I have a 97 balzer that runs fine for a few miles then just will not take gas. It will idle fine and you can spray carb cleaner in the intake tube and it will take fuel fine. You can also turn the ignition off and start it right back up and it will be fine for a couple more miles and then do it again. The cel is not on so I have no codes. Ive replaced the distributor cap, rotor button, plugs, wires, crank sensor, cam sensor, tps sensor, coil, module, maf sensor, fuel pressure regulator, and spider all from a donor vehicle that ran fine. Nothing seems to help. Any suggestions?

 

have you tried replacing the fuel pump and fuel filter? the problem could be that the engine is not getting the fuel? just a suggestion i could be completely wrong lol

 

Is the CEL (check engine light) on?
