Cranking but no start

[Supra-Kid315]

I'm new 2 supras and the 7mgte engine and I have been piecing a gte 2gether so finally got wat I needed and droped it in a week ago, I started 2 reconnect everything and put everything bac 2gether. I have followed everything step by step according 2 the service manual. but when I went 2 go start it all I get is cranking, I checked 2 c if the coils are getting power and they are, I checked all fuses, checked 2 c if I'm getting fuel which I am, I also did a 5spd sway and slpiced 2 wire 2gether according 2 wat I read in a thread (white and black wire splice 2gether and now ecu thinks its in park so i can start it), 2marrow ima check the injectors 2 c if they are opening up. and the injectors are getting power.

any advice on wat I should check would b great.

thanks,

for fucks sake TO TOO TWO BE SEE.

do you have fuel? how long did you try to crank it? you didnt hear even 1 cyl fire off?

The key thing you should be looking for right now is whether the tach moves at all when you crank the engine

 

[Supra-Kid315]

yea I notice the tach will move a little bit when I crank it, what does that mean?

 

[Supra-Kid315]

yea I'm getting fuel, but I don't hear any spark plugs firing or anything.

This means the ECU is getting the signal from the CPS

Pull a spark plug at a time and turn over the engine...see if you're getting spark on all your plugs

so that's good news that the ecu is getting a signal but I'm going to check for spark and see if my injectors are sparying first thing in the morning

ok turns out i had the wrong injectors in the car (7mge injectors):3d_frown: so im going to swap them out and also i dont think i have everything grounded for the coils and stuff so ima get to that, anyone have a picture of where the EFI grounding points are
