Hard start.......in need of help
 

So I've posted this before and it is progressively getting worse. So here it is, basically once I leave the car for a few hours it takes alot of cranks to start and sometimes I have to stop just so the starter doesn't burn out. It cranks hard so it's not the starter/battery. Once it starts it runs fine and will start fine if it's within a few hours, anything after it's hard to start again. At first I could leave it for at least 8 hours but now it's shorter so whatever it is is getting worse. It doesn't matter if it's hot or cold. So far I've replaced or checked.........

ignition coil/cap/rotor
plugs and plug wires
fuel filter/FPR/ injectors
main relay looks good

Also not throwing a CEL..............I'm so stumped so any other things anyone can think of ???

I'm having relatively the same problem with my 2004 nissan sentra. I brought it in to get the problem fixed under warranty on tuesday and the mechanic called me back later on and said told me that they have no idea what was causing the problem so they are replacing the whole fuel system (lines and all) from the fuel pump foreward.

You probably didn't want to hear that huh?

you didnt mention ignition module sometimes when they get hot they can cause problems

Re: Hard start.......in need of help
 

it's actually easy to start when it's hot just when the motor has cooled............I just swapped dizzys and we'll see tomorrow morning.

got my car back today. They replaced the fuel pump and decided to test it one more time before starting on the rest of the system. Fuel pump fixed it.
