Problem

[irocelectric93]

So i blew a headgasket in my 93 iroc daytona.... Anyway i get it all back together and try to start it and ...it turns but doesnt start. I checked timing...even went back down to the timing belt...its all good. Then i figured out that the injector...harness thing has to be in a certain order. I think i got that figured out....pretty sure anyway. I checked the colors for each injector...then tried again...better but still nothing. Like i said im pretty sure that i got the injectors right and everything. Its my first time so something may be wrong but...i have like triple checked everything. Everything is stock...except i added an underdrive pulley...52mm throttlebody ported upper plenum and +4 plugs. Just listing in case of any trouble. Any help is appreciated. If anyone knows the harness order for the injectors....that can put in it better terms than my manual that would help as well.

when you remove the Dizzy, it may not be geared right w/ the cam now. I did my head gasket and it took me like 15 tries to get it to start w/o backfiring, then I fine tuned it. If you want to check it, take a timing gun and watch the #1 spark on the crank tab. If you can't see that on the crank, you're WAY off.

Removed the fuel line...its getting fuel to the rail for sure. I guess ill check the distributor....might be 180 off or something. Thanks for the comments

Most problems boil down to lack of:
-fuel
-compression
-spark

A Noid light will allow you to check and make sure the electrical signal for the fuel injector is coming through. If you look in the tech section at www.kmperformance.com, you will see how the injector harness needs to be laid out.

A compression guage is great for testing that the timing belt is on right. Be sure to check _atleast_ one cylinder from each bank...

A timing light will let you know if you are getting any attempt at spark. Still need to check that the distributor is timed correctly. One tooth off and it may or may not run. If it runs it will run HORRIBLY...

To time the distributor, bring engine to TDC. Pull the distributor. The rotor should be pointing over towards the runner for the #1cyl... If you follow the spark plug wire to the #1 tower and then trace it's path to the internal contact, the rotor should be just about be beyond that point.

I have found it helpful before disassembly to bring the engine to TDC, then strike a line (with a marker) on one side of the rotor. That makes it very easy to tell if I have aligned it correctly during reassembly...

Well fuel is getting to it at least till the lower intake. I pulled the lines and turned it over...gas is getting that far. Compression is good.. i checked all 6 cylinders. Spark is great to each plug. Timing....it acts kinda like its out of time....but i have the rotor ...after i pull it to tdc pointing to number 1 on the cap....turns but wont fire. Any possiblility at injector damage? just seems like the problem is at the lower intake for some reason. I have the injector harness on right...i checked kmp and verifyied it was right.
