I went back out and installed another ECM Plug and the new ECM I started out with. Having to wiggle the red wire to get contact was just a future problem or in hitting the first bump. I now have a red light on the neg side but it is not as bright as the pos side. still no fire.
When I was...
I had to get into the column to replace a broken turn signal switch anyway so I went ahead and added a new ignition switch. Still no power to the neg side of the coil with the key on. I installed an older ecm and I get a green light from the neg side of the coil to the neg side of the battery. I...
No Sir I do not have a procedure but willing to learn.
I will check the ECM ground.
Would the pos side of the coil get power if the ECM was not grounded?
The distributor is rebuilt but that doesn't mean anything these days. There is no power at all getting to the distributor. No power on the Neg side of the coil to power the distributor.
I don't have a test meter.
The light is bright on all hot circuts and is getting power all the way to the positive side of the coil.
I have a new ignition switch that I can plug in and try.
85 W150 318
I installed a new ECM, Ballast, & Coil.
All the fuseable links and places that should have power light up the test light except the Negative side of the coil.
Is there anything in the interior wiring that would prevent exterior wiring from working?
The only thing plugged in on the...
Fuel filter got changed with the new pump. The poly tank doesn't rust but the sending unit and tube does. not to mention years of sediment from 1985. Been in these tanks many times and they always have crap in the bottom of them.
The strainer is probably rotted and not stopping anything.
Well guys it was my original thought of it being fuel related. I first put on another coil and had the same result. Then I put on a rebuilt distributor. Same result. Hooked up a gas can with a hose straight to the pump and it climbed the hill like it use to with no power loss. The distributor...
Chain has been replaced. I will check slack when I am there at the distributor.
I always change the timing chain when I instal an engine because of the factory plastic coating thats usually chipping off and chain stretch. Its been a few years since I installed the engine though.
It has dual exhaust with no converters.
The gas can is a great idea directly to the pump.
That's what I do when testing an engine that has sat for a long time so I don't pump old gas from the tank.
I am taking a new dist and coil out there tomorrow and trying it first. Rained hard here all day...
Choke is working properly. I even put a clothes pin on the butterfly to see if maybe it was closing with acceleration from a weak choke thermostat. same result. It closes when cold and fully opens when warm.
Hey Guys,
I am stumped at what might be causing a loss in power while accelerating.
At first I thought that there may be a clog or the factory 1985 rubber hoses collapsing in the fuel system.
Replaced the carb, fuel pump, fuel filter and rear passenger fuel hoses and the hoses on top of the...
