97 Suburban K1500 No Start
Hi all, I'm having a starting issue. My burb is cranking but will not fire. A few days before it would not start I had a hard start. Took 2-3 tries and I had to keep my foot on gas to start it.
My fuel pressure gauge now reads 0. I replaced the pump with a know good used pump, but still no pressure. I'm beginning to distrust the gauge. I'm also throwing a P1351 code that pertains to the ignition control module. I've replaced the ICM and coil within the last 4 months with a separate issue (ended up being a loose crank position wire causing random shut offs). I'd like to see pressure on the fuel pressure guage, so I might buy a new pump assembly (hopefully comes with newer wiring and install ring).
Even if the ICM was bad, I'm imagining it would not effect the pressure on the fuel guage.

Check the fuel pump relay. You can also spray some starter fluid into the throttle body to see if it runs for a few seconds. You also said something about the wiring at the pump to make sure the fuel pump is getting 12 volts.
