Crazy no start problem!

[hastyk]

I have a 1993 240sx with a ka24de with a 98 model ka24de head on it (says the previous owner).

I've been struggling with a no start problem here recently and it got really strange. I have the cam timing correct and the Idler sprocket looks correct according to the fsm. I tried moving the distributor around 1 tooth at a time, still nothing. Bought a new harness from wiring specialties, nothing.

The weirdest part is that only the fourth exhaust runner is getting hot... but all the plugs are getting spark.

I'm at a loss.

Thanks for any help.

Have you checked your injectors? it seems like only one cylinder is firing

I was just thinking bout that...can I just take the whole rail out and see if they're spraying? Weird thing is that I bought it with a spun bearing, drove it for a day then took it all apart. Injectors "should" be fine.

Spray maf cleaner in the intake, if it fires up and smotth for a second then it can b a fuel problem

I sprayed starter fluid in the intake...sometimes the motor will hit like it wants to turn over but no full crank and run deal

There are different test you can do to your injectors. Unplug your injectors from the harness and check the ohms of the injectors, it should be around 11-14 ohms I believe but don't quote me on it, check service manual for specs.

Ah. I'll try that. Any other suggestions?

[Primo's Silvia]

Hmm well it could b a couple things try switching the 4th plug to the 1st see if that changes anything

The timing on the cam gears is almost completely correct...you can hear what I'm guessing is the valves click into place. And no, I just figured this one was good since I was driving it 2 months ago. Any way to see if there are any codes being thrown?

[PedroJG]

well it can be a lot of things so try that first and let us know how it goes.

Check ecu for codes. http://www.tamparacing.com/forums/nissan-infiniti-tech/740960-resetting-ecu-pulling-ecu-code-ka24de.html
