[SOLVED] New motor crank no start

[Haedenjames]

Iv got a really weird issue on my speed6. Brand new speed performance motor primed and ready to start but cranks and doesn’t start. Hpfp actual pressure won’t go over 80 even while cranking. Popped the # 1 plug out and it has gas in the cylinder. While the plug was out. I decided to check for spark by cranking it and it fired right up with the spark plug out. Put it back in and nothing. It just cranks and doesn’t even try to start. Wtf? Checked hpfp grounds and pmm ground. And as many other grounds I could see. Also I pulled the hpfp and cleaned and inspected it and all was good.

I had e30 in the tank and the car has been sitting for 5 months give or take. Is it possible it went bad in that time? Just got the car to fire for a split second then die and just crank after that

 

[Haedenjames]

Ok I found the issue just need help fixing it. My injectors are not getting ground. Where are they grounded?

 

[Awafrican]

Little ground by the hpfp is for the injectors / coil pack. posted this image far to many times (or a variation of)

 

[Haedenjames]

Yeah Iv been through all the threads. All the grounds I can find in threads are good. Why they arnt firing. My spark plugs are going so I don’t think it’s timing related. Here’s a log if anyone can see something weird

 

[Awafrican]

have you checked continuity on harness? verified connection at injectors? I had one of the injector pins bent and wasn't getting it to fire after cleaning

 

[Haedenjames]

I’m trying to check as much as I can. I did notice that when I set my volt meter to ohms and put one side on the positive battery cable every where I touch that should be grounded is showing that it’s connected to the positive battery cable?

Are you sure your meter is set properly, or working properly? You should be poppin fuses or suffering CarBQ if power was shorting to ground.

What reading is it giving that says it's connected

 

[Haedenjames]

Nvm once I put the manifold back together it quit showing a connection. Idk what that has to do with it. When I crank the motor I’m getting no gas on the plugs but the ap shows injector pulse and fuel pressure so idk how the hell it’s not even starting a little. I did see a trick that if you take the negative terminal off and connect a test light to a ground and to the negative terminal if it lights it means there’s a short to ground. And it is doing that

 

[Haedenjames]

Ok I noid tested the injector and nothing. Ap shows pulse tho. Does that confirm wiring issue between ecu and injectors?

Make sure the big black resistor thing is plugged in. In stock form, it's on a bracket around the HPFP area. I can get a picture of it if you need.

 

[Haedenjames]

I do have that plugged in. But does the connector that plugs into the resister have only 1 wire?

 

[Haedenjames]

Ok I pulled that black resister or whatever it is off and there are 2 pins on one side but the other side is just 1 pin with 1 wire? Here are some pics. Is that wire supposed to ground to the bracket? How can I test this thing?

 

[Haedenjames]

Alright I didn’t wanna post this because I feel retarded. It was the injector relay was mangled inside somehow. Don’t know how I missed it. Thanks for the reply’s tho guys. Hopefully this helps someone not over look the simple things

 

[Awafrican]

did you snap a pic? glad you got it fixed
