sudden flooding
I have a Go Street 400HP system on my 1985 Chevy C10 305CID that I’ve driven for about 1500 miles with pretty much no issues (other than some erratic idle that I’ve been trying to work through).
Anyway, yesterday I experienced an issue out of nowhere that left me stranded. Leaving a store parking lot, I started the truck as normal and pulled out of the parking spot. It then stalled and would not restart at all. I could distinctly smell excessive raw fuel, so I took off the air cleaner and looked down the throttle body. I saw that, as soon as key is turned on and the fuel pump starts that the injector for the left rear barrel appears to be stuck as fully open – I witnessed a hexagonal array of fuel spray that filled the entire barrel with fuel in a couple seconds.
I didn’t have the handheld controller with me, so I wasn’t able to look at anything there, and I had to leave the truck in that parking lot overnight. Is there anything I can look at now, or is this a likely hardware problem?
Did the injector continue to spray fuel or did it stop? There is a prime fuel procedure at key on.
It would help to see what the handheld says. At this point we know the system is priming. That means the unit is on and functioning.
This could be an ignition issue. Nothing to do with the Fitech. Check for spark.
it literally filled the entire throttle body with fuel before we turned the key back off.
Then you have a hung injector. Not very common but can happen.
I just heard back from tech support, they are going to send a new injector for me.
Good to hear. Good people to work with.
Did the new injectors solve your problem, asking because i have the same problem, wating on new injectors.
The replacement injector did solve that problem. Today, however, another one failed in the exact same way. Waiting for tech support response on the new one.
Sent the throttle body back to fitech for ecu.
I think i have the same problem with my go EFI 600hp. I will confirm tomorrow with the fuel pump Prime idea you posted. Anyways, just randomly, my truck.(mild built 350 with a dual plane intake manifold) starts sputtering and runs on about half the cylinders. I have to keep my foot buried to keep it alive. Fitech and my aftermarket AFR sensors both reading about 9-10. Using my laser thermometer i found which ones were missing and pulled the plugs. All drenched in fuel. all other cylinders clean as a whistle. They all have spark. The only thing all the missing cylinders have in common is they all draw from the lower plane in the intake. Makes me think an injector is stuck.
Again, I'll confirm it tomorrow.
