Slow starting GT

My 1991 GT has one annoying issue that is starting to bug me. When I turn the key to start it it will crank over about 8-10 times and not start. Then I barely step on the accelerator, turn the key to "start" and it usually starts on the first crank. Tried stepping on the accelerator on the first attempt to start it and it just turns over and doesn't start. The second time is usually the charm. Kind of reminds me of an old Chizler Motors (Chrysler) car I had. It wouldn't start either. 1st, 2nd, or 8th time. Believe it or not, the car was a 1968 Hemi-roid Charger (yes, a real Hemi, not a clone) The problem with the Hemi was a weak ballast resistor.

The car has had a fresh tune up, timing is set at 10 degrees, all new filters, plugs, etc. I've replaced the fuel filter, checked the fuel pressure (about 38 pounds with no drop) and generally replaced most items that wear out. The car idles great, runs out strong, and doesn't miss a beat.. Any ideas on what to do now? By the way, the car is bone stock (less air silencer) and has 72,000 actual on the clock.

Re: Slow starting GT

Check the battery and all the grounds and positive wires to the starter also check for a phantom load by hooking a set light to ground and contecting it to the positive able if it stays on you got a phantom load and well that can be easy or a pain to find depending on what it is and where it is,but more than likely you would have noticed this by a dead battery by now.Also the starter might be showing some age if its still the original one that come with the car or a cheapy replacement.
Mustang wanted for here...

Cool Re: Slow starting GT

try this turn the key to on and wait till the fuel pump stops turn it off and do it again wait till the pump stops again then crank it over. you may be loosing fuel pressure this will allow the pump to build it up. If that works you will need to find out why its loosing fuel pressure . ex. Bad check valve on the pump leaky injector bad pressure regulator fuel line leak....... hope this helps

Re: Slow starting GT

Does it do it more often when the car is warm, i.e. you've driven it for a while, cut it off, and are now trying to crank it again?

If so, it's most likely the starter.

Scary stuff.
