I would check for a spark first, but you can pull of the distributor cap and check if the rotor is still turning. If it is not turning, you may have a broken timing chain. If it is turning and there is no spark, it is probably bad spark plug wires, spark plugs, distributor cap, rotor, camshaft position sensor, or crankshaft position sensor.

My 1998 gmc snonma votec wont start it cranks and cranks and after about 20 mins it starts after that i can shout it off and it will fire back up fine then a day will go by and it dose the same thing


You have to check the fuel pump pressure to make sure it is supplying sufficient fuel pressure..Try turning the switch to on but do not start..now listen for the fuel pump to prime the system..it should run for 4-5 seconds the shut off..now try and start..if it is fully primed it should start...note although you are getting some gas dosent mean the pump is ok...sometimes it starts to go bad and then all at once it will let you down for good...have it checked out..good luck

Cranks wont start, 98 Durango


check to see if getting fuel or if you smell gas when cranking if you smell gas you probably have a spark problem which will probably be a coil and or a pickup coil in your distributor replace coil and then distributor. If you are not getting gas most likely fuel pump in tank see if it will fire on starting fluid then replace fuel pump good luck

Fuel pump is most likely the cause. Probably just barely making the required pressure to start. Needs to maintain 60-66 psi while cranking to start.
