Haven’t picked up a pressure tester yet but it will spray out pretty far, I checked all the fuses related to fuel or ignition and they were all in working order. I will double check that connecter on top to see if it’s loose, I can hope that’s the issue lol.

I figured this so I swapped the one on the truck for another I had from the other intake and same thing.

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

It could definitely be my ecm but what gets me is it gets fuel but it does have a cel on for code 12 which just keeps flashing after the third orientation 12s so the system is working but it shouldn't be on and I read the ecm can throw random codes. It also did have a rough idle aswell I appreciate you Richard ill have to get another ECM and test it out.

I've replaced everything I could think of but my coil isn't getting spark i got power on the pink wire no power on the white to the tac truck turns over but thats about it, my injectors pulse my fuel pump powers on. I'm stumped on the alternator and dash problem as I can't find anything on the drivers side out of place.

This box apparently its for a trailer? Idk what it would be on a 1/2 ton.

Do you know if there's a ground inside the cab maybe? When I got the truck they had a box under the dash and I pulled it out and It had a ground wire from it

Tbi would make sense why its smoking when the cluster is plugged in. Does the crimping/soldering come factory like this or is this some lovely wiring job someone did? They were wrapped in heat shrink.

So I bought this truck running and driving drove it for about a week and now no spark, I've replaced the distributor which came with a module the coil and wires. Coil refuses to spark checked the voltage on pink wire which was fine also for some reason when I plug my dash in the alternator smokes? I've replaced all main engine grounds so I'm at a loss, 1991 Chevy 5.7
