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.

(distributor) he means that. You should check that and also check your wires. also when you try to start it and push on the gas does it turn on?

Distributor. Though I doubt it's that.

Sounds like an air/fuel issue. Based on your Fuel Pump problems. Have you checked the FPR?

I just had my crank angle sensor fail on me in my ka24e. It would idle irradically then barely run. Run fine then stall and not start. Eventually wouldnt start at all. (crank but no start)

sounds exactly like my problem. thanks for the advice.

I found a cracked hose, replaced it, didnt seem to do much at first but now it seems to be starting and running fine. Im certain its not 100% healthy.

im running a ka24e, dont know why i put de. Car seems to start 60% of the time after changing a hose. Problem now is the engine is chuggin, and has major acceleration lag in low gears. lag to point where i almost stall in 1st.
