Whatis lost when it won't start? Fuel or spark? This is the first questionyou must answer before you start troubleshooting the problem.Tobe honest, when I see a problem like this on a car with an aftermarketalarm system, I tell the customer to take it to the people whoinstalled the alarm. About 75% of the time it is the fault of theaftermarket alarm. I'm not trying to get out of the work, it just savesthe customer from spending lots of dollars to diagnose the problem andusually wind up telling them it is the fault of the aftermarket alarm.
Whenthis happens we have to determine what is lost when it won't start,fuel or spark. The next time it happens, take a hose off the intakemanifold and shoot some carburetor cleaner inside it. Try to start itand if it starts right up, you have a fuel problem. If it doesn't, takeoff a plug wire and stick an old spark plug on it. Lay it on somethingmetal so you have a ground and crank it. There should be a nice, brightblue spark. If not, you have an ignition problem.
