I have no codes spewing out of my ECU and I had it diagnosed with a Snap-on Computer and still nothing. All of my sensors are functioning up to par. I can't seem to get my car started. It turns over forever but won't start. Theres no spark. I smell raw fuel after 5 minutes of trying to start it. Could my ECU be bad? Help please!

 

Could be your ECU but I doubt it.

My buddy's I30 did the same thing. No start, just crank and crank with lots of fuel. No CEL light, no codes. We finally towed it to Infiniti after 2 days of troubleshooting. ****ed me off that with the help of the org we still couldn't get it fixed.

Turned out to be one of the crank sensors. It never threw a code, but it wasn't working. There are 2 crank sensors, one is REF and the other is POS. The Haynes manual describes how to test them with an Ohm meter. I bet you one has failed and thats what's causing your no start condition. A few on here have had the same problem with no CEL or codes thrown.

 

Does it crank very fast? If so it might be a bad timing chain.

 

A bad cam position sensor (or unplugged one) will cause the spark plugs to not fire as well.

 

I failed to mention that I had a similar problem in the past in which I replaced BOTH crank sensors, as well as the Cam position sensor. These parts were still under warranty when I had my current starting problem so I had my mechanic replace all 3 sensors again and still nothing. Sorry for the previous lack of info guys, but thanks so far. At least your eyes are looking in the right direction. Any other help would be pricelessly appreciated.

 

i might have an idea what your prob is. Ill need a bit more info and ill need you to test a couple things as well. Get back to me if your still stuck on this prob. Private message me or email me...good luck. lata
