87 f150 no power to coil I put a new coil, module, computer and relays what could it be if I run a jumper wire to either side of coil relays click but no spark to dist
I'm not good at wiring buy it looks like but it looks like a orange wire from the starter to the module should power the module to put power to the coil.correct
Power from the ignition switch is what powers it when cranking. That wire is red/light green. Then when running, the same wire gets power in that same wire through the resistor.
Thanks Bert I got it running thanks to that diagram there was no power from the switch so I jumped it from the battery. I have to get a switch now it runs fine sitting there but when I went to move it there was no power and popping is that because I have it jumped and not a switch? I was looking at the diagram wrong at first then I saw the r/lg wire turns to w/lb.
It needs to go through the r/lg so the resistor feeds the coil. Get the switch and see if things work out. The coil shouldn't get the full voltage when running.
No but I don't have a r/lg wire mine in w/lb on one side that goes to the module the other side has 2 g wires one has a red wire to a resistor connected to it.I can't find a r/lg wire anywhere.Coming off the switch on the column there is a r/g wire thats pretty thick, I ran a hot wire to that but it did not work.
let me give you some background. It was sitting in my back yard I would start it once maybe twice a week and let it run 10 minutes or so then I didn't start it for a week or two it wouldn't start after that for about a week then it fired right up one day started it every day for a week went away for the week end and here we are a month later spending money and no results.
The brown pink wire should have power at the switch when turned to start. Maybe the switch isn't moving far enough. The start wire, red/light green goes to the starter and is a separate circuit in the switch.
I found it there was power at the switch so I started to test the wires that came thru the firewall and under the main harness there was 2 wires with fuseable links so I pulled on them to get room and 1 pulled apart so I cut it and spliced a piece of wire in and relays clicked and fuel sprayed. Bert Thank You for all your help!
okay now that its running I took it up and down the street it will not shift out off 1st gear,I guess because it sat so long.It has a 3 speed in it 1-d-od any thoughts
