1989 Mercury Tracer station wagon. 1.6L fuel injected engine with A/T. Has 188K miles.The car has an intermittent starting problem. Some days starts immediately, next day just cranks and cranks and won't start. When it starts, it runs good. I have replaced the battery, distributor (incl cap & button), ignition module, and ignition coil all in the past 45 days thinking the intermittent starting problem might be electrical. It might be a fuel problem, but fuel pump is inside gas tank -- too technical for me. This is a great value for someone who can diagnose the intermittent starting problem and fix it. the years only went back to 1990. even thought its an old make I just really need sum insight on this problem. thank you

Check the compression, it needs to be at least 150 psi on all 4 cylinders, or the engine is too worn out to run reliably. That is where I would begin.
The engine stalls and then , immediately, the engine can be started again. Shop has had engine on computer and has nor been able to diagnose problem. What could be cause?
