Inertia switch 85-91 is on the inside firewall above the wiring harness

So I assume a small amount of fuel is coming through, but not a measurable amount. do the test I said in previous postAlso I am NOT your BRO. I find that comment to be disrespectful and unnecessary With that said Done here. Good luck. Hope you solve your problem

Because the fdm is shutting off the fuel flow. the high pressure pump can't supply fuel the the rail if it can't pull it thrpugh the modual.Ok, so let's explain what this thing is. there are no check valves in this fuel system. so when you switch from rear to front the fdm switches where the...

the fuel delivery modal is bad. it's the part in the frame where the 4 lines come in, 2 lines go out, then it goes to high pressure pump. here is a picture of the system when I was building my F 350It is the round can looking thing to the left. You will find it is not rebuildable, and is...

light bulb is burned out and shorted across itself. replace the bulb

They are not check valves, but are pressure regulators to keep from blowing out the check valves. If you put those on a 87-89 you will have a real problem as that IS NOT THE PROBLEM.the recalls were for 92-97 which has a check valve in the fuel pump. Those turcks have a 2 pump high pressure in...

Some origional members that stuck it out through thick and thin have been given a feeling they dont belong. Only reason I answered here is because Billy hit me on Facebook messenger about the thread.You need to concentrate on old members that were active before, and stopped posting to see...

Make sure to use a 94 wiring harness for the battery. It comes with the hot wire from battery to starter, battery to solenoid. also has a new trigger wire, half the size of the original.Have done this swap on 3 of my bricks. The 90 351 starts so fast I doubt the flywheel goes all the way...

These are on ebay

AIR leans out the heads and cat. Eventually you will carbon up the valves. It will also cause your fuel mileage to drop. There is a silicon hose kit that is available for patching rusted or damaged heat pipes on cat or AIR systems.I would replace it

Someone has put a 85-91 filter in there. 92 to present is longer so you can get the tool in there.You have to cut the filter off between the rib and the line, then put the tool in the line and grab what remains of the filter line with a pair of needle nose pliers. The springs that hold the...

You have to run until the thermostat opens. If you run on warm up you are not running the whole system, only through heater core, and top end {and in your case 5.8 throttle body} until it opens. once it opens the heads and block become involved

My exhaust tester is a dollar bill. idle the truck/car. Walk back and hold the dollar bill by the edge, take it near the pipe. It should flap and try to blow it away. If it flaps and sucks it in and flaps you have a miss on a cylinder.

Lookie here Can't let you out do me! Added a electric fan and modern high torque starter too

No throttle pin on your or his truck. He is talking from YouTube. At least he tried to help you I Thank him for that. No one else doesYour new symptoms I answered. Sorry.

Coolant instantly spitting out of a closed system is vapor lock. Better pressure test. You may find your miss. My bet, a head gasket is going south. What happens if you let it sit and idle to get the vapor lock out? Hopefully I can check back in, if not, pm heavy doc, get him to text me

Yeah. Right. That truck probably has 2 feet of dust on it by now......

Missed the other post. Not able to use the phone anymoreThe wiring harness changed. Not sure when/ what model. Pretty sure if your luck is like mine you will need the kit if you dont order it

I re-wired my lift pump on mine to run constant. Just make sure to keep the pressure below 5 lbs. No faith in a mechanical pump anymore

Nice!I'ma gonna nickname him Tom tho....... 🤪

Very nice! I had a 74 that same color. Sorry when I had to leave that truck goSent from my SM-N960U using Tapatalk

14.95 is ok. What does it do while your watching it and someone starts turning everything on?Sent from my SM-N960U using Tapatalk

I thought you had already changed the coil a while back. I'd go for that. Coil break down inside can be very contrary.I'd also think about putting a volt gauge on it see if your getting some feedback from your alternatorSent from my SM-N960U using Tapatalk

Like jake said, careful with Volvo parts. There is a reason most Volvo's and Mack's are now automatics. My son has a fairly new tractor deadline because some clutch parts are unavailable Same with his other truck. Front end parts are ordered, nonexistentSent from my SM-N960U using Tapatalk

Watch the firewall. Early trucks used to crack and break from clutch. They made a plate for them. I have it on 2 of my trucksSent from my SM-N960U using Tapatalk

What would happen if you machined the bushings out of hardened steel and put a grease zero in there?Sent from my SM-N960U using Tapatalk

I would change the oil to the Rotella first before I did anything. At least that will tell you if its a lifter issue or not.Flat tappet motors dont like synthetic oil, so once you freshen it up, at least use a synthetic blend.I remember a while back an additive of zdp you could put in them...

You already have the mechanical gauge, so that would be the test.Not sure what oil your running. The old girls don't like synthetic. Try some shell Rotella 15w 40 diesel oil in there. Could be lifter issue as well. I'd probably pull it and freshen it up, being your keeping it forever. Money...

Yeah, I wouldn't be running it a whole bunch like that. Could be other things, but oil pump is a startDo you hear any ticking or rattling at idle?Oil pump is rais motor, pull pan, pull pump, replace. Not as easy as I made it sound.... You should pull some bearings and see how they look, rod...

So that is all normal. No vacuum leaks. I would clean the fuel rail, then if still having a problem do a compression check.Sent from my SM-N960U using Tapatalk
