1. I got a 97 integra Bone stock LS Car start and all its running on 3 cylindera
but #1 cylinder is not firing i pulled the injector clip off and no change
Replace the injector and still not running. #1 injector clicks

2. Then I have another integra 2000 model with GSR swap.
Problem is car will run but once i let go off the key it shuts off immediately.
I have to hold the key on crank position for it to run once i let it go it shuts off right away.

Thanks in Advance

 

Is the first one getting spark?

The second one sounds like an ignition switch problem.

 

I second the second.

Spark should be the next thing on the LS as Sol said. How many miles on the LS motor?

 

Yeah i was thinking the ignition switch also but it just happend out of nowhere

If there's no spark on 1st cylinder only what could be the issue?
Dizzy? Wiring?

 

Update fixed the LS toook apart the dizzy and it was the rotor screw that came off.
thanks guys.

gonna try and clean the ignition switch if thats the prob if not. switch with a goood working one.
