motor is a 4.3L v6 rwd. ok, we just fixed a coolant problem near the cap and plugs. before this it started just fine. it just got a new battery and the fuel pump is fine. we tried drying the cap with starting fluid but still the same problem. it does have alot of miles on it. little over 170k, it also is making a clicking sound almost the same as if you were holding the spark plug wires slightly away from plugs idk if this helps but thank you for any input.

ok the van has spark,tried starting fluid in case of injectors being clogged. no improvement, tried new spark plugs, same nothing about to try ignition coil and distributor cap will see what happends again any input is well appreciated
