Fuel issue solved

[jss06c6]

Just sharing a little info..

Owner filled up his 1990 ZR-1 with ethanol free fuel and drove the car home. Ran great. Went out to move it the following morning and it would not start. It would crank, just not start.

Came in and I could get it to fire, but barely. I could hear the fuel pumps prime with key on.

Checked fuel pressure, only 4 psi.. pulled and replaced fuel filter.. no change.

Patched harness to switch to secondary fuel pump.. 5 psi at key on. Car would start, run about 3 seconds and die... no fuel from either pump..

New pump and sending unit assembly was in the car.. when I pulled the pump assembly, the hose from the Y to the fuel feed line fell off.. remember, brand new assembly in the car.. fuel pressure eventually blew the hose off the hard line..

The plastic hose clamp was positioned below the nipple! Replaced it with a stainless steel hose clamp.. fired right up..

So, don't forget to closely examine all hose connections, even with a brand new unit..20200514_094106.jpg20200514_094118.jpg
