VX electrical issues -- no spark
 

Hi, my long livin' VX is probably on its last legs. Inspection woes aside, it now won't start. It cranks over but the mechanic where the car conveniently died says it has no spark and that it's probably the distributor(?) His English is not so good: he said the 'coil' and pointed at the part where the spark plug wires come out of. I want your opinions on whether this is the likely culprit. He seems like a nice guy--he helped me push the car when I tried to bump start it (which failed repeatedly).

Some other considerations: couple years ago the dome light started working intermittently, then stopped working altogether. Very recently the left turn signal sometimes doesn't work (probably about 10% of the time it won't work). An intermittently working turn signal (and formerly dome light) seems to me might represent a big underlying electrical problem. I'm just afraid it might not be worth fixing.
Might WD-40 and changing out those wires solve the problem? A new distributor is quoted at $150 so maybe I should try the WD-40 and wires before betting a new or used distributor.

My former '95 VX had an intermittent starting problem at 200,000 miles. Sometimes it would just click and the starter wouldn't move. I also noticed the tachometer would sometimes jump around. I bought a new starter thinking it was the problem. No dice. I finally determined it was a corroded ground wire from the chassis to the transmission or engine block (can't recall which) on the passenger side. Your problem sounds like it's the igniter. A wrecked 1985 CRX that I bought for parts in 1989 (for my CRX HF) had a great running engine that I started once every 3 weeks for a year. After a year, it would turn over but not start. My old 1986 CRX HF died as I was pulling into my driveway and had the same symptom. It would crank but not start. It was a bad igniter.

All those small electrical problems are unrelated. Fix things as they need to be fixed. The coil is in the cap on the VX. The coils don't usually go bad, but it isn't out of the question.

So what do you recommend? I have no money and I'm not sure how long it is going to take to find a used distributor. Is there an alternative to replacing the distributor? Are you saying I just need a new cap?

Repeated bump starting is hard on the electrical system, btw. It probably caused the main relay under the dash to fail. It can be fixed pretty easily with a soldering iron. Does the fuel pump prime when the key is turned to the RUN position?

BTW, don't solder like the dude shows. Make sure the iron is very hot before attempting to solder as prolonged heat on the board will cook the components rather than just re-soldering the connection.

:confused: How does that work? The only thing I can think of is the EOC, not the bump start, draining the battery until you bump start and then having to charge the battery again.

I'm curious too. I turn my car off way too much. I turn it off all the time for the smallest of savings, because I don't mind and it's easy to do. But maybe I should cool it so I don't toast the new used dizzy coil I just paid $100 for (with labor).

I've bump started my cars for the last 22 years ('86 CRX HF, '95 Civic VX, and current '95 Civic DX) without any electrical, clutch, battery, ignition or other issues.

Rephrase, repeated bump starting of a car with a dead battery is hard on the electrical system. Check out the battery charging threads. It's the #1 cause of alternator failure, to run a car that has no or low charge. Less system voltage is going to put more current through the main relay. You always want to have a battery in the car with good standing voltage.

It is not hard on a car to bump start it if the battery is in good shape. This, however, was not the case with the stated vehicle.

I'm happy to back my claims.

The coil or the main relay was overstressed enough times due to the low battery charge that one of those electrical components failed.

Please, just check the main relay for failure.

That makes sense. :thumbup:
