yj non starting issue

i am working on my moms 90 wrangler with the 2.5. she has been having some starting issues and would die ocationally. now it is to the point it wont start at all. the starter will turn over and once or twice it kicks but nothing.. had her turn it over and im not seeing spark.. holding plug wire from plug but dont see anything did the same thing with the coil wire..no spark..unless i am doing something wrong... just did a complete tune up on it..cap wires plugs then coil and today the crankshaft position sensor... hoping that was it since it had bare wire out of the plug on the top. put starting fluid in it still nothing... any ideas?

Just to clarify you took the plug out grounded the threads on the engine cranked it and don't see a spark?

It also may be faint if there's a lot of light.

The coil should be seeing 12V on the connector with the ignition power "on". Is that the case?

Its the clip with two wires (red and green?) that plugs onto the coil. You pulled it off to replace it.

Yea all you need to do on the plugs is take one out. Put the plug wire back on it. Touch the threads or the prong on the end to metal on the engine somewhere. Crank it over and check for spark. You can do it

It means milivolts (1/1000 of a volt)

Or if you prefer your not getting 12Volts to the coil. And there is your problem.

To clarify you checked the voltage with the meter on 12VDC and with the ignition switch in the "ON" position? Right before the "start"

Also check with your meter on the next larger scale. Whatever that my be, 20, 50, 100 VDC. Make sure it is DC. (straight lines for a symbol, not wavy)

OK I gotcha now. No you need to set it to the red "DCV" setting. (From "OFF" to the right one cllick)The 12V you have it set to is for checking a 12V battery.

Also you need to connect it to the clip like you were doing. That is where the power is being supplied from.

You should see somewhere around 13V on you meter.

Good to hear it's going. But without the problem found it may leave you stranded.

Just for future reference and your safety. Don't set it to mA or A and try to measure the current/amperage. You will kill you meter and make a large spark if used incorrectly.

Research how to do this before doing it.
