Help! '91 CRX HF no start
I'm out of ideas on this one, appealing to the experience of the group:
Bought a non-running 1991 CRX HF. It had stopped due to a broken camshaft, and had been stored for 6 months. One of the cam bearing surfaces was suspect, so I bought a used, head from a guy that had upgraded his. Cleaned all up, replaced the bad head with new one. Now I cannot get the engine to start. It cranks fine, and gives a few indications that it's trying but no start. I can see a weak spark, but it's not enough to fire a timing light. Here's what I've replaced: 1- Gaskets of course, bought a head set. 2 - timing belt, seals. 3 - New plugs 4 - new distributor 5 - Gas - drained tank, added fresh gas, bled filter and manifold. I've re-checked the cam timing many times, and I'm certain it's right. Distributor seems to be oriented right (not 180 out) Moving the distributor through it's timing range by hand while cranking does not make it fire. I oiled the cylinders while it was apart so they wouldn't start up dry. Plugs look good - not oil fouled. So what am I missing? I've gotta think it needs a fatter spark, but the only thing left is the ignition wires and I can't see all 4 going bad just sitting. I'm ready to take it to a shop, but it's a major PITA to do that this week. Suggestions? -- Rex Burkheimer Fort Worth TX |
Re: Help! '91 CRX HF no start
If you have a weak spark, how about the coil (if you had a distributor
with points and condensor, I'd say check the coil and condensor)? You haven't mentioned that component yet. You KNOW it's good? Coils RARELY have problems but it is something you should check. Put a known working coil on and see is the spark is stronger...borrow one just for testing purposes, but if you have to buy one, at least they're not too expensive, especially from a junked (auto salvage yard) car. If your coil is in the distributor, as in some cars today (don't know about 1991 era cars), then check it there. As you probably know, a car has to have 3 things to fire: Air, gas and a spark...assuming the timing is not messed up but that would affect RUNNING, not starting. Good luck, John D.

Re: Help! '91 CRX HF no start
Then maybe you're still off, even 180 degrees off although you say you
can't be. Check that aggain. How do you know the spark it weak? Go to your local auto store and buy one of those sparkplug spark testers...they attach to the plug and then to a ground. Test the spark ar night on all of them and note any difference in amount of spark. If they are ALL have weak sparks, are you SURE the coil checks out okay? I know it -- and the igniter -- is new, but you're sure it's not defective? As for air, it needs to be in the proper ratio (with gas) needs to be present..it's not flooding? Even with a GOOD spark, it won't start flooded. You may have to take this one to the pros, but then I am just a DIY guy...maybe a good mechanic can nail it down. I hope it's not your ECU. John D.

Re: Help! '91 CRX HF no start
Well, I got the CRX going last night. I thought the plugs were new. They weren't so I changed them. While they were out I squirted some fresh oil in each cylinder. Nothing much changed, but the battery was running down. So I connected a charger for a few minutes, then I got impatient and hooked up my booster pak. Now it spun a lot faster and fired for a few rounds until it died again. The timing light was now working too. I let it charge a little longer, tried again. It fired again, but I had to keep cranking to keep it running until it was able to sustain itself. After that it was OK. Conclusion? I guess that althought the battery was fresh, and constantly on maintainer charge, it had enough juice to crank but not enough to energize the ignition. The booster pak brought it up enough to fire. Had I monitored voltage while cranking I might have caught this sooner, but I didn't have an easy way to do this with just two hands. Unloaded battery voltage was 12.55 which should indicate a full change. Besides, most cars that crank that fast have plenty of volts for ignition. Perhaps because this is an HF with some miles on it it spins very freely even with low voltage.

That's why it's hard to believe it was your battery...the starter requires A LOT of juice from it...it can spin the starter yet it can't start the car? Unbelievable.

That's why it's hard to believe it was your battery...the starter requires A LOT of juice from it...it can spin the starter yet it can't start the car? Unbelievable. Again, it sounds like the coil not building up volts to the spark enough. But you got it running. Still, don't become complacent and think it's over...it may not be yet. Good luck though, John D.

Re: Help! '91 CRX HF no start
Had a similar problem with my '94 Integra. New plugs didn't help, but new
plug wires solved the problem.
