Toyota Duet 1998

Hello Friends of MDM, I need help with a Toyota Duet 1998 Twin Cam of 3 cylinders. The problem is that it does not start even though it already checks the voltage of the batteries, ok, the spark is fine, the fuel pressure, OK. But a day before I mean yesterday the engine stayed without refrigerant liquid, he warmed a lot. Then I start perfectly. But today he does not. I await answers.

The first one to do is check the compression of the cylinders because if the cylinder head is bent then it will not start, test and warn.

We already verify the compression of the butt and that is the preoclema. Thanks for help. We will be in contact.

Okis.
