6 cylindrer has trouble starting. You need to cranki it for a long time to start, but once it starts it runs perfect If it sits for more than 30 to 45 minutes it has the same problem but not after five or ten.

Does it start right back up ? Or do you need to let it sit for a little bit ? Some electronic Parts , ignition control modules , engine control modules ,coil packs etc.. when hot ,due to a break down in internal electronics will act like this . The first thing i would do if this vehicle came to my shop , Check for DTC'S diagnostic trouble codes , an check engine sensor data . Coolant sensor problem ,crankshaft position sensor etc... Making Sense of Engine Sensors

sounds like it needs a good tuneup, and maybe a battery! most cars start in about 5-10 seconds, even on a cold morning.if all is ok. good-day!

run the fault codes and check for cam./crank position sensor check that the camshaft is turning ( broken timing belt) Have the CPU reset using a coder reader as the security program may be corrupted from the dead battery

Have you checked base fuel pressure with a gauge yet ?
Sounds like the pump is weak.

install pressure gauge and watch when key is turned off to see if pressure drops to zero if so bad drain back valve in fuel pump replace it or deal with it or could be cheap aftermarket pump and has hard time building unnecessary pressure to open poppet valves between before fuel injectors

it could be the starter or fuel pump what does the car do when you try to start it after you turn it off the first time

If battery and connections are good (it's a big draw,different then other components).Because a bad connection or old battery can sometimes work the starter after it sits,doesn't make it .Some times a starter has a bad spot,thats whe you see some one get under and directly jump it.If buying a battery get at least recommended cranking amp size battery,Larger auto stores check battery no charge (bad joke). Its free google /bing who does a free battery test.Auto zons,pep boys,sears.May even be running a sale.Most switch out battery for fee (no charge*),*Hopefully you will laugh later.

If you mean "hard to start and sometimes won't start at all" because it doesn't turn over or doesn't turn over fast enough you need to replace the starter & solinoid.

timing has to be off , this car is nothing but problems get rid of it and get a honda or toyota

• If you have a carburetor, the choke may not be set properly, or the choke is not working correctly
• The fuel pressure regulator may be operating at too low of a pressure
• The ignition timing may be set wrong
• There may be some type of ignition problem
• The fuel injectors may be leaking
