2004 L300. Why doesn't it restart when weather is hot and humid?

lots of reasons. 2.2L or 3.0L V6? no engine told and is and engine question , no VIN and if told we tell you what's under that hood. Driving to KEY West FL. huh, LOL !!!!! not told is does it CRANK ok fast or starter is dead.? or cranks fast but will not start,. hot. << guess yes. so in 18 years no tuneups done??? spark, filters ,belts ,fluids? all spark parts bad, they hate humidity when bad, for 100years. 2.2L has 4 cops spark coils in large single unit. it may be bad or just those old old spark plugs under it. and 4 boots bad too. V6. uses same funny unified coil pack, but 2x3 and same exact answer packs , boots and spark plugs bad. that is about it, but no starts have 50 causes and lots of tests to find but a tune up is always good to do , (ignored a long time)

2004 saturn l300 3.0 diagnosed #3 spark plug misfire. installed new plugs and coil pack that goes to #3 cylinder. now not getting spark to plugs. car won,t start

I'm guessing you had to remove all the coil to put the new one in. When you reinstalled the coil packs, did you make sure your they are grounded?

check the fuse--you probably brushed the 'hot' wire against a metal bracket and shorted the circuit and blew that fuse.

2004 saturn L300 shuts off after you turn on in 4 minutes. what the problem?

the engine valves must be the culprit here, the input valve must not be moving up and down or maybe leaking causing the improper supply of fuel to the engine resulting in start-up and shut off problems.

The red arms on the gauges do not light up on a 2004 saturn l300

All of the instrument cluster functions are handled inside of the cluster. So for just the gauge needles not lighting up, you will need a replacement instrument cluster.
