Another Intake question Fuel Injectors quit

[bluchev]

sounds fishy man.

id say either someone dicked up on the install somehow or you just got unlucky and the injector decided to take a shit on you.

if those poppet valves arent plugged in all the way i would imagine that would create a driveability problem. so did you do all the work or did you only do some of it?

A vortec 5.7 has 8 individual injectors all located in one central spider looking thing. The single injector with 6 legs was in the early vortec 4.3 in the s10, blazers, and jimmys.

I put in an intake gasket and everything was complete. It would not start because I had the distributor in wrong and two wires crossed. So we towed it in to get the distributor installed.

get the fuel pressure checked out. if the fp is lower than 45 psi the injector wont fire.

Except that I have replaced individual injectors out of the spider in those. You used to be able to order the injectors individually from GM. Each injector has its own set of wires if you look carefully in your picture.

Right on. The shop was just saying that you can buy an eight pack for about the price of three individuals, and the labors the same.

I think they are just trying to make a buck since I brought in a vehicle I had already worked on. I do it myself on plumbing jobs. If someone else starts the job and then calls me I pretty much tear out what they did and them start over and charge accordingly

Those injectors are known to be trouble, but if it was running fine before the gasket replacement, I would look elsewhere. Especially if you already have wires turned around and the distributor goofed up.

hmm , ive only heard of replacing the whole works. i dont see why youd only replace one or two, when the others are probably not too far behind.

where are the wire youre talking about( in the first picture).

That sounds bad. I really didn't have it goofed up. I just haven't had time to finish the job and the old man wanted it done.

The repair guy says he is pulsing the injectors one at a time and two or more are not opening. ?? Just seems like bullshit but possible I guess.

He means each injector has it's own wire. The harness on top has 16 wires in it. and the connector plug into the top of all eight injectors.

well if a couple of them arent working i would replace the whole thing. to prevent future problems. either way its gonna be expensive.

That MFI conversion looks pretty interesting. Might be worth looking into.

1 with a k behind it

[bluchev]
