The weirdest crank no start ever!

Post by i_slide »

Alright so I got a buddy's 90 ka24e 240sx that I had to do some work on. Long story short after I replaced the engine with another ka24e I'm not getting this thing to run on its own.

After going over the typical I came to the conclusion that its a FUEL issue. At first the injectors were not firing during cranking, I had to take each injector clip out and clean them all so they can fire the injectors. So with the rail still out, i verified that upon cranking the injectors were firing.

Now this is where i'm lost. I put the rail back in and it still doesn't start. If i pour gas into the throttle body it starts rite up and runs until the gas i poured in is used up, I'm lost as all hell. If the injectors are firing with the rail out during cranking then why wouldn't it continue to fire with the rail bolted back down to the manifold to start this engine?

Any help will be good much appreciated, Thanks

Are the fuel lines switched? Return line goes to the regulator

I checked that also at first. Thanks for the reply but I solved the problem.

The injectors had to much corrosion on the clips that they were not getting enough electricity to fire correctly or rapidly enough. So what i did was cleaned it off with a razor and brake clean and like magic it fired up.
