NOTE: i posted this in tbi as well for im not sure exactly what the problem is , so sorry if you are reading this twice


ok , drove my car all day, power was feeling sluggish, ...got home, turned the car off, ....waited about two mins, and was going to put the car on ramps, cranked it back up, ...wouldnt crank.....so i pop the hood, take off the air cleaner, and try to crank it again...no fuel comming out the injectors....then after about 5 revolutions of the engine it started up but reved REAL slow, ran like crap....i nail the gas, the fuel wasnt spraying out, its was more like rain drop sized of fuel pouring out, then let off the gas and it would be an even mist. slam the gas again, ...half spraying half dripping. turn the car off, ...pop the gas cap off, huge hiss...so the pressure is obviously building.....i think....

this has happened before but it ONLY happens in 2 hour stop and go traffic in the summer. so it has to do with something heating up and failing to function correctly --at least thats my theory--

could it be the injectors heating up and failing?

fuel pump dying?

all the fuel lines are ran away from high heat sources.
whole ignition system is new, plugs and wires are good.
this is a fuel delivery related issue.

so is it the fuel pump or injectors?
anything else that could cause this?

 

Sounds familiar. I'd be checking the fuel pressure. You may have a filter or pump issue.

 

swapped the filter after the problem, and it brought back alo t of hp i had lost and didnt know how, ...its amazing. still not sure if the filter itself caused those injectors to spray like a sprinkler / rain drops. im saying injectors. only because they sprayed so horribly.

correct me if im wrong though, could the pump be giving less pressure and causing it to spray unevenly and in huge drops?
