2000 civic no start
So my em1 will crank but not start. Here is my situation:
1. Fuel pressure, yep
2. Spark, yep
3. I took off dizzy cap and checked, its clean
4. Has been hard starting lately
5. After testing for a while I pulled plug and it has fuel on it, but not like fuel fouled, just from me cranking but no start.
What's next? I was thinking main relay, maybe fpr?

Re: 2000 civic no start
i ran a spark intensity test and it jumped about 30 on all 4 cyl. i have not checked timing because by the sound of the cranking it sounds like i have good compression, bc it almost starts, but doesn't. anyway the timing belt was done at 101k, and i bought it last spring at 147k and have been driving it since with no problems, its really strong when it runs

Re: 2000 civic no start
Any CEL codes? Are the plug wires possibly installed in the wrong firing order?
If you have strong spark and the injectors are spraying fuel, it's time to check whether the timing belt skipped a tooth and to compression test the cylinders.

Re: 2000 civic no start
UPDATE: (sorry ive been out of town)
compression #s from cyl 1-4 (approx.): 95, 45, 95, 95. Comp tester adapter was covered in oil after testing each cyl.
I poured some oil down the cylinders and comp tested again. Numbers were around 120-125 on all 4.
I pulled valve cover today to check timing belt. Seemed slightly loose to me, but haven't been able to rotate engine to check timing marks due to the fact that the car is on a slanted driveway and my jack just blew up and leaked fluid everywhere.
Thats where I'm at so far. Right now I'm thinkin bad rings, but could timing also be an issue? Would there be enough interference to make a lot of noise if timing was off half to whole tooth?

Re: 2000 civic no start
I have no clue but I had a similar situation with my moms Honda CRV. One day it would crank but not start. I also checked everything then I noticed that before I used to start the car, it would make an alternator squeeking noise. So I decided to tighten the alternator belt. After, I started the car and it ran.. go figure

Re: 2000 civic no start
I did do my belts a few weeks ago, but I usually error on the side of too tight. Besides I've never heard of that happening before. You sure it was the belt and not just a coincidence?

Re: 2000 civic no start
Side note: When I ran a fuel pressure test a while ago, it was at around 60psi. I think the specs are b/t 40-47psi. Is this another problem to address? Maybe fpr?

Re: 2000 civic no start
I think you should repeat both tests (dry versus wet) to confirm the numbers. You also need to remove the ECU fuse so that the injectors don't spray fuel in the cylinders during the test.
60 PSI is definitely a high fuel pressure. If you don't have an aftermarket fuel pump, then check the FPR and fuel return.
