything different than what ive already tried. my rig has stopped starting on its own. take spray in the intake to do it. i replaced the fuel pump, now have a around 40psi while running, and no its back to not starting. if i spray stuff into the intake it starts. when it starts on the spray, it idles high till i unplug one of the tps pigtails and it calms down. and by high i mean around 2k. when it used to start on its own, it would run perfect. start right. and not have a problem. with it now, when its finally running and going through the tps steps and it calms down, it runs fantastic. no hesitation. no rough idle. but i shut it off and then it doesnt start again till i spray stuff in the intake.
so here goes:
full tune up
new tps
new cps
new fuel pump
have fuel pressure
have spark
im lost. it seems initial fuel is the issue, but i dont see how its not getting fuel if theres good pressure.
lastly, i noticed the little white thing that has to do with the fuel system(has two wires that connect to it and is bolted to the inside of the driver fender on renix vehicles) it gets really hot. it even got pretty warm while just trying to crank it a couple times a few minutes ago. what does that do again and how to tell if it works?
