98 c1500 5.7

[Dc8610]

hey guys sorry if this has been asked before. I have a 98 c1500 350 5.7 and is it normal for this year engine to have to press gas pedal to start? on cold starts it will start up fine by itself without pushing gas but on a warm it cranks until I give it gas most of the time. when driving it does not hesitate or sputter it drives like a brand new car. thanks in advance.

It should be able to start by turning a key like a sum what modern truck. It's not a Carburetor and sometimes it may crank a long time indicating a leaky fuel regulator.(not normal) Now sometimes you can turn the key to the on position to prime the fuel and then start the motor.

I let it prime for about 5 seconds but I still have to give it a little gas on warm starts to get it going.

I would do a fuel pressure check. Does it miss or run rough

No it’s runs fine doesn’t skip a beat.

NOT normal.

Verify fuel pressure, connect a scan tool and find out what the computer is trying to tell you via the data stream.

Mine did that right before the fuel pump went out. After I put a new pump in that never happened again.
