Cranks but no start!
I changed the rotor and the cap plugs and wires. on my 98 suburban 5.7 Vortec drove it for about two months no problems. parked it. The next morning went out crank crank no start no start. Check to make sure there was gas in tank. never had check engine light on ever the entire time ive owned it. Yes the dash bulb does work. Lol. I checked fuel pressure while cranking it. It’s at 66 psi. but when I took my plugs out, I noticed that they were wet n smelled like gas out. Sprayed starting fluid in throttlebody never fired over so I figured it was spark related. Check each individual plug for spark. manually turned motor to the compression stroke to male sure #1 was at tdc Make sure that the rotor pointed to spark plug # one. And it did. coil has spark. my tach moves ppl when I’m cranking so im assuming cps is good tried to see if any play was in dist itself went side to side feeling for or any slight movement and she didnt. Please if anyone can let me know anything else to do it would greatly appreciated.
Is this a good question?
you mentioned smelling gas in the plugs?
try checking the engine for leaks if it has passed the tip of the plugs
if not check the starter, these old timeys do get a little "cranky" with the starter

Just spitballing here but have you checked the distributor cap for arcing or hairline cracks? Sometimes those cracks are very hard to see. In the old days, we would check for these cracks by pouring a tiny amount of gasoline into the distributor cap (off the truck, of course!) and wait a minute while it evaporated. It will take longer to evaporate at the crack and the crack (if there is one) will stand out. I don't know if you have any practical jokers in your neighborhood, but one way to disable a vehicle (very hard to detect) is to remove the distributor cap and use a graphite pencil to draw a ring around it inside. This can short it out. Easy enough to wipe off, though. Good Luck!
