Hi, I’m Ron and I’ll be helping you today.

Before we get started though, please understand that I don't know your skill level or tools you have to assist us. Also understand that I can't see,smell, hear, or touch the vehicle either, so patience is appreciated.

My goal is to make you happy and get a great rating in return for my time.Sometimes I have to give you bad news that I know you didn’t want to hear, so please don’t shoot the messenger. This is a great site, but it doesn’t replace a shop or necessary tools.

Check fuel injector pulsing with a noid light. If the security system is not the problem nor the pump or crank sensor, then the computer may be at fault. this can all be tested with a scan tool.

Thanks, Ron
