I replaced the radiator (it was cracked) and while I had it out I replaced the water pump and plugs. Now it will not start. I have spark and gas. It sounds like it wants to start but it just won't catch. It is a 2002 Sonoma with the 2.2L

If the rad did indeed crack,was that because it froze solid?

Yes. It ran fine when I started the work. No oil in coolant. No coolant in oil. Cylinder pressure is good and consistent in all four cylinders.

Just my thought,s if it ran before you replaced all that you said,nothing but plug,s could lead to lose of fire,now i can,t sat this for sure,but check your plug wire,s may be you placed them in wrong order?

Thanks. I checked spark at all plugs and I have spark. I can smell gas. It won't even fire when I use starter fluid in the throttle body.

You still did not answer the question - - did the rad freeze?

Yes it froze. I said that in an earlier post. Not sure why that matters.

thermostat in radiator dead like this thread? guessing..idk.
