Infographic: Guide to Diagnosing Common Starting Problems

It can be incredibly frustrating when your vehicle won’t start.

It can be even more frustrating trying to figure out why.

Morris Rosenthal created a diagnostic flow chart to help people troubleshoot the possibilities. We found it, liked it, tweaked it, and are now sharing this infographic with you. Your very own swear-word-reducing, stress-relieving roadmap to getting that engine humming again.

It’s the gift that keeps on giving the whole year. (That it is, Edward!)

    On your Starting diagnostic chart, believe you missed, started runs, grinding sounds. Could be the drive clutch, have starter checked

  2. Just because a battery reads 12 volts on a volt meter doesn’t mean it’s a good battery. Leave the volt meter on it and try to crank it. If it drops below 9.5 volts when you try to start the car then it’s a bad battery. Another thing you can do is hook a load tester or a conductance tester up to it and test it.

    Engines Dan turn over but if you have timing belt issuers then camshaft may not be turning. Research Interference vs. non-interference engines.

    Paul.Your problem is the Duraspark ignition module is starting to fail or it is an aftermarket replacement of lesser quality.This is a fairly common occurance on these Ford first gen electronic ignition systems.Dan.
