Soooo, I have spark, air and got my fuel pump issue fixed due to a broken purple/white wire in the chassis and have fuel at the rail, but now have no power at the injectors. I have found a few connections not hooked up in the loom, but can't find where they attach. Checked all fuses, and there good. Also, swapped 14cux with my 1995 station wagon and it fired right up, so I am ruling that out.

Any direction would be helpful.

Also, I might have my timing 180, so I hope my video will help with that.

No start after a build is always better than a start and a catastrophic stop.

I don't know which EFI setup you have, but I believe all of them require a connection from coil negative to the ECU before they will fire the injectors.

The problem may be that it’s can’t handle being so clean…
Double check plug wires are going to correct cylinders. If so, are plugs wet with fuel? I’m pretty neurotic about plug and wire changes. Always starting the truck after each new plug and wire…

 

[bboldt3]

Agreed!!!

Even if I’m getting spark, something might not be hooked up? All plug wires confirmed hooked up correctly.

I’ll pull all plugs, but cylinder 1 and 4 were dry as a…well you know

Reset the inertia switch?

Pictures & color codes to the loom connectors that you can’t find homes for ? If you have pressure @ rail & spark this should be very simple.

I'm just going to commend you for even getting to this point... nice work!

 

[waveridin1959]

Did you try pulling the dizzy and cranking the motor 180? The injectors wont fire if the motor doesnt turn over.

Reset the inertia switch?

Inertia switch should cut power to the fuel pump. He says he has fuel at the rail.

I jumped the inertia switch to rule it out, ended up being fine.

Thanks pbfender15, its been a bigger than expected project!

Waveridin, not sure I understand your comment... are you saying if not timed right it wont fire injectors?

Ben

 

[waveridin1959]

I believe if your 180 out and it doesnt fire on the first few revolutions the Injectors wont pulse. I think they fire intially, but quit if the engine doesnt start. I cranked and cranked for a day going through every troubleshooting step until Lynch asked me if I was 180 out.

 

[bboldt3]

Ok I can pull Dizzy... Is it 2 rotations of crank or one... Cant remember what ive read.

Ben

 

[waveridin1959]

if you pull the cap and your lined up at 1 and the crank pulley is on T, then pull the dizzy, rotate around once and then get put the dizzy back in pointed at cyl 1. Do you have a timing light?

 

[bboldt3]

Got it, one rotation. Yes I have a timing light, I will get this done over the weekend. Hope it works!!!!!

Be sure to prime the system before cranking it again. I just rebuilt my motor and will be trying to start it this week as well.

 

[bboldt3]

Prime I.E. the Oil Pump?

Ben

 

[waveridin1959]

Yes. With the Vbelt setup you can prime the motor with a drill. There should be plenty of writeups on how to. I have a serpentine setup so I just have to start the motor and hope for the best.

There should be white wire in a black sleeve coming from the wiring harness to the mass air flow sensor on the driver side valve cover that connects to the negative side of the coil. That tells the ECU to fire the injectors- when the coil is firing. I

 

[bboldt3]

My wire is solid white and is coming from drivers cover? I also removed the amp relocation kit so maybe something got hosed.
