No fuel from the throttle body but fuel system is fine. Intermittently the engine has cut out. I have been able to start it before after a few tries and would run just fine. Has cut out while driving. This time it absolutely will not start. Just replaced distributor cap and the plugs are in the proper firing order. The spark plugs look good. Runs great when it decides it wants to. Through process of elimination and some research.I'm thinking either the ignition coil or the ignition control module. Any ideas or suggestions?

If it won't start, it is either a fuel issue or ignition issue. Check to make sure you have good spark to the plugs (a good hot blue snapping spark). Also, check to see if the fuel pump is producing the proper pressure to run the engine.

I reread the post. If you have good fuel pressure but nothing is coming from the injector, check to make sure there is power to the injector.

I don't know why, but this just showed up in my mail. Sorry it has been so long. Have you had any luck with the issue?
