#4
MY dads s10 pickup is either at 0.45 or 0.35 I dont remember exactly... I can check rock auto and see what they sell there plug gaps at for VIN X
Edit: rock auto sells plugs gapped at 0.60.... I never heard of it being so large... I will look into this more.
Edit2: Vin w takes 0.45 and Vin X takes 0.60

So wait... Rock auto only sells plugs gaped at .060 for vin W. Did you accidentally reverse the X and W Gio?? Or should i be out there regaping the plugs i got from them last year lol.
Edit: I just did some research and the proper plug gap should be in the emissions sticker on the core support. For Vin W it is .060

CMFI gap is .045 CSFI gap is .060
Something to check for your long crank is: With the fuel pressure tester connected, jump the pump prime connector several times and watch for the pressure tester needle to jump up immediately when you jump it. I've seen a few where the needle doesn't jump right away when the pump is activated, turned out to be a dead spot in the pump motor armature.

Did you try it several times? With the screwy ones that I found, the needle would deflect immediately sometimes, and other times it would take maybe a half to one second before the needle would deflect. In fact, with a couple of them, the pump motor would start immediately but the pump didn't produce pressure immediately, (bypassing inside the pump). If the engine is cranking when it screws up, the injectors will pulse and squirt fuel until pressure drops below ~43psi, (poppet valves do not open below ~43psi). The engine might start and stall immediately, or it might not start at all.
