H3 WOILL CRANK BUT NOT START

Hey everyone. New on board have read many post and got much help. But first time posting. Sometimes my h3 06 will start to crank rum rough for a second then die. Then it will not start for like 10th min. I read other posts and most people had remote start. I don't have it. This happens every once and a while but it s. Any body have any ideasucks when it does.

Sounds like it could be fuel related. Better take it in for diagnostic testing to be certain.

Re: H3 WOILL CRANK BUT NOT START

you may want to check the fuel pump relay in the fuse box. This happened to me the other day when I went to leave from work. Luckily the headlight relay is a match so I switched them out and it cranked right up. Strange think is that the headlights still worked. Im thinking the relay wasnt totally bad yet but on its way out and wasnt giving enough power but it worked well enough to allow the headlamps to work. I probably shouldve had it tested but I just bought a new one and threw the old one out.
