Whiny Rant - [Don't waste your time to read]

I had three days vacation I had to take before Nov 1 or I lose it, so I decided it was time to get off my butt and get the Healey running again after the fuel pump died.

Flash back several months ago. My car did not have the SU installed when I got it, but had a Welbro bellows pump in it. I liked the pump as it sounded much like an SU does and is not polarity sensitive. The bad news was that the old bellows are not modern fuel friendly and turned to utter goo after what I think was a couple of decades of use. A couple of months ago, I got a rebuild kit (for $12) but couldn't get the thing working again.

Since going back to a SU would mean replacing fuel lines, I went to NAPA to get the Facet that everyone recommends and let the counter guy convince me that the one he had in stock was the same one, but just had an in-line filter. I got home and found out quickly that in fact, this one was polarity sensitive. I tried to return it and they wouldn't do it as I had hooked it up "backwards". (I asked the polarity question when I bought it, he forgot that part of the conversation. I won't use that NAPA anymore). I didn't want to mess with the polarity at that time, and the car sat while I piddled on non mechanical things.

Anyhow flash forward to yesterday. The Welbro dealer is actually in the DFW area, so I was going to run over an buy a pump just like the one I had. I called to check hours, and they are closed for the rest of the week. Coincidentially exactly matching my vacation. I cursed at this time.

Wanting to get the car back on the road, I took the "broken" Welbro back apart and assembled it again. I had done this a couple of times when I originally tried the rebuild, but this time it worked. I put the pump back in the car and fully expected the car to fire up without much trouble. (It started very easy before).

Anyhow, the trusty Optima battery still held a full charge, I turned the key and heard the pump fill the carbs with fresh gas, pulled out the choke and hit the starter. The motor just spun and soon the smell of a flooded motor engulfed my garage.

With great frustration I tried to figure out what was going on. I waited and sprayed starter fluid in the carbs hoping to hear the car try to catch, with no sign of life. Everything was great before, I don't understand what could be different now.

Remembering the adage that 90% of fuel problems are electrical, I got a checklist out to trouble shoot the ignition that I had. I pulled #3 (randomly to see if I could see fire) but I only got spark a couple of times. The checklist I had suggested starting with testing the coil on the multimeter. The coil I had is the original Lucas (manufactured 11-56) and would be a good candidate. The checklist said I should have listed 1.5 to 3 ohms as normal for the
SW and CB posts (and mine reads 3.2 ohms) and the SW and HT should be between 6000 and 30000 ohms (mine reads 6.84 kOhm). So it was a little out of spec. I didn't know if that was enough to worry about, so I posted that to the Healey list. I got several emails telling me it was my rotor (which I had already replaced with one of the "good" ones.

Thankfully, I was reminded that Kip Motors is only about 15 miles from here, and even though Healey's are a little too common for them, they would probably have what I need. I bought a coil, NOS points, condenser and one of their good rotors. They are the manufacturers of the rotors that don't short out as well as the new distributor caps for the Lucas DM6A (which had been out of production). I had a NOS cap in the box at home, but was very impressed with theirs. It has brass contacts, and it noticeably better built than my old repro.

The highlight was getting a tour of the facilities where I saw a Touring bodied Sunbeam Venezia (supposedly 1 of 4 left) that was about to go to California as well as seeing their "pattern" cars. They have a couple of dozen of the more offbeat British cars in an attached warehouse of Humblers, Berkleys, Sunbeams, Austins and the like that the use to check originality on parts. Very cool and unexpected. I want a Jowett Jupiter now.

Anyhow I got home and started to replace everything one part at a time. First the coil, then the rotor, then the cap and wires, but I still haven't gotten it to start. When I got to the condeser I dropped the washer to insulated it from the point spring so I pulled the distributor and am going to disassemble, replace the point assemble and condensor and clean it tonight. I was also told to check for a ground strap under the point plate so I am going to check for that and go from there.

I am highly frustrated as I am two days in and am still working on a problem that I didn't know was a problem. I was supposed to be driving around the neighborhood today and tomorrow hooking up the horns and such. I wan't supposed to be having problems just getting the car to run. ARRRGGGGHHHH!

Sorry again for the rant,

Hi Patton,
Sorry for the frustration. You might want to check the ground strap from the frame-to-engine just for fun. Also, how's that kill switch inna' trunk?
 
It always seems to be the last thing you look at, just like the missing keys. You have the tools and technology. The drive will be all the more enjoyable when the pain from slapping yourself on the forehead fades. I have nothing to say to aid your troubleshooting other than fuel, air, spark (and a little timing). The spark is the pretty much got to me missing if you are not flooded out completely, and it doesn't even pop. Keep us aprised.
 
Patton, if it is any consolation or inspiration I had a similar hair pulling problem with a Sprite once, it turned out to be a bad condensor.

Do you have the Lucas ignition fault finding manual, it has a series of fairly easy laymen type tests you can do if you have or suspect ignition problems.

Greg, Greg and Jon,

The switch in the trunk is long removed, so that's not it. I will double check the engine strap in the morning

I don't remember seeing the Lucas ignition fault finding manual, they should issue that with the car. I Googled "Lucas ignition troubleshooting" and came up with the below two links. I have read Les's articles before, but missed this one, and the PDF by Doug Lawson looks like it will be really helpful

I'm just ticked off because 1, I have trouble shot my way through ignition probems before w/o this kind of trouble and 2, I really EXPECTED to have a running car today.

Thanks for your time. I cosmetically cleaned the distributor tonight, and put it aside for the evening. Tomorrow I will break it down and troubleshoot from there.

Patton -

If you have the 12 port head, put your hand on the back of the intake manifold (i.e. the part of the manifold facing the bulkhead) and check to see if the casting plug has blown out.

If starting fluid didn't get it going, my guess is the motor is getting too much air.

Usually my check sequence is the following:

1) first pop the tops off both float bowls after turning the ignition switch and make sure fuel is in each bowl.

2) pull a plug and make sure it is sparking when the motor is turned over

If there is a problem with either one of these things (i.e. spark or fuel), then since you've checked the last part of each of these things you can work your way backwards from there and find the fault.

Happiness is a function of low expectations.

I NEVER expect a Healey project to come out right. Usually, my expectations are met. Sometimes I am thrilled.

You mentioned a "trouble shooting list". I need a book of those.
 
Here is the book I referred to:

https://cgi.ebay.com/ebaymotors/Triumph-S...sspagenameZWDVW

or e-bay 160290191121

The seller lists it as for Triumph, but it is a generic manual to Lucas electrical systems of the 50s 60s and 70s, it is a nice resource and worth the price, well laid out and understandable testing procedures for finding problems.

Moss used to sell them, but I don't think they do anymore for some reason
 
aha, now you know why I've gone pertronix. Had that type of BS happen to me too many times.

Glad you got it runnin!!! congrats!
 
Today is Halloween so all of the scary monsters are walking around.... Like Lucas, prince of darkness .
:devilgrin:
If new points don't solve it, temporarily run a wire from an always on 12 volt source like the big terminal on the starter solenoid straight to the coil. That will tell you if your ignition switch is " taking a holiday " on orders from the prince of darkness.
:jester:
 
Oh man! I totally should do that as my halloween costume. A big black cape and I can glue to it the boxes of non-functional lucas bits I have in the garage.

Or better yet, reverse wire a photovoltaic sensor, so the lights on my costume only light up when the sun is up. Heh.
 
Since you had one plug out maybe this is pointless (no pun intended) but did you take out the plugs and dry them (sometimes I spray them with starting ether to help dry) before trying to start with starting ether?
