Thanks for your question. Sorry you're having car problems. If I go off line, just leave a message and I'll be right back. DO NOT leave feedback yet. When it doesn't start, what is it missing, spark or fuel? Thanks, Ron
has fuel not sure about spark
OK, we need to check for spark at the plug when cranking the engine. If your coil is on top of the plug, you'll need to put a plug wire on the coil to check it that way. Thanks, Ron
yes it has spark
OK, do you know what the actual fuel pressure is at with a gage attached? Ron
yes 60 lbs.
OK, is the security light on or flashing?
OK, then check for injector pulse at the injectors with a NOID light.
Fuel may not be getting to the injectors
has injector pulse
Great, then check compression next it would have to be out of time if ALL the other items mentioned are good. Please don't forget to rate me as high as you see fit and I can still assist you afterwards if you need me too. Thanks, Ron
