If my second gen starts on usually the second time I try to start it, and occasionally, nowdays it doesn't start well. What is the problem? are the fuel cells blocked? should I take out the fuel pump fuse and let the fuel burn? If anyone knows what might be wrong please tell me Thanx -Tony-

 

Fuel cells? That's a nice mod, man...Where do you get the hydrogen from?

You need to do a compression test, to see how your engine's doing. Low compression, among a host of other possibilities, causes hard starting...

 

did u check for constant spark on all coils
check the output of your fuel pump (volume and pressure)
check that no one kinked your fuel lines (eg: hoist lift etc)
plugged fuel filter,
bad plugs, and if u still have your original intake check that your filter is good and nothing is blocking your air passage!

good luck

 

sounds like a hot start problem

 

Make sure your THERMOSENSOR is operating properly- ie plugged in all the way., If it's an s4 buy a code reader from me and then run codes..LOL
