like the title says, it cranks but wont start 100% of the time. Sometimes it will start like nothing, other times itll take forever to start. Sometimes its start and run at around 100 rpms so i have to rev it high to keep it on. Once its on it runs fine accept sometimes the rpms drop extremely low on take off from first (almost stalls). Other times when i start it, it will idle at an ok amount of rpms, but itll spike and be full of hiccups. Once driving, everything is fine. Now im pretty sure its the fuel pump. The thing is I just had it replaced a few months ago. Now is this a faulty fuel pump or another problem?

running a ka24de btw.
