2000 chevrolet express van wont start

not knowing the condition of you suv, replace fuel & air filters, very important, replace distributor cap & rotor, spark plugs & plug wires. that should do it, good luck

the high humidity (water) is attacking your electrical starting system, whens the last time you changed your spark plug wires , distributor cap & rotor ? how about your fuel & air filters ? cleaned your battery terminals ? try it , it will help !!!!!!!!!

There is a good chance your injectors are not firing. I would suggest cranking the engine without the air filter housing on the throttle body and see if the injectors are squirting fuel. If not, I believe they are fired off a signal from the distributor pickup.

check fuel regulator, fuel pressure, could be bad sending unit in fuel tank, change out fuel filter

If you are Getting SPARK and FUEL PROPERLY, The Engine HAS JUMPED TIME and Requires TIMING CHAIN Replacment to Correct the NO START Problem, BE SURE of GOOD FUEL PRESSURE and SPARK Before Proceding.

try to spray some carburetor cleaner inside where the air goes in the engine...it will clean the system and it might start...
press some gas when you try to start the vehicle...
good luck!

Start with fuel system. Listen for fuel pump humm at fuel tank No humm check wiring to pump for power. Then check for spark at plugs and wires. Remove wire from coil and hold near engine and see arch when you crank. No arch. Replace ignition Modular inside distributor cap or cap or rotor

I would chech the ingition module inside the distributor. It's a little black box on the bottom(inside). I'm assuming you have the correct fuel presssure coming from the fuel pump.

Sounds like the fuel pump went. Check for power under the van at the gas tank for the fuel pump. You need 2 people to do this,the pump will only power up for 5 secs/key cycle unless the engine is running.

Have you checked the fuel filter? Have you changed it EVER?
