Changed out the hydro-boost unit..... again.

I think we get ours from Mc Master Carr. https://www.mcmaster.com/#rivets/=17f4djr

Check or replace fuse #17 in the attached picture. It's labeled the Engine Control Fuse. That fuse controls the GEN2 relay, Voltmeter relay, Water in Fuel light and other things. If that fuse has no voltage on either side of it, then check the fusible link red wires on the terminal block on the...

Looks like a nice vehicle. You might as well start looking for a second one, your parents will want it.

I agree with checking the linkage to ensure that it moves freely. I had the same issue on one of my trucks. Some lube on all of the connecting components helped substantially and kept the motor from overheating. The wiper motor has +12 volts to it from the fuse box. It gets a ground command...

New injectors, new IP and new valve cover gaskets. So much fun.. Maybe I will attempt to change out the glow plug card.

Try some Goo Gone on it.

If you have a voltmeter, check the voltage on the large terminal of the glow plug relay that has the orange wires. Need to know what the voltage is when it is closed and providing voltage to the orange wires. I think you either have a bad GP relay or multiple glow plugs that are not working...

http://www.murcal.com/Catalog/Metal-DC-Contactor-Family/974-1215-011-09 I have bought quite a few of them from Murcal. They are very good relays.

I bought mine on Amazon. https://www.amazon.com/gp/product/B000C9D1SW/ref=oh_aui_bia_detailpage_o04_s00?ie=UTF8&psc=1

Prices for the IP's are on the OFI web page. The one I needed was $521.10 I sent a core in after the new unit was installed. They issued a credit for the returned core without any issues.

I have used Oregon Fuel Injection with great results. https://oregonfuelinjection.com/

Congratulations on getting it running. Keep us updated with the restoration progress.

Move your push button to the other Blue wire on the GP control card. Or wire it directly to the Light Blue wire on the GP relay. Sounds like you are grounding the Dark Blue wire that goes to the Wait light.

Been there many times and have never been disappointed. It's worth the trip to find parts and to see a lot of friends there. Keep up the good work and thank you for having a great show!

Removed and replaced the decaying lower radiator cushions. Not to hard to do if you remove the inner fender. The one had a stone wedged in it.

Welcome to the site from State College.

Do you have 12 volts on the top terminal of the GP relay? With the relay closed, do you have 12 volts on the bottom terminal of the GP relay with the Orange wires?

Please use a good known engine or chassis point for ground during testing and voltage measurements.
