What ECU and harness setup are you running?

LS1 from Turnkey engines has been sitting for three years in a Jeep project have spark only getting fuel to two cylinders has new fuel pump and plumbing? Could six injectors be frozen? Was run with old gas.

Have not checked injector pulse yet? What else should a check?

Thanks

Check injector pulse with a test light at the injector harness, see If your getting a light (pulse) at all 8.

Also - if those injectors have been sitting with fuel in them for 3 years stagnant I'd definitely send them out to be flowed / rebuilt and dyno'd. That's the easiest way to kill an EFI motor, have one or more injectors clogged and lean out cylinders.

I use FIC (fuel injector connection) for all my injectors, but Alexi at Boostpower can flow them for you also. Not sure where your located

I have had that happen. Go to start one and no fuel. All eight injectors were full of stale gas. cleaned and flowed them and fired right up..

This. I bet gummed up injectors.

Noid light showed pulse on all eight pulled injectors tested with 12v and air no go

Turn-Key engines had new set of eight on the shelf costs less than one Mercury racing injector!

Thanks for the help:thumbup:

:rolleyes

A few hundred maybe??

Every ls swap I do, I figure in cleaned injectors. Jim at Bones fab has a injector flow bench and cleaner and has done some sets for me.

Just because i have a dozen or so on the shelf doesn't mean anything.. We are actually doing a ls9/t56 powered 64 chevelle and a Lsa/4l80e 72 Olds Cutluss right now.. And I am about ready to drop a 6.0 in my shop truck project..

Check your connections for the injector circuit, I've seen erratic behavior in that past where the weather-pack connectors aren't so weather proof.

Installed the new injectors and lit right off:thumbup:
