sr won't start - Zilvia.net Forums | Nissan 240SX (Silvia) and Z (Fairlady) Car Forum

9DSX_DRVR · 08-12-2006, 04:23 PM

I did a search and all have the same situation but with a little difference so I am having trouble fitting my situation.

-I just put in the sr20 and hooked it all up myself
-I wired according to "Heavy Throttle"
-I double checked the wiring.
-The motor cranks just fine and I get power to everything
-I put in new spark plugs and I am getting a spark

-there are 2 plugs with 2 different ends on them that I don't know where they go. The are on the harness right next to the firewall, just after the ignightor, they are both 2 wire plugs, one is an L shape (it looks like the plug that goes into the MAF) the other is a standard square plug.

HELP guys

could you take some pics of what they look like for us, it'd be alot easier than trying to explain them, is it getting fuel? like if you keep cranking it can you smell it? if not make sure that you've got that wired correctly. But post a pic and i can or someone else can help you alot easier and faster

he's asking if you smell a rich gasoline smell from the exhaust when you're trying to start it.

I mean by "wired correctly"

did you rearrange the wires at the 2 plugs behind the battery? and made certain that it is wired correctly? there are about 2 plugs that don't go anywhere. if everything has been pluged up, then your ok. just double check and even have someone check behind you on your wiring....using Heavy Throttle's guide.

here are the pics of the 2 plugs.
The other plugs (the ones behind the battery) are wire correctly according to HT.

I am getting a spark but not real strong.
So, I have other questions.

-Could it be out of time? especially since I have never messed with it.
-could a low spark not let it start?
-would a bad ECU allow a spark and not run?

Let me know

dont think too far ahead, troubleshoot step by step
reset timing, prime the motor and try again
