Hard start(motor dragging) then sometime nothing we get dash H

have vehicle scanned for trouble code[s]

Sounds like a weak fuel pump

Hi Thomas, sounds as if the starter motor is 'dragging' Basically that means either the bushes or brushes are worn or something else in the starter motor is causing the drag. I think the problem is in the unit giving the problem. Regards Johngee

Possible HVAC blend door motor skipping over the gear drive due to a jammed blend door. Also it could be valve train noise in the engine, I would need to hear it really.

sounds like a worn out starter.
best to bench test it for it sounds like the armature has swollen through time and rubs against the fields in the starters motor casing

Sounds like stuck starter moter solenoid. Get a mate to tap the solenoid (smaller cylinder attached to the starter motor side) with a hammer, quite hard, while you repeatedly turn the start key on & off. If no joy (and this is needed anyway) have starter removed and reconditioned.

The blower motor resister shorted out common problem. It is located behind the glove box on the HVAC assembly.

I can think of 2 possibles,it could be a bad battery cable or an intermitent short in the starter solenoid, check or have the battery cables and there connections on both ends first not only are they a cheaper fix but the problem you describe sounds like a current flow issue.Test them with or have them tested with an ohmmeter they should show o ohms resistance,and while not attributed to the problem I do not reccomend using Bosch spark plugs of any variety,the best plugs for any Japanese vehicle are NGK's,this comes from my personal experience with them and other techs that I have worked with.

Could be a bad starter motor or a bad starter switch.

Check all your connections, make sure they are all clean & tight. Do you have a multimeter available for a voltage check at battery, before & after starting?
