Hard starting
I've got a 1997 chevy suburban with 7.4L (Vortec - 454), and lately it has had a hard time starting. The battery and starter seem fine, but it has to crank for a while before it starts.
The spark plugs and wires were recently replaced. What should I look at first? Fuel pump, fuel injectors, etc.? Please help if you can. Thanks!

Re: Hard starting
Check the fuel pressure regulator for evidence of fuel in the vacum line. If you find any, replace the regulator.

Re: Hard starting
The last reply was correct. Replace the regulator. I have a '98 7.4l that I just replaced and it runs great now. It's a lot of work on the 7.4L.

Re: Hard starting
Mine got to where it would never start on the first crank unless I cranked for 10 to 15 seconds (not good). I noticed that if I cranked for just a couple of seconds, stopped, cranked again, it would start right up. Ended up being the cheapest part out there....fuel filter. Hope you get as lucky as I did.
