Item problem

Estimated I tell you that I have an S10 of the year 98 and I have many problems in the game. I change the idle censor, the battery, the spark plugs. It has a good start but the engine does not turn on, and after it turns on for some reason it does not fail more in the subsequent games it is only in the initial departure of the morning.
I hope they help me with this problem since neither the scan nor the mechanics have been able to find the fault.

The X motifs that do not start can be several but if I already corroborate admission and ignition systems, I would have to measure the compression. If you have low compression, you will surely cost it in cold, and with the hot engine it starts well. The low compression can be x problems in the cylinder/piston/rings set, cover of the cylinder or poor valve regulation.
