Me and some friends were putting the finishing touches on my SR swap today. after we got it all together and the moment of truth came, I turned the key and the motor will not turn over. It cranks and at times it seems like it wants to fire up, but it mostly just cranks.
My fuel rail was bent when they pulled the motor in Japan, and when I crank it the seal blows out on the #3 cylinder injector. I knew the fuel rail was going to be a possible problem, and now I know that I need a new fuel rail, but I the car should still at least start, right?
There is definitley fuel still going through the other injectors, and I am getting sparks in the coilpacks on all 4 cylinders. I shocked myself numerous times trying to determine this.
Mo was helping me, and we had his s13 SR as a reference, so I know that all of the vaccum lines and hoses and stuff are in the right spot, and that all of the major stuff is in the right way. I am thinking that it's just something small and stupid that we forgot to do, but we just can't figure it out.
I am not sure what to do, or even what else to do to try and trouble shoot. I know it's getting fuel, I can smell it. And I know it's getting a spark because when I sprayed some starting fluid in there, it backfired out the throttle body. and I know it's getting air, because I'm still breathing.
Any Suggestion, besides making this post shorter
newly swapped SR cranks but won't turn over
the fuel is hooked up the right way, I checked it to another SR that was parked next to it. I am going to do the timing tomorrow, I think (hope) that is probably what it is. it was probably messed up from doing my metal head gaskett
Now I all I need to find is a stock fuel rail. Anyone know where I can get one?
does anyone who upgraded to top-feeds have a stock S13 SR fuel rail?

I couldn't work on it today because it was raining. I ordered a new fuel rail and got it shipped next day, so once it get's here i'll slap it in and work on the timing. I have convinced myself that the timing is off, the way it sounds when it cranks leads me to belive that. 180 degrees off could explain the backfire out the throttle body. The engine is a type-X and I have the correct ECU/harness I made sure of that.
Looks like it's gonna rain here on the East Coast for the next few days, but i'll def. keep everyone posted when I figure out what the deal is.
Nils, you were only getting spark to one cyl. when you had the wrong ECU right? I am definitley getting sparks to all 4. my ECU is an E5

You shouldn't just "flip the CAS 180 degrees", what you need to od is make sure it's set right, and that the cams(both oft them) are timed right. To check the cams you'll need to pull the rocker cover, crank it over slowely until the shiny links on the timing chain line up with the mark son teh cams gears, and #1 piston is at TDC, on compression stroke. Then you need to set the CAS right. If all of these things aren't right then it won't start. You alos risk bending valves if the cam timing is off by much.
My guess is that when you did teh head gasket the timing chain slipped a tooth or two on the crank pully so when you put it back together the CAM timing is off.
I hope this helps

flipping the CAS was just a shot in the dark. If the cams were aligned right and the CAS was off by 180, then that would have fixed the problem. But, since it did not work I took off my valve cover and found out that the cams are indeed off. The guy who did my head gasket told me specificaly that it was timed right, so I took his word for it, but I guess he was wrong. He is going to come by later this week and do it. I hope that's the only problem.

riiiiight
:ylsuper it was the timing, I messed around with it a bit and she fired right up. this rules:ylsuper
btw, the guy who put my head gaskett on totally disreguarded the shiny links and just threw the chain back on there. I had to shine a light down #1 cyl to find TDC, and looked at the cams to see if the marks were at 10 and 12. my timing is still probably a bit off, I don't have a gun. but she idols like a dream, purrs like a kitten.
