Question about 2003 Chevrolet Tahoe
Check the fuel pressure at the TBI there will be a little schreader valve that looks like abicycleeinner tubee where you put air in, When you find that get someone to try and start it and while they are doing that push in on the schreader valve and it should spray gas out of it, if itdoesn'tt then it is your fuel pump.
If their is no spark,replace the ignition module at the inside base of the distributor.If you have spark then it could be a plugged fuel filter or a problem with the fuel line inside the Gas tank.Worst case needs a new engine. spray a shot of starting fluid in to see if its getting fuel. if it still doesn't pop over its an ignition problem. first test to see if there is power at the ignition coil. if yes pull a plug and lay it on the block hooked up to its plug wire and have someone crank it while you watch for spark.(put on the new plug wires),if no spark the module is shot. one of the solutions above should do it. Take care and good luck on it.
