The starter is wearing out...check before you get stranded. (Bad spots on the bendix) Hope this helps.

SOURCE: Car cranks but won't Start

It sounds like your alternator mat have gotten wet. there is usually some sort of cover under the alt. I would get that and the battery tested. They can be tested while still on the car. If it won`t start you would have to get them pulled and checked. Usually free of charge.

97 GMC Safari. It is taking a long time to start. cranks and cranks... about the 3rd or 4th attempt, it will start. This problem just happenend.. One minute it started on the turn of the key... then, this...


Replace the FUEL PUMP RELAY. Its located in the under hood relay center. This relay primes the pump with the key on, about 2 seconds, then the pump will not run until the engine has oil pressure, then the fuel pump is energized.

It takes a few tries to start the car. the car cranks, I turn off and then on again, may crank again before finally firing.


Sounds like a fuel problem, turn the key on and listen for the fuel pump to run, you should hear a humming noise for a few seconds then it should stop. The pressure regulator could be weak/check valve or injectors may be leaking by and causing fuel pressure to bleed down. Any other drivability issues/problems.

Get a DTC scanner and see what it says...in the meantime, check that fuel pump relay and fuel pump. The humming sound is probably the heater blower motor or part of the HVAC system winding down after disconnecting from power.

Turn key 4x to build pressure, on 4th try complete Start seq.


is the engine actually cranking when it doesnt start or do you hear just one "click" each time you turn the key? if the engine is cranking, i would suspect a fuel problem, possibly fuel filter if it wasnt changed when the fuel pump was done. if it is not cranking and you hear one "click" upon turning the key, i would suspect faulty starter or connection problem.

Car wont turn over when started


When you turn the key to full electrical power (right before you'd crank it), do you hear a hum from behind you? It'd be the fuel pump, and it should run for a few seconds. If it does, and you have no cranking when you turn the key, check the starter relay - if it's shot, it won't allow power to the starter, and the car won't crank. If you don't hear the hum, check fuses and relays for the fuel pump first, and if they're OK, you may have a dead fuel pump.
