A friend of mine has a problem some mornings starting his Rav 4. The head gasket has been done lately as she was letting compression into water. Since head was done this starting problem has surfaced.

Most of the time it is ok but maybe 1 out of 5 morning it takes a lot of cranking before it fires off.He has had injectors checked and compression is ok. Water problem is ok now.

Any ideas

No fault codes coming up
