This is over my head. The tech said it was like jumping the pump, it which case it would run whenevr the ignition was on. My problem is finding a guy or a shop that knows this stuff. Is this something most experienced mechanics would be able to diagnose? The guy at the shop and the manager both...

DOn't quote me for sure on the numbers But I think the manager the fuel pressure is supposed to be 12 and it's 2. But it's a nig drop in pressure.

Don't bother commenting anymore Bill if you are just going to insult the shop and not be helpful or constructive.

They did use a fuel pressure gauge and said that at the fuel rail the pressure is waay below what it needs to be, They also troubleshooted the distribution box so they know how to use a fuel pressure gauge and a voltmeter.

This is a very reputable shop, They have done other work for me and did a great job at a great price. Two mechanics have gotten it to start by applying ground directly to the pump jumping/bypassing whatever electronics. The mechanic did not say the fuel pump wasn't outputting fuel, He said that...

OK, So I towed it to a nearby shop I trust. Then did troubleshooting on it for four hours. They found that everything fuel pump relay wise in the distribution box is getting power and ground, and that the fuel pump is getting power. But there's a big loss of fuel pressure between the tank and...

Thanks, the issue is that my truck is parked in the shop's lot. The 2nd mechanic got these readings. The shop tech quoted 4-6 hours to check the wiring, But to be fair he had only isolated that the distribution box is the issues as they got the ranger running for about 10 seconds ..again by...

How l how long would you estimate it would take a mechanic that knows what he's doing to do this?

Also let me give you more background I had a 2nd mechanic over for an hour and he took the new fuel pump out and our the old one back in and then used a voltmeter to check the fuses and relays in the distribution box and he said everything looked good, Then it started to rain and he wasn't...

The 2nd mechanic I had over that checked that, measured with a meter and it was clicking or whatever it supposed to do. And the relay as also been swapped out with a different relay so I don't think that's the issue. I've also ran a jumper wire from the + to - pins into the module the relay...

What do you mean by the relay? The starter relay that's bolted to the fender or the module that plugs into the distribution box. I don't really understand what you mean by +side of the coil. The positive terminal on the starter relay? The shop tech seems to be planning on checking each wire in...

Hi, So this is my final follow up. I had to wait for appt at a garage. I just got a call and they verified it's a wiring issue in the distribution box. That's good but the shop tech is saying it may take four hours or more to trace down the issue, or issues. I think it's a broken wire or bad...

Regretfully....This a follow follow up. I won't go into the details with my former mechanic. I think he was in over his head to figure this out. He had done a tie-rod and exhaust job great. One thing he found out is that the problem is that the fuel pump is not getting power. We also tested a...

So I turned the key on and the fuel gauge moves a little and shows 1/4 tank, which is correct. But the gauge is at a bit above 1/4 tank with the key off. All of the gauges move whith the key on. I'm not sure if that points to the ground or not.

Maybe the G103 wire was damaged? Is that the ground for the fuel pump?

Well, He's under 30 and has a voltmeter and can read codes. But he is also stubborn and was just focused on the pump. I'm giving him another hour or so and it's not running I'm going to find someone else. Also, one recent reply said it sounded like the starter. I don't see how, Can the starter...

I'll show the diagram to the mechanic, it's over my head. Thanks for the input.

I believe the G103 ground that's right next to the starter relay and bolts to the firewall was cleaned up about a year ago when I replaced the starter. I checked it and the connection is clean. We took a grinder to clean up the area where it bolts to the firewall. I suspect its something in the...

Why do you think it's the starter when it cranks over and has started. The problem for sure is that the engine is not getting gas. That's one thing that we know for sure. How can the starter affect the engine not getting fuel?

I think Airline tech was right, He's done a good job replacing my exhaust. But all he's done to check power to pump is switch out the relay modules, Which I did before he cane over. I think this is simple but over his head
