Where is the cold start valve or injector located on a 1998 isuzu hombre pickup?

buy a can of sea foam motor treatment at a auto parts store pour it in the gas tank with at least a half tank of gas disconnect the negative battery terminal for about 15 seconds reconnect, than start car and drive it should solve problem with hesitation if the problem comes back check for a bad injector are fouled spark plug, you should put sea foam or other brands of injector cleaner fuel conditioner in your gas every other fill up ethanol gas fouls plugs and causes injectors to clog because of the carbon that it forms on your pistons valves and intake runners, sea foam will cure this problem

Not sure on yours (read a shop manual) but most are located low on intake below the throttle body.

over fuel from bad needle and seat , or leaking injector seals you didn't mention make model year or type of equipment so that answer is the best you get

You need to rebuild the carburetor or clean the choke linkage and make sure the choke valve closes cold.

try running sea foam to clean injectors. put it in your gas

is it distributer or coil pack style if so id check into them either one could be getting wet

Fuel pressure regulator is going bad, basically you are getting to much fuel into your cylinders and are causing hydro lock

Add fresh gas and a can of Sea Foam, charge the battery, check the brakes if you plan on driving it do these things and you should be good to go.

Run a can of Sea Foam injector cleaner through your fuel system.

should be between the crank dampener and the block, i mean they are all relatively the same on all cars should be the only wires running close to the crank dampener
