If the engine still doesn’t seem like it wants to start, probably fuel is getting into the cylinders and your problems lies somewhere else. However, if the engine runs momentarily and dies, then the problem is that fuel is not getting to the cylinders. Check for a clogged fuel filter, or a bad fuel pressure regulator.
What to do if you don’t see a spark in your spark tester?
While watching the spark tester, have an assistant crank the engine. You should see a bright spark jumping the gap in the spark tester. If you don’t see a spark, repeat the test. This time, adjust the spark tester to 30KV. If still you don’t see a spark, repeat the test and set the tester to 10KV.

Even if the check engine light hasn’t come on, you may find a pending code that can guide you in your diagnosis. False input or lack of input from sensors like the crankshaft position sensor (CKP) or camshaft position sensor (CPS) can prevent the engine from starting.

Is there a spark in a GM 3.8L engine?

What should the PSI be on a spark plug?
I got 120 psi with compression test…..can’t find the correct compression, but I put a teaspoon of oil in spark plug hole and it went up to 150 psi….. so I guess that’s a good indication of valves, rings, or something (right?)…. Dirty injectors, plugged fuel filter, timing is off?
Why does my saw have spark, gas, and compression?
I have spark, and after repeated cranking the plug is moist with fuel, so I think I have spark, fuel, and compression, but it won’t even sputter, nothing at all. I thought about pulling the carb and doing a rebuild, since that’s fairly easy to do but I’m at a loss as to why this saw ran fine one day, then two weeks later wouldn’t even sputter.
