Thread: Car hard to start sometimes.

Hi

I have a 2002 grand prix gt n/a. Sometime when I go to start the car it takes a few turn overs to get going. Occasionally wont start the first time. Sometimes it seems like it has a slight missfire as well. I have installed new plugs, wires, fuel filter, air filter is good. Checked the ohms on the coil packs as well. I have to check the ohm on the injectors still. Any other suggestions?
Thanks.

Ok thanks, I will put the gauges on sometime this week and get back with the readings.

FWIW, mine is leaking and has been for over a year. The only side effect is the few extra turns occasionally on a hot start. Not worth it to replace it yet.

So this wouldn't cause any other issues such as feeling like a slight missfire on the highway or an occasionally slight stuttery idle upon start up?

Thanks I will look into it any idea what a new regulator costs? Is it much work to change? I will have to ask at my old job when I get in there this week. I am more familliar with working on the old 3.1L. The 3.8 is new to me, haha.

Any ideas on what would cause a slight missfire under load? this is also a problem I am having. it's really only noticible on the highway.

Replaced the started and was good as gold. Started first try like a champ!

Thanks for the input, but sometimes it will start and die right away so I am pretty sure the stater is good. There is no cranking problems at all.

Definitley not a starter problem.

Sounds like a fuel problem to me for the most part. I'd suggest checking that route out first.

I checked the ohm reading on the injectors yesterday, they were all good. I get a different ohm reading on the 3 coilpacks but all are fairly close, so I think they are ok. I also took the egr off and cleaned it out, but it was not too bad so I doubt that helped anything. I should stop by my old job and put the gauges on the fuel system and see how that is. I will try to do that today.

Today I checked the fuel pressure, was almost 50 psi so that is good. I also scanned the car and nothing came up bad, so I have no idea what is going on.
