Hello, I have a 96 C1500 with the 5.7 vortec, I’ve done a lot of work to this truck replaced the engine and got it running. Drove the truck a few times and it wouldn’t start, Fuel pump was whining so I dropped the tank replaced the fuel pump I’ve checked for power at the connector for the pump with a test light I get power on the pink wire. I hear the pump come on and I’m getting fuel spraying from the valve (Haven’t check for pressure reading because I don’t own a gauge) I’ve checked all the fuses related to fuel or ignition and they’re all good. I have not replaced the fuel relay but I assume if I’m getting fuel then it can’t be bad, I also replaced the fuel pressure regulator when I installed the engine) my only guess here would be my spider is bad and I’m hoping someone can point me away from that, I do have another intake with 114,000 miles on it but I really don’t want to pull the motor apart. Any suggestions are helpful and I appreciate it. -Dion

 

Your title says it starts with starting fluid - does it stay running once it fires?

 

No it immediately dies

 

When my 93 5.7 acted like this (twice now) a new ICM in the distributer fixed it

 

I replaced the icm but this model has it on the outside bolted to the intake, I was thinking the same thing because I had a 91 that was doing this.
