CHEVROLET SUBURBAN ENGINE

I Replaced A Starter And Oil Level Sensor, And Did An Oil Change And Now It Won't Start Only Turns Over.

Go Out And Try To Start, Start Right Up, Turn It Off And Will Not Restart, Wait 5 Minutes And It Starts. Hit And Miss On The Starting....

So Far, I Have Replaced The Fuel Vapor Canister, Fuel Pressure Regulator, Spark Plugs, Fuel Filter, And Fuel Pump Never Had This...

Truck Turns On But Won't Turn Over. Replaced Fuel Pump, Then It Drove Fine. Replaced Icm, Coil, Distributor Cap And Rotor.
