My grand am has a quad 4 motor. When I try to start it up and the engine is cold, it has a hard time starting. When it eventually starts, there is a smell of gas. If the engine is warm, it starts fine. Does anybody know what might be wrong. I am not sure where to start trouble shooting. Thanks for any assistance.
I had a 95 Grand Am that was so hard to start when it was cold that I was lucky it even started!
And once I got it started I had to keep my foot on the accelerator for at least a minute otherwise it would stall!
At least I now know that I wasn't the only one with problems!

when was the last time you change spark plugs wires and plugs? If you haven't for the last couple of years, I would start it now.
I have seen ,in a couple of rare occasions,one on a k/1500 pickup,and one on a 96 Grand Sport ,where a weak fuel pump gave those very symptoms. I would have the fuel pressure checked while the engine is cold. I may be wrong,but I dont think a quad-4 has plug wires,arent they built into the cover? That would eliminate the damp wire theory.
Hi, I had the same problem with my 1993 Grand Am 2.3 4Quad (now with 151k miles)
I also had to press on the accelerator to keep from stalling. I kept my left foot on the break and right foot on accelerator as I shifted from park to drive. I drove for like, 2 miles or so before the engine warmed up enough where it wouldn't shake and stall out.
What I did to fix?
Paid to change the spark plugs, ignition coil, fuel filter, and have the top engine cleaned and fuel system flushed. Cost me $815
Before that, I went quite awhile between tune ups and changing spark plugs.
Well, that was more than a year ago. No problem since.
Thanks for the assistance. I will be looking at the plugs and boots next. I did clean the Idle Air Control Valve today. I was carboned up quite a bit. It seems to be starting better.
I last changed my plugs about 6 months ago. I haven't changed the boots though. I will probably go get a set in the next week or so.
