Hello all, I just picked up #539 in the Northern VA area and wanted to introduce myself. I believe it is already on the Registry, but now with a new owner. It needs some TLC, but I'm really excited about it. I've posted a couple of pics. They're not the best, but once I get her all fixed up I'll post more.

The ECU tells the fuel pump to run, so it doesn't seem likely that's your trouble, though possible. To check the cam sensor depth, if you have no tools, hold the new and old ones up to each other so the end of each touches the flange of each. They will probably be identical so you can assume the shims that worked in the past will work with the new sensor. The shims are more likely to be dependent on individual case machining than difference in sensor length. Since you're already installed it, if the shims are in, ok. If you installed it without shims, pull to see if the reluctor has shaved the tip of the sensor. The schematic I have shows that the sensor is a simple analog coil, the third wire is in fact a grounded shield to keep AC voltage from messing with other electronics. The wires on the ECU side of the sensor connector should be tan and white, pins 7 and 12 on the ECU connector. With a second helper and a digital multimeter, you can test the sensor at both plugs for AC voltage output while you crank the motor. The coils are powered along with the fuel pump and injectors by the fuel pump relay. Fuel pump primes...Yes? pull an intake boot back, open the throttle and look with a flashlight into the open throttle body. When you first turn the key, or perhaps the run switch, the injectors should spray for a moment, to prime the engine. If you can confirm that you have fuel from the injectors and signal from the cam sensor, then we can look at the magic box. Until then, I'm with Dr. House; "It's never the ECU".

I think we threw wine bottles off a porch in Northern Virginia once

I am sure it is. He has new relays coming.

This sounds like you have a broken relay...

Whats the battery voltage when do you you hit the start button? How old is the battery?

56840 | Lisle Corporation This relay tester is perfect . I have the set. Click on the underscored portion and it will take you there.

Get one of these . You have no idea how important it is to use one. You can test every pin and function w/o poking, prodding around and damaging terminals.

its not old - I'll charge it up and test.

Thanks, I'm real happy with how it turned out! Usually the lighting looks terrible on my phone camera.

^^^^^^ Ah, yes, the brown and white food group; a favorite. In this instance, Eggs Benedict with hash browns and scrapple. Unsure of actual "white stuff" over the eggs. Not biscuit gravy; possibly SOS, tho classic EB gets hollandaise sauce. I immodestly view myself as a connoisseur of (white)(sausage)(pepper) gravy, and, especially, of "proper" biscuits. I do not care for SOS and find hollandaise sauce a bit "uptown" and "yankee" for my southern peasant tastes. That said, yes, I'd go back anytime near. Bill

We'll see, haven't told the missus yet!

I am in the process of purchasing 694 here in New Zealand. It's been off the road for a few years (7!) but lives.

So good to finally find out this here back story… I’ve always been intrigued by pics of this lawn tractor Sure hope it stayed as is! It’sa what happens when some good ol’ boys get on the weed instead of cutting weeds 🤣

Coppa and Nero carbon fenders treated with a couple of layers with clear coating. Nero absolutely ready for next year. IPA time. Cheers Tom. Sent fra min SM-S906B via Tapatalk

I think you spelled that wrong... https://en.wikipedia.org/wiki/Merkin

It's Merican for "modify" for performance or a variation on what we would term "hot up" Phil
