Rb26 Not Starting. Help Needed

[Julz89]

hey guys got a quick question done a engine swap on a 94 gtr (r32) and she isnt starting. She has fuel pressure but no injector pulse and spark and she has constant power at the cas plug. what would be some things to look for as it is drivin me insane. cheers julz.

does it crank?

[Julz89]

yes it does crank

Engine swap? Like for like? Retained original ignition/ecu electrics? Electrics working OK before swap? Electrical harness/sensors/fuses not farked during major surgery? If ans="yes" to previous four questions get Skyline savvy autospark involved, if ans="no" make ans="yes". If still no go then back to "Skyline savvy autospark". Else keep pushing s#$t uphill.

Hope this helps, best of luck with it all.

Cheers GW

Do you have power to the injectors? Do you have power to the coilpacks?

Get yourself a good quality LED test light and probe into the pink trigger wire at the coil pack to see if the ECU is putting out a signal. The fact that you have neither injector pulse or spark usually means it's something to do with the CAS (trigger)

You can check the 1deg and 120deg signal with the test light also.

Turn on the ign and check for power at the cas. Once you know the power feed, the one next to it is the earth, the next is the 120deg signal and the last is the 1deg signal. Could be the other way around on the last two can't remember. But it doesn't matter, as long as you are getting a pulse out of both of those wires while cranking. If you are, then look to the ECU and make sure it's all plugged in correctly.
