Car can't start but cranks. Newbie
 

Hello, everyone sorry for making a straight question. I am new to this forum..
I've a problem, yesterday somehow with no reason my car stopped working, I mean it wont start but its cranks. So, ive checked and channged all the spark plugs and it has a spark. Its 99 mx5 1.6. So ive checked fuse under the bonnet. the 15amp one, seems its fine too. ive put some petrol in the throttle body, engine worked but not for long, and started weird. Ive tryed to let my bud to crank the engine while I was trying to hear if anything happens in the fuel tank, nothing. So I thought maybe its a fuel pump? but wait it could be the fuel relay? Or even the Main relay would it be? Any suggestion lads, really need that miata running on the weekend. :(
Thank you in advance.

Edit: Also I am newbie in cars, so where can i locate fuel relay? Its JAP.

Check the simple stuff first. Battery charged? Gas in the tank?

Oh yeah it is charged 12V a lot of fuel. I did checked this ofc..

Either the fuel pump has stopped working because it failed or the electrical circuit to it has stopped providing power. The electrical circuit could stop providing power due to a fuse or relay being bad or perhaps the sensor that tells the ECU that the engine is spinning is not working correctly. Any of these could cause a lack of fuel.

Sorted lads, fuel pump. Used Lada, toyota, chrystel new fuel pump that what factory gave me, did abit re wiring and ualia starts perfectly and drives like new, thank you. :)
