My wife’s 07 accent will not start. I have put new fuel pump, 2 of them.for fuel Then put new catalytic converter on for air (new air filter also). Then put coils plugs and crank shaft position sensor for fire. It started ran fine . Let my wife’s son borrow it for work the next day and had to have it towed. Tries to start every now and then . But to avail! I am stumped. If anyone has any advice I would be greatly appreciated.
also put and purge valve. And the fuel pump is running.

 

Hi Brian,
Since you were able to repair the problem initially, I would suggest you recheck your work. Maybe a wire came off .
Some Crank sensors come with a gasket, was one removed and one installed? Sometimes , two get installed and problems show up.

 

Yes I check the old part it still had the o ring . Then pulled new part took o ring off put back in just to check the clearance on the o ring and it still hasn’t hit a lick. Put o ring back and am moving forward. If it gets hot outside it will try and start. Once it gets cold will not fire at all.

 

Whatever we are looking for appears to be affected by temperature,,,,,,,,,,,,,so,,,,,,,,,,,,,,,,,,,,,,,, ,,if you are sure the vehicle will start at the right temp., one at a time pour some cold water over some of the areas you worked on. The sudden drop in temp might just reveal the faulty area or component. . Just do one at a time and try starting the engine because if you cool down everything , you will be back to guessing.

 

I had the same thing happened to my car and a mechanic said it was the timing belt
