I replaced my starter and the car sometimes is hard to start now. Once started, runs quite and still gets 30 mpg. Every sensor is plugged in and hoses are reconnected. Anyone have this problem

 

Check the batter and terminals.

 

check your grounds also the ground under the hood where fuse box is....make sure free of corossion and the grounds to the fuel injectors..

 

Number one question that should have been asked...Any Codes/Check Engine Light?

 

Yes, it has a maf and a knock sensor code

 

make sure you plugged the maf back in, also check the start signal fuse under the dash, sometimes they can look good and still be bad I believe that its a 7.5 amp fuse.

 

I used connector gel and cleaned the battery terminals. Got better but sometimes hard start. Random when its hard to start. Most of the time it starts up instantly

 

I cleaned the main ground and the ground on the drivers side fender. Changed some fuses but still sometimes hard to start

 

have you checked to see if your ignition switch has play in it

Seems to have no play.
Codes
P0325 knock sensor
P0150 air fuel sensor
P0100 maf sensor
P0105 maf sensor

 

did you have this problem before you changed the starter?

 

It's crazy I'm getting this problem here and there too, most of the time starts right up, and once Ina blue hard to start, when I turn the key it just does like a jut jut and doesn't turn on, then I'll go and remote start it.. And it never fails to turn on...what's up??.

 

your ignition switch if u can remote start no problems then its ur switch

 

P0100/P0105 MAF Sensor is your problem. DId you reconnect it and also did you damage harness or sensor in any way??

 

It could be the starter. I know people had this kind of problem with the aftermarket starters and when they put the nissan starter in problem went away.

 

not the starter if it starts every time no fail from the remote start there is a issue from ignition

 

Added a ground from the starter to the battery, fixed the problem

 

I was just going to suggest that.
