1991 Dodge Dynasty • 6 cylinder 2WD Automatic • 209,000 miles
Hi, I have a 1991 Dodge Dynasty with a 3.3 liter V6. The car starts great when its cold and runs smooth, but after making a stop and it sits for a bit, when I go to start it, it cranks for an extended time before it starts. After it starts it runs smooth. Why after it warms up and I shut it off and go back to start it does it start hard? Thanks, Rod Harvey

My rusty trusty '88 Grand Caravan has been doing that for many years. Now I just pause between "run" and "crank" for a couple of seconds before cranking the engine. Works every time.
Thank you for the prompt reply. I will try your advice. If it does have a leaking injector is there a simple way to find out which one it is? Its just a work car and cant affoard to put all new injectors in it. You know them fellers arn't cheap.
As an alternative, you have a convenient test port on the fuel rail where you can connect a gauge. Many auto parts stores borrow those kinds of tools for free or rent them cheap.
I was fighting an intermittent stalling problem with my van for 11 months, and for the last month I had a pressure gauge slipped under the right wiper arm so I could see what was going on. I was surprised to see that there were times the pressure dropped to less than 15 psi and the engine still started right up instantly, (usually does that just fine when it's cold), and I had long crank times sometimes when the pressure was still up. Just the opposite of what you would expect. It would appear fuel leaking into the intake manifold causes a flooded condition when warm that results in the long crank time, and that fuel condenses when the engine cools. Raw fuel will not burn, but the air flow during starting causes it to vaporize which promotes rapid starting.
If your engine starts in a shorter period of time, say less than five seconds, I would suspect the regulator is not the problem.
By the way, I have a Dynasty too. Mine gots 4,100 miles on it!
Thank you so much for the help. I appreciate it. I forgot to mention that the car had been sitting awhile and I just started driving it again last friday. It sat for about 2 years. I put new gas, changed all filters, and gave it a major tune up, and it started right up. So between your suggestion and putting me putting some road miles on it, it will straighten up. I bought it new in 91 and put most of the miles on it until my daughter needed to use it. I changes oil every 2500 miles and it still runs great, uses no oil and looks good. Just couldn't part with it or see it sitting, so started driving it again. Again I appreciate your help, Rod Harvey Salem IL
I'm in the middle of Wisconsin. Bought another Dynasty in IL a few years ago. Forgot the town but it was on the east end straight across from Indianapolis, couple hours south of Chicago.
