ive searched this alot but i cant seem to find anybody whos having the same problem.

when my car is cold it starts just fine, i hop in it and turn the key and it will just keep turning until i tap the gas. when i do tap the gas it fires right up every time but if i dont tap the gas it will just keep turning.

NOW when my car is warmed up from driving to the store or whatever... it gives me a problem starting every time.... i turn the key and the engine will turn over once or twice and then stop, but the starter doesnt stop, you can hear it still spinning (like when you turn the key and the car is already on) It ONLY does this when its warm ive never had it happen cold.... eventually it will start but usually it takes 3,4 or 5 turns.... sometimes upwards of 8-10 times before it will start but its never left me stranded and its been like this since i bought the car (6 months) and doesnt seem to be getting any worse its just really annoying and frankly quite embarrasing when i pull into the gas station and someone compliments the car, then when im filled up and go to leave it wont start. If you have ANY idea what this could be please let me know as i would LOVE LOVE LOVE to get this fixed. thanks

 

Some info on the car would be nice. Mods and things like that.

 

i have an 84 camaro 40k miles with a 305 in it.the PO upgraded the following:

edelbrock victor jr intake manifold
edelbrock 1406 carb
removed emissions equipment
removed a/c
i was told a mild cam had been put in it but its hard to tell.
plug wires
plugs
and i put a cheap edelbrock circle air cleaner on from autozone.

i just got a set of ceramic coated mid length headers off craigslist and a flowmaster "american thunder" 3" cat back. i have the car at the exhaust shop now getting it mounted on the car and having a Y pipe fabbd up.

besides that shes all stock

 

Did it have the problem before the headers?

When it's warm, and you start it, does it turn over slowly?

Im suspecting a starter heatsoak issue, which is super common with headers.

 

No no its at the shop getting the headers put on now... i left it at the shop overnight. this is an ongoing problems... and no its not a slow crank it sounds normal it just doesnt turn enough times to get the engine going before it "gives out" for lack of a better term.

 

There are lots of possibilities...

 

I would not call any of those upgrades.

When you go to restart have you tried combinations of pumping or leaving the gas alone?

 

If the starter disengages from the flywheel, you need to replace the starter.

 

ill try to put in a new starter and get back to you

 

did the starter work out? im having this same issue with my 91 camaro rs it's a 350 v8. runs cold start no problem i dont even have to use the fan switch or anything...soon as i park and turn it off and try to restart from the next second to minutes later it wont start back up..just cranks and then dies out.

 

havent done it yet, been busy with other projects. im just dealing with it for now, it doesnt keep me from driving it, its just really annoying when it takes 5 minutes to start my car because i have to turn it 15 times

i know this doesnt help you much, sorry. ill try to do it this weekend and i will post results.

 

appreciate ya i was just curious. i went out and started mine again drove around came back not hot no engine light...tryed to start it up 20 mins later and it just kept dying...crank,start..then die...waited a hr. dozed off came back started up no problemo. this is weird

 

If you can hear the starter, but the engine isn't cranking then the flywheel is most likely broken, probably in the inner circle of the flywheel where the bolts are to be specific.

Keep in mind that heat expands metal, and heat creates higher resistance in electrical systems... May not be much, but just enough.

Just an epiphany if that makes a difference.

 

[My 88 350 5.7 does the same can't find the problem.[/B]

 

I had an interesting diagnosis with my '83 Z28 305. The car took around 30 seconds of cranking to start it, turned out it was fuel leaking in the carburetor, which burnt up the starter causing a short to voltage somewhere inside to the point where the starter would sometimes crank the engine when my key was out of the ignition, I had to open the hood and remove a battery cable to stop it, so much fun hahaha, the armature housing coils were black, crispy, and falling apart so I replaced the starter and adjusted the fuel hose. My car now cranks for 5-10 secs because it needs to fill the carburetor bowl up with fuel, and no more demon possessed car starting.

Anyways another interesting long starting issue with the fuel leaking. You know how the fuel hose from the (mechanical) fuel pump came to the front of the engine, behind the alternator, upwards straight to the carb. I had switched the hose to a slightly longer one to come up an inch or two above the internal fuel filter in the carb and back downwards towards the filter and that helped prevent fuel from very slowly draining back into my oil pan or magic hole or wherever it's going and a little through the intake manifold.... OMG that reminds me I should check my oil, I forgot about that... Sh#$

If you have an older carb, it's most likely leaking, I have a quadrajet 4Barrel 750cfm with swapped primary rods and jets from another carb with one size bigger, whooptie doo. Needs Rebuilt Even though the car runs awesome, except for going uphill.... ... Good Luck Hope something was useful out of my findings so far.

 

Anyways if your engine is cranking, good but you need to diagnose if your getting spark at plugs, fuel to the intake, timing to fire plugs at the the correct time, and compression in the cylinders. Do you have a carburetor or fuel injection, and an ohm/volt meter?

 

is the engine turning over normally but not starting?

is the starter motor spinning but not turning over the motor?

is the starter motor turning over the engine too slowly for it to start?
