Narrative:

Departing mex at xa:30 first officer spooled engines for takeoff. #1 was warmed, #2 failed to spool but remained frozen at idle power. We returned to the gate and had maintenance check out the problem. The mechanic found and drained water in the fuel control unit. We were cleared to do a runup at the gate, with the engine now running properly. This took about 24 minutes and we pushed and departed with no further problems. En route I realized we did no paperwork on this and upon arrival at iah I asked maintenance what they wanted in the logbook, since it should be addressed. I was told to put in 'information' write-up. So I wrote something to the effect that the #2 engine failed to spool, return to gate, and maintenance did a quick repair to have us on our way. I thought about writing what specifics the mechanic told me, but did not want to put down something that was not totally accurate or complete, so left it like it was. I was later contacted by the company about the occurrence and determined that this episode was not a proper way to handle the situation. Lessons learned: always put it in the logbook and let maintenance do their own corrective action sign offs. Contributing factors. This particular pairing is very difficult to get proper/adequate rest because of the nature of how it is put together. The wakeup is tough enough, but trying to sleep at will beforehand is even worse. Anyway I felt like my judgement and alertness was compromised by the 3-4 hours of less than restful sleep. I'll work harder at making sure something like this improper practice is avoided. Callback conversation with reporter revealed the following: conversation mostly concerned the quality of his layover in mex. Reporter actually had about 2 hours sleep prior to the incident and he feels that this contributed to his possible complacent approach to the required logbook write-up. Callback conversation with reporter revealed the following: 151813. First officer had only 2 hours sleep prior to incident. This caused by being locked out of his room and unable to converse in spanish with hotel personnel.
