Have a chevy malibu that would not start up, it trys to but no firer maybe the fuel pump might be bad.

Basics: spark,fuel,air,compression make an engine run.does it have spark? take a plug out put the wire back on it, ground the body of the plug to metal on engine. have someone crank it over, spark?y-n?yes ok move on to fuel. no, check for spark at the distributor cap.eliminate possible problems one by one.check for fuel flow. take air cleaner off the carb.if carbureated. pump throttle while looking down carb. throat.fuel should squirt into carb below choke plate.{hold it open while looking}fuel? y-n? no: check for fuel flow fron gas line into carb. remove fuel line andcatch fuel from the line in a container while helper cranks engine.no fuel, probably bad fuel pump.etc. good luck
